Respiratory Drugs Respiratory System Drugs

Methylxanthines

Yet another type of medication used to improve respiratory function is Methylxanthines. Some examples of these include Theophylline. These types of agents work similarly to bronchodilators which open the airway passage, in part by relaxing the bronchial or smooth muscles in the air passage ways. They also help promote greater circulation and engage the central nervous system so it can more actively work to provide oxygen throughout the body. Because these medications may result in increased cardio activity, most doctors recommend patients with a history of cardiovascular problems use them with caution, or not at all.

Montelukast

Singulair or Montelukast and Accolate or Zafirlukast are agents that like the Methylxanthines act on receptors in the air passageways of humans called the "leukotrien receptors" especially D4 and E4. These receptors are responsible for what is known as an anaphylactic reaction in the body, where they immune system hyper or overreacts…… [Read More]

High Elevations and the Blood The Respiratory System

espiratory System: High Elevations and the Blood

Why do people experience shortness of breath at high altitudes? Why does tendency clear off after several days?

Humans experience two main types of environmental stresses at high altitudes. First, they experience rapid dehydration as a result of the strong winds and low humidity; and secondly, they could have shortness of breath as a direct result of the low air pressure (Boga, 1997). The estimated altitude of the Alps is 15,700 ft above sea level. The altitude of the U.S. is commonly taken at sea level owing the effect of the Atlantic Ocean. Air pressure and the concentration of oxygen in the air both decrease with increases in altitude, particularly because at high altitudes, the air is thinner and the molecules are farther apart. At sea level, the air pressure happens to be at around 14.7 pounds; at 10,000 feet, it is around…… [Read More]

Comparison of the Respiratory System of Fishes and Frogs

Fishes to Frogs: espiratory Adaptation

espiration Evolution: Fishes to Frogs

The energy needed to sustain life depends on the reduction of oxygen during glycolysis, thereby producing ATP, water, and carbon dioxide. As multicellular organisms began to evolve and grow in size, the ability of the inner-most cells to receive enough oxygen to carry out cellular respiration was compromised. The absorption of oxygen through the outer cellular layers, called cutaneous respiration, evolved to become an important method for obtaining enough oxygen to sustain the evolution of larger organisms (Farmer, 1997).

Ancient fishes depended on cutaneous respiration to survive in oxygen-poor aquatic habitats, such as rivers, swamps, and tidal pools (reviewed by Farmer, 1997; Taylor, Leite, Mckenzie, and Wang, 2010). Cutaneous respiration was sufficient as long as these fish remained small in size, but the need to avoid predation would have increased the evolutionary pressure to grow larger. The combination of size…… [Read More]

Human Respiratory System

Human Respiratory System

The drive to breathe is involuntary and generally automatic, although one can change breathing patterns, and they change when we sleep or are doing different activities. The lungs and respiratory system function to move air 24/7/365 because the body cannot 'store' oxygen that it needs for cellular respiration and energy production. Thus air is constantly flowing in and out of the lungs (Healthline Editorial Team).

Respiration, in terms of human physiology, has more than one definition: it includes cellular respiration, a process ongoing within the mitochondria, where glucose is broken down to ultimately produce ATP (adenosine triphosphate), providing energy to the body. As well, the body is capable of brief periods of internal anaerobic respiration, which produces lactate in muscles for example. However, the focus of this report is on respiration as the process through which air moves into and out of the lungs, in processes of…… [Read More]

Evolution of Respiratory Organ System Respiratory System

Evolution of Respiratory Organ System

Respiratory system functions in providing oxygen into cells and transferring the remains of metabolism. The basic respiratory system happens in two main ways: internal and external respiratory system. In internal respiration, organism experience gaseous exchange through the cellular surface, while in the external respiration, every organism has developed typical organs to carry out the process, like fetal membranes, skin surface, and lungs (Campbell, 2001).

Early organism (amoeba) carries out the metabolism process within the cell's organelle. In the mitochondria, organism converts glucose into energy (ATP) with oxygen, and releases CO2 and water. The respiratory process exists as gas exchange through cell's phospholipid membrane. This process continues for internal respiration principle in higher organisms.

Through the evolution, organisms have developed different types of respiratory organs, which suit their needs. The organs vary from gills (in fish), lungs (terrestrial organism), and skin (amphibians). Certain organisms may also…… [Read More]

Respiratory Syncytial Virus RSV Is

It has also been suggested that low-level viral replication associated with SV may be a driver in chronic inflammation in some sufferers of chronic lung disease, although this is so far uncertain (Openshaw, 2005). It is estimated that infants who develop a wheeze as a result of SV contraction develop a recurring wheeze in around two thirds of all cases. It is also estimated that around half of these children will develop some form of asthma (Lehtinen et al., 2007). It is unclear why there are some who experience delayed onset of SV, although both immune 'imprinting' and viral persistence have been implicated (Openshaw and Tregoning, 2005).

Diagnosis

The condition is diagnosed through rapid antigen-detection tests. It is difficult to diagnose SV in adults as the tests are insensitive in persons other than children, and practitioners rarely request tests for SV in adults. This means that it is difficult to…… [Read More]

Respiratory Syncytial Virus Bronchiolitis

Subtype a is the one that predominates in many of the outbreaks that are seen and presents much more severe clinical illness. It affects both the lower and the upper respiratory tract but is most prevalent in illnesses of the lower respiratory tract such as bronchiolitis and pneumonia. The obstruction of the airway in RSV can be very dangerous, and this is especially true of infants because their peripheral airways are much smaller than adults. Because of this it is very important to know what the warning signs of the illness are so that children can be treated properly and can recover fully. Infants between age two months and six months are most at risk for RSV, as are premature babies and babies that have other problems that may make their immune system not as efficient such as those that have lung conditions, congenital heart disease, cystic fibrosis, a lack…… [Read More]

Respiratory Ethics Nursing Ethics in

2008).. This points to the ethical responsibility of nurse educators -- it is not enough to treat the disease, bit one must treat the patient.

Failure to provide the proper level of education to a patient is certainly one way to fail them both ethically and medically, bit the opposite can also be true. That is, it is possible to provide too much care -- what is deemed "medically futile care" -- and this also raises very serious ethical issues in the realm of respiratory illnesses (Sibbald et al. 2007). This particular stuffy found that insufficient communication among the medical team was one of the primary causes for prolonging futile care, which often means increasing and/or prolonging a patient's discomfort without any reasonable expectation of an improvement in their condition (Sibbald et al. 2007).

The ethical choice here, of course, is to end care (with the consent of the patient…… [Read More]

Tissue Maturation Body System Effects

e. hypertrophy). In the elderly, this process is reverse. Hence, the functional reserve capacities of the skeletal muscles decline with age, largely due to diminished levels of physical activity. As a result daily tasks once taken for granted become progressively more difficult, and eventually impossible, to perform. In illustration, a great deal of muscle force is required to simply stand up or to climb stairs. Therefore, skeletal system is relying upon the reserve capacity of the heart to provide the endurance needed to perform such activities. If an elderly person does not engage in some sort of endurance-based activities, he or she will not have the cardiac reserve capacity needed for daily tasks. More importantly, diminished capacity may not counteract illnesses or diseases. Although strength-based activities help the cardiac reserve, it may not benefit the skeletal system. "While resistance exercise promotes fiber hypertrophy in skeletal muscles, the explosive power of…… [Read More]

China's Healthcare System China Is

More unfavorable publicity came in June when Jintao had to undergo medical checkups to ensure he was SARS-free when meeting President Bush and other G-8 leaders in France. There is little doubt that China's international standing was clearly badly damaged by its government's mishandling of the SARS epidemic.

On July 21, 2004, Dr. Bates Gill, Freeman Chair in China Studies Committee on House International Relations Subcommittee on Asia and the Pacific, stated official Chinese estimates show China now has roughly 840,000 persons living with the HIV virus and as of the end of 2003, only 62,159 persons had been tested and officially confirmed to be HIV-positive. "The remaining HIV-positive individuals in China, estimated at 780,000 persons or more, are not known to public health authorities, and the individuals themselves probably do not know their status, posing significant risks for the further spread of HIV." Yet, outside observers believe that…… [Read More]

Performance Reward System An Organization Can Achieve a

Performance/Reward System:

An organization can achieve a competitive edge only and only with the help of its employees. Therefore, it is necessary that right employees are selected then trained and developed and a performance-based reward system. The question then comes to the performance measurement system. In a furniture retail store where I work they stick to the old practice of a meeting of top managers and supervisor who sit down annually and critically review the performance of all customer service personnel. They carry out a thorough examination of employee performance with respect to the goal set for them by the management. In this setting where only goals are there to guide employees and performance appraisal system is vague and subjective, most employees are just interested in meeting their targets and they do not strive to exceed their employers expectations. Performance evaluation should be an evaluation and development tool with the…… [Read More]

Main Systems of Human Body

The circulatory or cardiovascular system is responsible for moving nutrients, wastes and gases between body cells, transporting blood across the whole body and battling disease (Circulatory System). Its principal elements are the heart, numerous blood vessels, and blood.

The heart forms the circulatory system's core. This 2-sided, 4-chambered pump which distributes blood to various arteries comprises of the right and left ventricles, and right and left atria. The ventricles, situated within the heart's lower half, are responsible for pumping blood to the whole body (away from our heart), whilst the atria, situated within the heart's upper half are in charge of receiving blood from different parts of the human body. The right and left ventricles pump de-oxygenated and oxygenated blood, respectively; de-oxygenated blood is pumped to lungs while oxygenated blood is pumped to the remainder of the human body (smith, 2013). These 4 chambers are connected to one another by…… [Read More]

Exercise and Cardiac/Respiratory Health

Heart health is positively correlated with exercise and, according to the research, physical activity can be a good way to diagnosis, detect or treat emerging heart conditions in individuals. Connections are also made in general research between exercise and both aerobic and anaerobic gains for individuals. Indeed, as the discussion hereafter will show, exercise is among the most consistently effective and proven methods of preventing heart disease and such causal conditions as obesity or hypertension. Research points to a host of indicators that suggest exercise should in some form be a regular part of every individuals lifestyle. Chief among these indicators is the evidence demonstrating that exercise and physical activity are directly related to cardiovascular and respiratory health.

Oxygen Hypoventilation and Hyperventilation Are Respiratory Conditions

Oxygen

Hypoventilation and hyperventilation are respiratory conditions related to differential intakes of air. Hypoventilation refers to the inadequate (hypo) intake of air, causing decreased levels of oxygen and increased levels of carbon dioxide in the body. The necessary gas exchanges for maintaining equilibrium become upset. Hypoventilation is caused and characterized by shallow and/or excessively slow breathing. As a result of inadequate gas exchange, carbon dioxide cannot be properly removed and levels of CO2 in the blood become elevated, a condition called hypercapnia. When levels of CO2 in the blood change, the body's pH changes too. Hyperapnia causes the blood to become more acidic, a condition called espiratory Acidosis. A person who has lost control over his or her respiratory system may not be able to self-regulate by breathing deeper or faster (Agrawal, n.d.).

Hyperventilation is the opposite of hypoventilation. Too much (hyper) air is being taken in and cannot be…… [Read More]

New Respiratory Drugs

new respiratory drugs that have been approved for medical use over the past decade. The paper will highlight the diagnoses of the drugs i.e. when and why it is prescribed, how it is meant to be used and how often, its side effects, the impact for a missed dose or an overdose along with any other relevant information that will add depth to it appropriate use.

The main purpose for the respiratory drugs is to help cure the ailments directly or indirectly related to the functioning of lungs or general breathing of an individual. There are numerous sectors where studies on new respiratory drugs can be carried out and some of the most recent studies to include this particular aspect include allergies, asthma attacks, Acute espiratory Distress Syndrome (ADS), pneumonia and sinus infections.

In this paper we will focus on the following new respiratory drugs: Arcapta, Daliresp, Dulera, Tyvaso, Alvesco,…… [Read More]

Grid-Connected Photovoltaic PV Systems Though

Batteries are common in individual household systems. Inverters could help, though their technology is not standardized. Automated demand response using smart meters with microclimate forecasting research is well funded (St. John). Building dedicated (express) feeders for larger PV systems with bidirectional voltage regulators is one response. Avoiding fixed capacitator banks and having the PV system absorb volt-ampere reactives are two other possible solutions (Katiraei and Romero Aguero 69-70). On the other hand, PV can be useful to a utility by improving the voltage profile and reducing electrical line losses (Srisaen and Sangswang 855), as well as "relieved transmission and distribution congestion, environmental impact reduction, peak shaving, and enhanced utility system reliability" (Ramakumar and Chiradeja 722-723).

PV has environmental issues. Making solar cells is an energy-intensive process, using significant amounts of water and toxic chemicals. Most good monocrystalline silicon is produced by the highly inefficient (80% waste) trichlorosilane (SiHCl3) distillation and…… [Read More]

Designing a Safety System Safety Management System

Designing a Safety System

Safety management system is a management policy to prevent or minimize injury within a workplace. Top organizations across the United States are increasingly investing in safety management because of the general believe that safety is central precondition to market competitiveness and "an integral part of high quality business operations." (Tervonen, Haapasalo, & Niemela, 2009 P. 17). Safety is defined as a state where all the business related risks are managed at acceptable level. Typically, safety management is a management policy used to protect workers from undetermined accidents. Safety management is very similar to corporate safety where corporate safety is a holistic management strategy to protect an organization as a whole against accidents, misuse, harm and crime.

Objective of this project is to design safety management system for Hobart Brothers Co. To design safety management system for the company, the paper provides essential components that could prevent…… [Read More]

Learning and Respiratory Care Problem-Based

In fact it has been proposed that the positive impact observed of PBL on motivation may come from these academically talented individuals rather than the intervention itself (Hwang & Kim, 2006). GPAs and demographic characteristics were not found to be correlated to PBL (Ceconi et al., 2008).

White et al. (2004) found in a study regarding that PBL was not shown to be superior to other learning styles in assisting students to acquire or retain knowledge regarding asthma management. This finding is consistent with the majority of research that has not found greater knowledge acquisition or retention amongst PBL students vs. traditional teaching methods (Albanese, 2000; Beers, 2005; Rogal & Snider, 2008). However, it is not that PBL produces inferior results, most studies have found that there are no significant differences between PBL students and those from traditional curricula on standardized knowledge tests (Beachey, 2007). Beers (2005) points out that…… [Read More]

US Public Health System

U.S. Public Health System to better assess and defend against threats from bio-terrorism and infectious disease. This report discusses public health agencies that are "exemplary" in providing public health services in some way or another. That only thirteen were chosen out of seventy-three initially studied indicates how difficult it is to find exemplary public health protection against infectious disease and bio-terrorism threats. Data collection and surveillance are two areas that need improvement, especially in the field, as this report clearly notes.

This report contains information about thirteen agencies that offer the best of public health services. It shows what other agencies need to do to come up to a level of exemplary services, and how far some have to go to catch up. For example, the authors cite the "Citywatch" computer monitoring system for the Illinois Department of Health. They write, it is "A sophisticated computer-assisted emergency notification system that…… [Read More]

Buffer Systems in the Body

Hypokalemia occurs when the blood plasma level of potassium is too low (below 3.5 mcg). This is the most common electrolyte imbalance. It effects cardiac conduction and function.

Calcium

Calcium is a cation that is stored in the bone, plasma and body cells. In plasma, it binds with albumin. It is well-known that calcium is necessary for healthy teeth and bones. However, it is also necessary for blood clotting, hormone secretion, maintaining the integrity of cell membranes, cardiac conduction, transmission of nerve impulses and muscle contraction. Calcium levels in the body are regulated by bone resorption.

Hypercalcemia occurs when calcium levels rise above 5 mcg in the plasma. One of the most common symptoms is cardiac arrhythmia. X-rays will show calcium loss in the bones when blood plasma levels are high. This is frequently a symptom of and underlying disease with excess bone resorption and the release of calcium. It…… [Read More]

Standardized Coding Systems and Nursing

Each standardized nursing language is designed for use in a number of clinical settings, including home care, ambulatory care, and inpatient treatment, with certain languages providing decided advantages within particular circumstances. Although it is true that "improved communication with other nurses, health care professionals, and administrators of the institutions in which nurses work is a key benefit of using a standardized nursing language" (utherford, 2008), the proliferation of several nursing languages throughout the years has inevitably resulted in discrepancies, wherein the personal preferences of nurses, the policy of a hospital's corporate ownership, or other factors determine when, where, and why a specific language is used.

To address the growing concern over the inability of nurse's to communicate through a single standardized language system, the International Council of Nurses (ICN) commissioned a comprehensive study which resulted in the International Classification for Nursing Practice (ICNP) being selected as the most advantageous option.…… [Read More]

Magnetic Resonance System on Patients Magnetic Resonance

Magnetic esonance System on patients

Magnetic resonance System (Imaging), here after referred to as (MS), or nuclear magnetic resonance imaging (NMI), is a medical imaging technique widely used in radiology to visualize detailed internal structure and limited function of the body. It provides great contrast between the different soft tissues of the body, making it particularly useful in neurological (brain), musculoskeletal, cardiovascular and ontological (cancer) imaging. MS uses a powerful magnetic field to align the nuclear magnetization of (usually) hydrogen atoms in water in the body (Adams, 1989). To systematically alter the alignment of this magnetization, adio frequency (F) fields are used, enhancing the generation of a rotating magnetic field by the hydrogen nuclei that can be detected using a scanner.

MS can detect the chemical composition of diseased tissue and produce color images of brain function. This signal can be controlled by more magnetic fields to build up adequate…… [Read More]

Problem-Based Learning vs Traditional Teaching in Respiratory Care Education

PBL vs. Traditional

Two of the methods of pedagogy that are currently employed in respiratory therapy are Problem-Based Learning and Traditional Teaching. Both instructional methods can provide a strenuous curriculum for the student interested in comprehensive training in the field of respiratory therapy, and each method has its advantages and (of course) its disadvantages. The focus of this study will be to determine which pedagogical methodology provides the most efficient and effective results in a respiratory therapy educational setting.

To accomplish that objective, the study will administer surveys in questionnaire form to students attending two separate schools that offer training in respiratory therapy. The questionnaires will provide a quantifying response to qualitative, and quantitative, information. Each school's pedagogy will represent either problem-based or traditional teaching methods and students from each school will be asked to complete pre and post training questionnaires and surveys. Additionally, students will be tested on their…… [Read More]

Nursing Healthcare Information Systems Key

Others include delays in data accessibility, albeit shorter delays and the continued need for source data verification (Donovan, 2007).

Other obstacles have occurred in the developing of mobile healthcare applications. These have included mobile device limitations, wireless networking problems, infrastructure constraints, security concerns, and user distrust (Keng and Shen, 2006).

A third problem that has been encountered is that of a lack of education on not only the importance of the information technology but also training on how to use the specific pieces of equipment. The tools that are provided to people are only as good as the training that is provided on how to use them. The tools may be able to do wonderful things, but if those that are using them do not know how to get the best use out of them they will in the end be less efficient.

Affect of Tylenol Overdose on the Cardiopulmonary System

Tylenol Overdose

Health Sciences 101

The Health Impact of Acetaminophen Overdose

Acetaminophen (APAP) is a common over-the-counter (OTC), antipyretic, anti-inflammatory, analgesic that is more commonly known as Tylenol®, a product of Johnson & Johnson1. Overseas the drug is called paracetamol and is manufactured and sold by countless generic drug makers.

A number of concerns regarding the safety of APAP have arisen over the past several years, including liver and kidney toxicity and adverse cardiovascular and cardiopulmonary effects. This essay will provide an overview of APAP, its uses, and safety issues, with an emphasis on the cardiopulmonary system.

Mechanisms of APAP Activity

The analgesic and antipyretic activity of APAP was thought to be similar to other non-steroidal anti-inflammatory medications because it was believed to inhibit prostaglandin (PGE2) synthesis2,3. This assumption has not withstood the test of time, for either APAP or other popular OTC non-steroidal anti-inflammatory drugs (NSAIDs). The main evidence…… [Read More]

health care system delivery with other nations (European/Canada) with emphasis on its relative strengths and weaknesses?

Michael Moore's Sicko reveals that nearly 50 million U.S. citizens are not insured, whereas many usually fall prey to insurance firm red tape and frauds. Interviews are carried out with individuals believed to be sufficiently covered; in truth, these individuals do not receive health services at all. Ex-workers of insurance firms explain cost-cutting efforts which provide insurance firm physicians and other individuals with excuses to avoid fulfilling the costs of policy holders' essential medical treatments, thereby increasing the companies' profitability (Heart, 2012).

The documentary-maker then moves over to Canada, where he introduces Tommy Douglas, the man voted in 2004 as the best Canadian citizen for the role he played in improving the nation's healthcare structure. The director interviews a Canadian micro-surgeon and emergency room patients at a public hospital in Canada. His interviews in…… [Read More]

Nursing Related Case Study Tom's Vitals in

Nursing elated Case Study

Tom's vitals, in the emergency department, revealed an elevated respiratory rate, heart rate and blood pressure. His oxygen saturation was also considerably low. Tom's Body Mass Index (BMI) falls in the overweight category. He was also a-febrile, at presentation, indicating that infection was not a precipitating cause.

Initially the ABGs were normal, indicating an acute severe exacerbation or life threatening asthma. Later, when the ABGs were repeated, carbon dioxide levels were above normal. A raised carbon dioxide level is the differentiating bench mark between life threatening and near fatal asthma. The ABG analysis also reveals acidemia which cannot be solely attributed to a respiratory or metabolic cause alone, and hence can be safely classified as a mixed disorder.

Tom's history is typical of atopic asthma which usually begins in childhood and is triggered by antigens from the environment, such as pollen, animal dander or dust. Upper…… [Read More]

Living Things Are Characterized by the Following

living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant kingdom (ex, plants take in carbon dioxide and prepare their own food), these characteristics are commonly observed among all living things.

iology is a very broad field that encompasses the study of characteristics of living things. It includes botany, zoology and all other sub-disciplines that range from microbiology to evolution and ecology.

Evolution is the branch of biology that deals with the study of natural development of living organisms and the changes in them over time. Evolution refers to the heritable changes that occur in a population over a period of time. All the diversity that is observed currently in plant and animal kingdom can be ascribed to evolution over a long period of time.

Causes of Chronic Bronchitis in Workers

This review shows the literature and research available in the issue of respiratory diseases and the various occupations. The review shows that there is a pressing need to evaluate and conduct research in the known areas like coal, cement, and pesticides, but alarmingly agriculture and other industries have also to be included.

It is not only the factories that are hazardous. There are arguments to show that even farming can cause allergies. osenman (2012) in viewing "respiratory hazards that farmers and family members" argues that the grains that can be "contaminated with fungi, bacteria or microbial toxins; pesticides; solvents; gasoline and diesel fuels; and irritant gases such as oxides of nitrogen and ammonia." This may lead to occupational asthma and the allergens in such cases could be grain dust, cow dander, cow urine, egg yolk proteins, alternaria, aspergillus, cladosporium, meal worm, poultry mites, fungi,…… [Read More]

Lungs What Are the Lungs

However, it was 1953 that the formation of serotonin was from the lungs was substantiated. It is also observed that detoxification of the blood takes place in the lungs. Later, it was observed that one of the important activities of the lung is to provide chemical filtration by shielding the regular circulation of blood from the attack of vasoactive mixtures and other exogenous compounds present in the arteries. The physiology of the lungs and its location makes the lung exclusively suitable to perform these activities. (Wet; Moss, 1998)

The total output from the cardiac system is obtained by the lungs whereas other organs acquire only a very small quantity of output. The blood that circulates the lungs is subject to the vast capillary endothelial plane of the body which is of seventy square meters. This aspect of output and circulation enable the lung to perform the efficient function of biochemical…… [Read More]

Scientific Effects of Smoking on the Human

scientific effects of smoking on the human body especially on the respiratory and cardiovascular systems. We will give a brief analysis on how smoking affects the mentioned systems and see how the human body system works if the individual does not smoke. We will also support our paper with scientific and statistical evidence regarding the facts related to smoking.

Smoking and its effects

Before looking at smoking and its effects lets review on how the respiratory and cardiovascular systems work. When we breathe air it first enters Trachea/windpipe through which it enters on each of the bronchi present at both of the lungs. The bronchus is spread throughout the lungs like branches on trees and at its tips is as thin as a hair (bronchioles). Each lung has about thirty thousand bronchioles. At the tip of every bronchiole lies an area which leads to tiny air sacs known as alveoli.…… [Read More]

Case Study and Nursing

Advance Nursing Practice

In order to sustain life, the human body has to have oxygen. When a person cannot breathe, or there is not enough oxygen coming into the body through the act of breathing, it is not possible for life to continue. The respiratory system is what provides the person with the opportunity to breathe and take in oxygen. Carbon dioxide is also expelled that same way. If oxygen is not received, the brain cells will start dying, followed by other cells, organs, and tissues. Addressed here is a case study dealing with the respiratory system, conditions it may face, and how those issues can be treated.

The Breath of Life

Throughout scripture the concept of breath represents life. Genesis 2:7

It is evident that we need to breathe to live and that without our respiratory system, we would die. But why is this? Can we know why other than to say that this is how our Creator designed us to be? Perhaps an understanding of our own respiratory system can help us to better understand our Creator? I think so.

What do we find in our nose? A kind of filter that keeps out of our lungs harmful particles and spores that would otherwise pollute them. This can be a symbol of how we should filter our minds of impure thoughts so as to keep our souls clean. It can also be a symbol of how important God's grace is in our souls -- it is to our souls as oxygen is to our bodies.…… [Read More]

Structures often play the important role when a building is on fire. Upon many reviews, there are a lot of fires claiming for lives of the inhabitants of the building, but there are also some cases, which had taken the firefighters' lives as well. Such cases should not have happened, but limited information of the building's structures and length of fire could have caused it.

Chesapeake automobile warehouse happened to be a fatal case of fire (NFPA, 2002). The 12-year-old building was constructed under lightweight wood trusses. There were two steel frames and another brick construction located at the building. The trusses were built using the combination of wood and metal plates that joined them altogether.

On Monday morning, March 18, 1996, the repair shop operated as usual. The employees were coming along to start their first day of the week, taking up service…… [Read More]

Diagnosis and Treatment of TB

Tuberculosis

Causative agent

Tuberculosis is an infectious disease of animals and humans. The most common causative agent of the disease is a bacterium a mycobacteria known as Mycobacterium tuberculosis. This bacterium was first discovered by obert Koch in 1882. The physiology of this bacterium is aerobic and hence requires very high oxygen levels. This is primarily a pathogen of the mammalian respiratory system which infects the lungs. The most common methods used to diagnose tuberculosis are acid-fast stain, tuberculin skin test and chest radiations. M. tuberculosis requires oxygen in order for it to grow. Due to the presence of mycolic acid, M.tuberculosis has an waxy coating on its surface which is unusual making the cells impervious to Gram staining It can not retain any bacteriological stain as a result of a high lipid content on its wall therefore acid-fast staining or ziehl-Neelsen staining are used. Despite this M.tuberculosis is still…… [Read More]

Adrenal Gland Keeping the Body

S. Congress that the prospects of stem cell research were so vast that it could touch all the realm of medicine (Connor 2000). An unlimited source of embryonic stem cells will solve the problem of shortage of transplants. Embryonic stem cells will save lives by curing generative diseases of the brain, hepatitis, diabetes, leukemia, rheumatoid arthritis, muscular dystrophy and cystic fibrosis and diseases of the heart and kidneys. ut current laws restrict the use of stems cells on embryos less than 14 days old and for correcting fertility, reproduction or congenital disorders. The restriction is grounded in the belief that the embryo is a potential human being from the moment of conception. It thus possesses a soul and a dignity just like any other viable person (Connor). Previous scientific research presented evidence that genetically engineering cells could partly repair a defective immune system (Travis 2002). Two new studies bolstered this…… [Read More]

Weapons of Mass Destruction Wmds

By continuing with a "business as usual" attitude, the terrorists would not have a long-term psychological impact on American society, culture and economic development.

hile the long-term psychological impact appears to be the most prominent value that a weapon of mass destruction has for a terrorist, it seems reasonable to argue that these weapons also serve as a means for terrorist groups to have their political voices heard. Terrorist attacks bring to light the activities, beliefs and values of a specific terrorist group. Although many in the U.S. were familiar with Osama bin Laden before 9/11, his implication in the terrorist attacks made him and Al-Qaeda household names. In this context, bin Laden was able to bring to light the organization's hatred of the United States and the organization's political agenda for the entire international community. The publicity gained from terrorist events clearly has value for terrorist groups.

Public Awareness and Human Diseases

A way to better distribute the information that is being taught in the classrooms is also through the community so that the changes are also effecting the parents to the students, as a change on their part as well would be helpful in the battle against obesity. It would be useful to initially target pamphlets, an informational booth or table at grocery stores, where the foundation of the problem lies. It would be effective if information is given before families go grocery shopping so they are more conscious of the items that they are purchasing. Furthermore, information should also be initially presented on TVs, in newspapers and magazines and other mediums that would likely be used in the more low-key and sedentary setting in order to galvanize individuals to get outside. Once outside, in order to sustain the physical activity, it would be nice to have water and juice at…… [Read More]

Contingency Management Alcohol & Marijuana

" (1995)

The authors state: "The amphetamines occasioned dose-related increases in d- amphetamine-appropriate responding, whereas hydromorphone did not. Amphetamines also occasioned dose-related increases in reports of the drug being most like "speed," whereas hydromorphone did not. However, both amphetamines and hydromorphone occasioned dose-related increases in reports of drug liking and in three scales of the ARCI. Thus, some self-report measures were well correlated with responding on the drug-appropriate lever and some were not. Lamb and Henningfield (1994) suggest that self-reports are complexly controlled by both the private event and the subject's history of experience with the drug. Some of the self-reports they observed (e.g., feels like speed) are probably occasioned by a relatively narrow range of stimuli because in the subject's experience with drug administration, these reports have been more selectively reinforced by the verbal community relative to other reports (e.g., drug liking). They also suggest that these results imply…… [Read More]

Michael Lauren Who Is Struggling With Drug

Michael Lauren who is struggling with drug problem. Michele Lauren is twenty-one-year-old girl, single and a resident of New York City. Michele lives with her parents and is addicted to marijuana. She was arrested on various circumstances, each time for the violation of Health & Safety Code 11357 (Samaha, 2007) that is the possession of large quantity of drugs and was locked up behind the bars on trials during the years 2002 to 2008.

Lately, she had been arrested three times in a month for the violation of such law. Michele had also encountered the problem of alcohol along with her problem of smoking pot and marijuana, but she has not been arrested for excess drinking and violation of Health and Safety laws related to alcohol. She had not been arrested for any other related crimes, as she normally filched her mother's purse for money whenever needed.

Nursing and Issue of Falls Are Responsible

Nursing and Issue of Falls

Falls are responsible for considerable morbidity, immobility, and mortality among older persons, especially those living in nursing homes. Falls can occur in a home, community, long-term rehabilitation, or acute care Setting (Laurence Z.. et.al, 1994). The risk of falls can be related mostly to mobility status, exposure to hazardous environments and risk-taking behaviors such as climbing ladders for seniors living in the community setting. Factors for a fall in hospitalized adults are greatly influenced by acute illness that often has a marked, albeit temporary, impact on physical and cognitive function compounded by care provided in unfamiliar surroundings in the long-term care setting, the risk factors for falls are influenced by impaired cognition, wandering or impulsive behavior, use of psychotropic medications, incontinence and urgency, lack of Exercise, unsafe environments, and low staffing levels. Patient falls are serious problems

In acute care hospitals and are used as…… [Read More]

Influence of Mean Airway Pressure on Cardiovascular Performance

Airway Pressure on Cardiovascular Performance

HEART-LUNG CONNECTION

The Influence of Mean Airway Pressure on Cardiovascular Performance

reathing, also known as pulmonary ventilation, is the basic connection between the heart and lungs (Williams & Whitney, 2006). The connection allows air between the lungs and the atmosphere and the exchange of gases between the air and the alveoli in the lungs. ody receptors can detect changes involved in the movement of air and the pressure that accompanies it. These receptors can either increase or decrease breathing rate. They encourage slower breathing when blood pressure rises and faster breathing rate if the blood pressure goes down. Meanwhile, an exchange of gases between body tissues and capillaries is needed to maintain life. It brings in the gases living tissues need for survival. lood carries oxygen molecules when leaving the heart and distributes it throughout the body. Very small capillaries coordinate in the flow and…… [Read More]

Mold Spore Analysis and Toxicity

Mold Spore Trapping

Current Scientific Knowledge

People are exposed to aeroallergens in a variety of settings, both at home and at work. Fungi are ubiquitous airborne allergens and are important causes of human diseases, especially in the upper and lower respiratory tracts. These diseases occur in persons of various ages.

Airborne spores and other fungi particles are ubiquitous in nonpolar landscapes, especially amongst field crops, and often form the bulk of suspended biogenic debris. The term mold often is used synonymously with the term fungi. A more precise definition would specify that molds lack macroscopic reproductive structures but may produce visible colonies. Respiratory illness in subjects exposed to rust and dark-spored imperfecti fungi was described more than 60 years ago, and physicians worldwide now recognize a sensitization to diverse fungi.

Since fungus particles commonly are derived from wholly microscopic sources, exposure hazards are assessed largely through direct sampling of a…… [Read More]

Harmful Health Effects of Chronic

"The IOM report recognized the therapeutic benefits of medical marijuana and urged that marijuana be made available to individual patients while research continued on the development of new drugs developed from marijuana" (Zeese).

Conclusion

In conclusion, there are two schools of thought on this issue. One view sees very little difference in terms of health implication between marijuana and cigarette smoking. However, there is some resistance to the idea that marijuana is as unhealthy or as dangerous as cigarettes. This had led to the notion that marijuana is less harmful to the user than tobacco. However, many reports and studies tend to stress that while the effects of each substance on the individual differ, in the long - term both have negative effects that should be emphasized. (Vlahov et al., 2004)

While there is a strong case for the benefits of marijuana in certain instances and for certain conditions, this…… [Read More]

Neurofibroma Genetic Traits and Impact

However, recently, anesthesiologists have suggest a low to mid thoracic epidural combined with adequate general anesthesia. This anesthetic technique will allow for adequate inter-operative monitoring. After the operation, the anesthesiologist must continue to monitor the patient for either hypertension, hypotension and hypoglycemia. The presence of either of these conditions may alter the course of the medication given to the patient once the patient is removed from the anesthesia.

Respiratory System

Neurofibroma can cause systemic problems within the various components of the Respiratory System. As has already been presented, Neurofibromas can cause partial blockages within upper parts of the trachea. However, Neurofibromas can also pose challenges or the anesthesiologist when dealing with nasal, sinus or maxilofacial cavities with Neurofibromas present within. One example of how devastatingly complex the Neurofibroma can become is seen when a benign neurofibroma can cause a superior vena cava compression. Such was the case of a 21-year-old…… [Read More]

" (Murphy, 2009)

This is held by Murphy to be what is wanted since high carbon dioxide levels help to maintain high quality silage." (2009) Simultaneously, the gas that is "odorless and colorless" is stated to be that which is dangerous. The gas is stated to replace the oxygen in the silo and since this gas is present in high concentrations the individual receives very little in the way of warning that the gas is about to overcome them. This gas is stated to be characterized by "…a strong bleach-like odor and low lying yellow, red, or dark brown fumes. Unlike carbon dioxide, nitrogen dioxide levels reach a peak about three days after harvesting and rapidly begin to decrease thereafter particularly is the silo is ventilated." (Murphy, 2009)

Sealed silos are specifically designed so that there is no necessity to enter them however, there are various gases present in convention…… [Read More]

Mold Assessment and Indoor Exposure

quality of indoor air has received and increasing amount of attention, including a large amount of discussion about sick building syndrome, which has been recognised since the 1970's. Certainly, most North Americans spend the majority of our lives indoors, and the quality of our indoor air environment has been shown to play a huge role on our health. A wide variety of indoor pollutants can have an effect on human health, including environmental tobacco smoke, volatile organic chemicals (VOCs) and biological pollutants. iological indoor pollutants include dust mites, cockroaches, effluvia from pets like birds, rodents, dog and cats and mold.

Early investigations into sick building syndrome often gave a multi-factorial explanation for the symptoms of occupants. However, these investigations often could not explain the long duration of effects. Further, investigations into indoor air quality have historically ignored the problem of mold, and failed to give a clear history of water…… [Read More]

Microbial Volatile Organic Compounds as Indoor Air Pollutants

Air pollution pertains to substances and gases in the air that threaten health and life. Among these are pollutants and irritants, such as nitrogen oxides, sulfur dioxide, and carbon dioxide; particulates, volatile organic compounds (VOCs), toxic substances and some natural substances, like pollen. ut most of the pollution comes from the by-products of industrialization - fossil fuel combustion, transportation, transportation, power plant emissions and those from other industrial processes. The burning of fossil fuels to generate electricity alone is the greatest source of air pollution in the U.S.A. These outdoor pollutants can undermine health and cause environmental disturbances, such as acid rain, and are toxic.

Studies show that we now spend more than 90% of our lives inside buildings and other constructed environments. ecause of this, such structures - including homes and office buildings - are constructed with energy efficiency and comfort foremost in mind. The installation of central heating,…… [Read More]

Benefits After Quitting Smoking

enefits After Quitting Smoking

Among the many health risks that toll life, smoking is considered as the most preventable cause of mortality. Globally, smoking has been one of the principal factors that lead to diverse type of diseases, such as cancer, coronary heart disease, lung disease, and many others. The number of smokers worldwide grows everyday, both in developed and developing countries. According to Karl Fagerstrom's Epidemiology of Smoking, from a 1995 estimate, the rate of smoking-related mortality will grow from 3 million to 10 million annually by 2030.

In response to the risks that smoking causes to the increasing number of smokers', many health organizations worldwide conduct different programs that are hoped to minimize and prevent people from smoking. This includes the provision of enough information on the effects of smoking to one's health, as well as information on how to quit from the smoking habit.

Physiological Effects of Endurance Training

Physiological Effects of Endurance Training

Endurance training produces many physiological changes, both during training and after the training period is complete. These changes are biochemical and also involve changes in the cardio-pulmonary system. The correct way to perform endurance training has been a subject of controversy in recent years. There are many differences in training methods. These differences and the effects of endurance training will be the subject of this research. The jury is still out as to what constitutes the perfect duration and intensity of training program.

Studies have shown that a focused training program can increase maximum oxygen intake by 15-30% over a three-month period (7) and that can increase to 50% if the training is sustained for over 2 years. The body makes many metabolic adaptations as well. These adaptations drop rapidly in the first few weeks after training is stopped (1).

Anesthesia Means Temporary Loss of

In year 1799 anesthetic properties of Nitric Oxide were discovered by Humphery Davy (1778-1829) he advised that the by using nitric oxide, pain and shock of the surgical procedure can be negated. Third person who continue with Morton and ells philosophy was Charles T. Jackson. The Fourth man who contributed to anesthetics was Thomas Mortan (Blatner, 2009). In the year 1848 James Simpson used chloroform in obstetric surgery, he used diethyl ether to anesthetize a women with a pelvic deformity for delivery (kodali, 2009) and in year 1853 John Snow did a successful induction of chloroform to her Majesty Queen Victoria at the time of Prince Leopold's Birth and also on Fenny Longfellow who wrote to her poet brother that this use of ether is certainly the greatest blessing of this era (Longfellow, 1956). In the year 1885-illiam Halsted introduced the nerve block. In 1891 Heinrich Quincke demonstrated the process…… [Read More]

Tourism in Southeast Asia Since SARS Outbreak

2003 was marked by a number of natural disasters throughout the world, but none more devastating and threatening than the outbreak of a new virus now known as SARS. In this paper, I will focus primarily on the economic affect of the disease to the tourism industry in Southeast Asia. I argue that the magnitude of the affect SARS had on the tourism industry is attributable to three factors: the nature of the virus, the reaction by World Health rganization officials, and finally, the inadequacy in which local governments (specifically the Chinese) handled the epidemic. Finally, I will touch on the affects SARS has had on the tourism industry thus far, and its future implications.

In order to understand the effects of SARS in the world economic climate, specifically that of tourism, it is important to explore the disease itself. SARS (Sever Acute Respiratory Syndrome) is a form of pneumonia…… [Read More]

Confined Space Electrodes Chromium

Confined Space, Electrodes, Chromium

Confined spaces

A confined space is an enclosed or partially enclosed space that is not primarily designed or intended for human occupancy, it has a restricted entrance or exit by way and size, fined spaces as well poor ventilation. Confined spaces can be below or above ground, it can be found in almost any workplace. A confined space, despite its name, is not necessarily small. Examples of confined spaces include silos, vats, hoppers and utility vaults.

The AS defined confined spaces as having limited space and modes of ingress and egress as well as poor ventilation (American elding Society, 2003a). hile the NIOSH defined confined spaces as sufficient space enough for a person to enter and conduct work, limited means of entry and exit, and does not suit continuous employment. The AS definition is more restricted than that of the broader (Hammer & Price, 2001).

Vertebrates

It is common knowledge that the human body consists of about 65% water. People cannot live any longer than five days without H20. Individuals of all ages love to sail the oceans, swim in the sea and soar under or speed across the waves. It comes as no surprise, then, that some part of the human psyche remembers millions and millions of years ago before animals came on shore. What is still questionable is how or why these animals made the move from water to land. The journal articles discussed below give some of the latest findings on this topic.

Early in the Devonian Era, close to 400 million years ago, all the continents were grouped closely together and surrounded by the seas. The climate ranged from dry weather to torrential rains as some tropical areas do today. Even flowers had not yet evolved on land, let alone vertebrates.…… [Read More]

Military Retirees Are Entitled to

First of all only a scant few of these Veterans groups will acknowledge the "promise" of free health care; for the most part these groups will tout the benefits already promised by the Veterans Administration and assert that cuts in these benefits are the same a broken promise-or contractual breach in legal terms. The idea of the United States military making a "promise" or forging a legally binding agreement between individual veterans or groups of veterans is barred by the United States Constitution. As will be demonstrated in the Literature eview, specific Constitutional language from Article I give Congress and only Congress the express authority to make laws and regulations pertaining to the armed forces. Therefore, the idea the military breached a contract with service members is, ultimately, inherently inaccurate. Combining the lack of specific language within the materials provided by any governmental agency with the clear language of the…… [Read More]
