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 to a stimulus….
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 ten pounds;….
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 growth and….
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 inhalation and….
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 develop elongation or….
Case Study 1
Primary Diagnosis: Viral Pneumonia
Pneumonia, in basic terms, leads to the inflammation of the lung’s air sacs. It could be caused by a wide range of organisms such as fungi, viruses, as well as bacteria. Some key symptoms of pneumonia, according to the American Lung Association (2018), include but they are not limited to: “cough, which may produce greenish, yellow or even bloody mucus; fever, sweating and shaking chills, shortness of breath; rapid, shallow breathing; sharp or stabbing chest pain; loss of appetite, low energy, and fatigue; nausea and vomiting; confusion.” The symptoms Patient X (a 35-year-old Asian male) presents are consistent with the early symptoms of viral pneumonia. This is more so the case in reference to the mild intermittent fever, productive cough, and occasional nausea and muscle pain. It is also important to note that during examination, one is likely to identify rales and rhonchi amongst patients….
Structure and Function of the Respiratory System
Case
Forty-five-year-old Brad has, ever since the age of 20, been working in the mines in the post of coal cutter. He is happy with his job as he earns a good wage and his father also worked in the very same mine. Akin to several co-workers of his, he suffers from chronic cough. However, Brad has neglected going for yearly health checks as is required for mine workers owing to his fear of being diagnosed with “black lung” (i.e., coal worker pneumoconiosis). This ailment results in fibrosis, lasting dilation of the small airways, and reduced diffusing capability. At more advanced stages of the disease, alveoli, airways and pulmonary capillaries get destroyed.
Chronic obstructive pulmonary disease (COPD)
COPD has been described as a persistent inflammatory lung ailment which obstructs flow of air from the patient’s lungs. Disease symptoms include difficulties in breathing, wheezing, coughing, and sputum (or….
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 differentiate between….
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 and/or….
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….
Anatomy and Physiology of the Immune System and espiratory System and Their Associated DisordersThe human body is comprised of multiple important systems that keep people alive, including the immune and respiratory systems. These two systems in particular have received a great deal of attention in recent years due to their vulnerability to infections by the Covid-19 virus (Iwasaki & Wong, 2021), but there are a host of other disorders that adversely affect these systems as well. The purpose of this paper is to provide a description of the immune and respiratory systems and the respective physiologies of these two systems. In addition, the paper presents a description of the physiology of these two systems and some of the most common disorders that are associated with them, is followed by an integrative discussion concerning how these systems interact with each other and how they are dependent on each other for proper….

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 the number….

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 help….
Case Study eport of Eddie: Acute espiratory Failure with Underlying COPDToday, approximately 10% of all intensive care unit admissions as well as almost one-quarter (24%) of all patients that require mechanical ventilation, are due to acute respiratory failure (Parcha et al., 2021). The purpose of this case study report is to provide an assessment of Eddie, a 50-year-old male recently admitted to the intensive care unit with acute respiratory failure. The case study report begins by providing a brief description of acute respiratory failure, including its pathophysiology, subtypes, causes, and diagnostic criteria. The next section provides a critical analysis of Eddie\\\'s presentation on admission to intensive care, linking it to pathophysiology, physical assessment findings, and diagnostic tests, to arrive at a diagnosis of Eddie\\\'s acute respiratory failure. In addition, the case study report evaluates and describes the ventilation-perfusion (V/Q) mismatch that was identified in Eddie\\\'s diagnosis. In addition, an interpretation….
