On Line Lab/ Blood Pressure Experiment
The virtual Blood Pressure Experiment consisted of five (5) groupings of male subjects and five (5) groupings of female subjects. The groupings were broken down into age brackets of 11-17, 18-24, 25-34, 35-44, and 45-54 years of age.
The purpose behind Oxygen/Circulation/Immunity: Online Lab for Human Biology was to show that I had gained knowledge about taking a persons pulse, blood pressure/hypertension, and also the factors that can lead to and cause hypertension.
From a web site I looked at (listed below)
http://www.disabled-world.com/artman/publish/bloodpressurechart.shtml
I learned a wealth of information about blood pressure. I found out that there are many indicators and factors leading to a person having high blood pressure. Long term (chronic) high blood pressure is called, “hypertension”. Hypertension can damage blood vessels, lead to heart attacks and strokes.
Some of the most common factors are, age, obesity (30%) over ideal weight, alcohol consumption, sodium intake, lack of exercise, too much stress, smoking, heredity, gender, and race. Some of these items are completely out of a persons control, however, the good news is that many of these factors are decided by the persons choices! Things such as exercise, alcohol consumption, smoking, sodium intake, and obesity, are all results of our lifestyle and choices.
This piece of information is especially important because the items we can not change CAN be influenced in a positive direction by the factors we DO have control over. By this I mean that I can not change my family history of high blood pressure or my age of 47, however, I can choose to exercise, and maintain my weight within healthy guidelines, I can choose to NOT smoke, and also watch my sodium intake. The choices that I make, and the steps that I take, (literally) to help my blood pressure stay in the normal range can at least help to stabilize or balance out the “not in my control” factors.
Normal Blood Pressure - Blood pressure reading below 120/80 is considered normal.
High Blood Pressure - Blood pressure of 140/90 or higher is considered high blood pressure. If one or both numbers are usually high, you have high blood pressure.
Below are the journal questions from the lab write-up virtual experiment:
Q#1-State a problem about the relationship of age and gender to blood pressure.
The relationship of age and gender can be problematic to blood pressure in the following way; As a person ages whether they are male or female, on an average, their blood pressure has a natural tendency to increase on both the systolic (top) and the diastolic (lower) numbers of the blood pressure.
Q#2- Use your knowledge about the heart and the circulatory system to make a hypothesis about how the average blood pressure for a group of people would be affected by manipulating the age and gender of the group members.
- My hypothesis is that as a person ages, regardless of their gender, there is a good possibility that blood pressure will increase. Men have a higher risk of hypertension than women, however, as stress factors continue to escalate for females in today’s world, they too have higher health risks regarding blood pressure, heart attacks and strokes. The average blood pressure for a specific group of people will be affected by the natural signs of aging in the body. As men age they generally do not fair as well as females when looking at high blood pressure averages. Men may also make much less healthy choices as far as food/nutrient intake and life style choices, such as alcohol consumption, smoking, and not enough exercise. The choices made throughout the years directly affect the heart and the circulatory system. High cholesterol, plaque build up in the circulation system and sedentary life style influence blood pressure. The key factor I think is obesity, which is heavily influenced by the amount of exercise and food intake (caloric) choices.
Q#3-How will you use the investigation screen to test your hypothesis?
I will pay close attention to the blood pressure increase between both the male and the female subjects as the age brackets increase. I will also pay attention to the “factors” that are common on the individual persons chart to figure out what the commonalities are.
What steps will you follow?
I will look at the health risk factors that can be applied to each of the subjects that have hypertension in my experiment. I also want to look closely at any subjects with high blood pressure who only have, “Family History” as a health risk factors to be listed.
What data will you record?
I will follow age and gender first. I will look for weight within optimal range. I will look for family history and also “life choices” to find any trends.
Q#4- Analyze the result of your experiment.
Explain any patterns you observed.
Men and women both show increases in blood pressure as they age. Women do not show the amount of average increase to the same level that males do in my experiment. Up until 17 years of age males and females are almost identical. Men seem to increase on the average earlier in the life cycle then females do. Women average closer in their systolic number until they reach the 44 year age group when they jump 9 points after that. Men’s systolic steadily increases throughout the five age groups with the biggest jump being to the 18-24 age group.
Q#5-Did the result of your experiment support your hypothesis? Why or why not? Based on your experiment what conclusion can you draw about the relationship of age and gender to group blood pressure averages?
I do think my hypothesis is supported by the outcome because I stated that on the average a person would experience higher blood pressure and that men more so than females. My conclusion is that age and gender do play definite roles in hypertension .
Q#6-During the course of your experiment, did you obtain any blood pressure reading that were outside of the normal range for the group being tested? What did you notice on the medical charts for these individuals that might explain their high reading?
Yes I did get reads that were outside of the normal range starting with males in the 35 + age groups and then in the females group 45+.
Q#7-List risk factors associated with the hypertension. Based al range.on your observation, which risk factor do you think is most closely associated with hypertension?
I got five (5) abnormal reads on males between ages 35-44 and then seven (7) abnormal males age bracket 45-54. I also found two (2) abnormal reads on females between the ages of 45-54. I found 5 of the males to have family history. One of the females as well. I also found obesity to be of medical note on eight (8) of the 12 males and on one of the females. On a total of 9 of 14 subjects that had hypertension, one of their health factors was “obesity”. I think that a person maintaining a healthy weight can be critical to high blood pressure. I found lack of exercise, alcohol consumption, and sodium intake on various subjects. Family history (hereditary) seems to be a strong indicator of hypertension.
Q#8-What effect might obesity have on blood pressure? Does obesity alone cause a person to be at risk for high blood pressure? What other factors, in combination with obesity, might increase a person's risk for high blood pressure?
Obesity affects a persons cardiovascular/heart system because of the over stress that the heart muscle has to tolerate. The circulatory system has to work harder to accomplish the same amount of product (output) which includes oxygen and other gases within the body in an overweight person. The persons entire body must work harder to keep up with the added strain. In one of my females the only warning factor was +41 lb.over optimal weight. In one of my men it appeared one of his factors was ‘race’ and he was also +43 lbs over optimal weight. I think obesity can be the cause of hypertension, but I think it is influenced by other influences such as sodium intake, lack of exercise, high caloric/fatty foods.
