Introduction:
Purpose: The purpose of this experiment was to determine how different variables may affect arterial pressure and pulse rate. Two subjects were used as models for the tests. The first two tests required the use of sphygmomanometers and stethoscopes to measure the arterial pressure and pulse rate. The last test required sphygmomanometers, plethysmographs, and the iworx system. Postural change was used as the variable in the first test to examine the changes of arterial pressure and pulse rate in subject 1. The next test included exercise as the variable. Subject 2 was required to have their resting blood pressure and pulse rate measured after performing an exercise. …show more content…

Exercise: Subject 2 was required to perform the step up exercise for five consecutive minutes. The subject’s blood pressure and pulse rate was measured immediately after the workout, one minute after the workout, two minutes after the workout, and three minutes after the workout. Cognitive Stress Test: Subject 1 had their baseline blood pressure and average pulse rate measured with the iworx system. This test required the subject to spell 15 words forward (task A) and 15 other words backward (task B) while having their blood pressure and pulse rate measured.
5 Discussion: Generally, most of the predicted baseline values were all wrong. The predicted baseline values that were used were calculated to be average values. The normal blood pressure is 120/80, which is why the average MAP value was chosen to be 93 mm Hg (80 + 40/3). The pulse rates were all within the normal limits depending on whether the subject was male or
