blood pressure will be affected by drinking a large, caffeinated coffee.
The researcher believe caffeine does have some kind of an effect on a persons' blood pressure, for the reason that we recognize that Caffeine is a drug that is naturally produced in the seeds and leaves of a lot of plants. It's similarly made artificially and added to definite foods. Caffeine is defined as a drug for the reason that it arouses the central nervous system, producing increased attentiveness. Caffeine provides most individuals a temporary energy boost. Which is lactated in coffee, tea, chocolate, numerous energy drinks.
Why was the patient's blood pressure recorded before he drank the coffee?
One of the reasons why it was recorded was because he wanted to measure the blood pressure at various time points using a home blood pressure monitor. It was important to record it before they drank the coffee because that way they will know rather or not it went up or down after they drank it and then recorded it again.
Question 3: From the data presented in the previous slide, draw conclusions about the effects of caffeine on blood pressure.
From the data that is shown in the slide, the conclusion that cab be drawn that the coffee did not have that much effect on the individual blood pressure even though it did go up some towards later parts of the day. However, there was a slow elevation in the patients' blood. Despite caffeine's probable elevation in the person's diastolic blood pressure, it is a possible fact that the person's automatic nervous system could have brought the heart rate to maintain only a little increase in the total cardiac activity when it is linked to the resting outcomes after taking in the coffee. They subject seemed to deviate a little somewhat from the resting systolic blood pressure values, despite the fact showing a rise in diastolic pressure and a reduction in heart rate. It can also be concluded from the graph that the caffeine-induced blood pressure changes were actually quite small and really short-lived. It is obvious from the graph that is shows that caffeine does not give to conditions of the blood vessels connected with high blood pressure.
Questions 4 and 5: Would these conclusions be considered as a possible basis for a theory? Explain your answer
Yes, these conclusions could be considered the possible foundation for a theory because in people with normal blood pressure, it seems that caffeine could possibly cause some kind of a temporary increase in blood pressure according to this research. This is for the reason that caffeine is considered to be a vasoconstrictor which is saying that it can thin blood vessels. Part of the theory could also be said that some people actually develop a tolerance to coffee, and then in the end it may no longer has this effect. For example, in the experiment, the blood went up only slightly been then after that it went steady for the rest of the time being monitored. Nonetheless in particular, it is significant to recognize that there is no indication that caffeine can be the root high blood pressure, likewise acknowledged as hypertension.
However, this experiment does not take in the account of an individual that has high-normal blood pressure or diagnosed hypertension, so there is nothing to compare this subject with. However, part of the theory with this person can be concluded that caffeine appears to increase their levels to a much bigger degree than those with readings that are normal. As a result, it could possibly be concluded that an individual who has hypertension should try to evade coffee.
Question 6: What would the null hypothesis for the experiment presented on the previous slide?
The null hypothesis for the experiment presented on the previous slide would be that there is no effect of caffeine on a person's blood pressure after consumption one time and it being monitored throughout the day.
Question 7: From the data presented in the previous slide, draw conclusions about the effects of smoking on blood pressure.
From the data presented, it is clear that smoking does have an effect on the blood pressure mainly with the diastolic pressure. It also appears that throughout the day, it still went up even with the diastolic pressure. The interesting thing about this study is that it showed that even when they stopped the smoking the blood seemed to go up more with the diastolic pressure and sort of stay at an even flow with the systolic pressure but did seem to go up really high at the start of the smoking but actually as time went on, went down and almost back to the way it was before the experiment even started. However, diastolic pressure or systolic seem to go back down to the normal pressures that were before the experiment actually began.
It is clear the graph that cigar smoking has quite of an effect on the blood pressure but it seems to have the greatest effect on the diastolic pressure more than it does on the systolic. The graph shows that the experiment started at 10:56 and ended at 12:16 so that is exactly one hour and thirty three minutes. In that time frame, it can be concluded that cigar smoking seems to cause the blood pressure to go up rather quickly, especially for the diastolic pressure.
Question 8: What are the problems/limitations with this experiment?
The conclusions that were reached in both experiments are basically done by using one subject in each case so there are no other subjects to compare the results. Using just one person in these experiments sort of gives it a general statement because we are unaware of other factors in each subject. For example, we have no idea rather or not they are man or woman. Because caffeine and smoking effect each sex differently. Other problems and limitations are the fact that we are unaware about the subject's health or even age. Both of these would play a huge factor in these experiments and by not knowing either, can cause the results to be a little biased or even skewed. There is also other information that is not mentioned in the experiment which would make it very limited and that is things like rather or not they are healthy from the start and even things like family background. Where they work and if they are married or even I there are things like mental health issues in the family.
For example with the caffeine and its effect on blood pressure, there are possible limitations because if the person did have some kind of a disease, then there should have been a documentation of the effects of caffeine for let us say for instance the subject used had hypertension, so that is saying that the documentation would need to be done in order to examine its presser effects on individuals at various levels of risk for the disease. Another limitation for instance for the cigar effect on blood pressure was that not enough time was given or even the subject did not want to finish out the experiment. In that case, the result collected can only be analyzed for the time it has recorded which means that there may or may not have been enough time for the experiment to have gotten much more results. Maybe two or more hours would have given even a more accurate measure. The same could be said with caffeine and its effect on the blood pressure. Time was short in collecting data, and even though it did not show much of a difference, who knows if the experiment had of been any longer, what the results could have been. With that said, time could…
