Experiment HC-2

For all questions, show results from the data (means, standard deviations, statistical tests and/or graphs) to justify your answers.  Explain what the results mean.  If the results differ from what you might have expected, discuss the reasons.

Exercise 1: Measuring Blood Pressures

Lab data exercise 1

Use the data to compare the resting systolic pressure, diastolic pressure, pulse pressure, heart rate between males and females. 

Exercise 2: Effects of Food Additives

Lab data exercise 2 

Questions

1 Are there any differences among your subjectís blood pressures and heart rates at different time intervals?

2 Check the data from other subjects. Which treatment caused the greatest percentage change in the subjectís blood pressure?

3 Which treatment caused the greatest percentage change in the subjectís heart rate?

4 What other results can you determine from the data?

Exercise 3: Effects of Exercise

Lab data  exercise 3

Questions

1 Compare the blood pressures before and after exercise. How long does it take your subjectís blood pressure to return to the resting level? How does the time it takes your subjectís blood pressure to return to normal compare to the times of other subjects?

2 Compare the heart rates before and after exercise. How long does it take your subjectís heart rate to return to the resting level? How does your subjectís recovery time compare to those of other subjects.

3  What other results can you determine from the data?

Exercise 4: Effects of Apnea

Lab data  exercise 4 

Questions 1 What effect does apnea have on the subjectís blood pressure?

2 How does the subjectís blood pressure change when the subject resumes breathing after apnea?

3  What other results can you determine from the data?

Exercise 5: Effects of Cooling the Forearm

Lab data  exercise5

Questions

1 By examining the pulse data during the cooling period, determine if cooling has any effect on pulse amplitude? Explain your conclusion.

2 Determine if cooling has any effect on heart? Explain your conclusion.

3 Determine if cooling has any effect on blood pressure? Explain your conclusion.

 

Exercise 6 : Effects of Warm ing the Forearm

Lab data  exercise6

Questions

1 By examining the pulse data during the cooling period, determine if warming has any effect on pulse amplitude? Explain your conclusion.

2 Determine if warming has any effect on heart? Explain your conclusion.

3 Determine if warming has any effect on blood pressure? Explain your conclusion.
