thoscope were first cleaned with the alcohol swabs. The diaphragm was then placed on the bicuspid area to hear the heart sounds. Also, the diaphragm was placed on the aortic and pulmonic areas. During these three auscultations, the heart sounds were compared during quiet breathing, slow and deep inhalation, and slow exhalation. The results were recorded. Focus was then switched to blood pressure. The subject sat on a chair with their left arm resting on a table. The blood pressure cuff was wrapped just above the elbow. The diaphragm of the scope was then placed at the site on the cuital fossa where the arterial pulse was felt. The valve was screwed shut and the pump pressure was pumped until no sounds were heard. The screw was slightly loosened allowing the air to slowly come out. The first sound (systole) was recorded and when the sound disappeared Cardiac Physiology 6(diastole). This was done during three different times. Once while the subject was in four positions: standing, reclining, sitting down, and after five minutes of motionlessness. These values were recorded. The pulse pressure was calculated (systolic diastolic). Using this value, the mean arterial pressure was calculated (diastolic + 1/3 pulse pressure). The values were recorded. Sticking with the theme of blood pressure individuals pulses were taken. One extra piece of material was needed which was an 18 high chair. The subject laid flat and then counted their pulse for thirty seconds. This number was multiplied by two and recorded. Immediately standing up, the subject took their pulse in the same manner. The difference of the two was noted. Next the subjects stood up on an 18 high chair and lowered themselves five times. Upon completing their pulse was taken for 15 seconds and multiplied by four. This value was recorded. Successively, the pulse was taken for 30, 60, 90, and 120-second increments. These were also recorded. The normal pulse ...
