1. Note the difference in systolic pressure value between when (a) the sound actually began, (b) was detected by the stethoscope transducer, and (c) was recorded, and the time when the observer first heard the sound and pressed the event marker keystroke. (Example: 141 mmHg – 135 mmHg = 6 mmHg.) What factors could account for this difference? Would the observed difference be the same if measured by another observer? Explain your answer. 2. Do both systolic and/or diastolic pressure change as your heart rate increases? 3. How does this change affect your pulse pressure? 4. Define the first and second sounds of Korotkoff. Which sound is used to approximate systolic pressure and which sound is used to approximate diastolic pressure?

The traditional method of measuring blood pressure uses a sphygmomanometer, first recording the highest (systolic) and then the lowest (diastolic) pressure from which flowing "Korotkoff" sounds can be heard. Patients with dangerous hypertension can exhibit systolic pressures as high as 5 lbf/in'. Normal levels, however, are 2.7 and $1.7 \mathrm{lbf} / \mathrm{in}^{2}$ respectively, for systolic and diastolic pressures. The manometer uses mercury and air as fluids. (a) How high in cm should the manometer tube be? (b) Express normal systolic and diastolic blood pressure in millimeters of mercury.

You wish to determine the blood pressure at the top of a patient's head while they are standing. You measure the blood pressure in the patient's arm at the level of the heart and find that the systolic pressure is 120 mm Hg and the diastolic pressure is 80 mm Hg (760 mm Hg = 101 kPa). a) Blood pressure is usually measured with a pressure cuff around the arm at the level of the heart while the patient is sitting upright. Explain why this is good practice. b) What would be the diastolic pressure (in SI units) at the top of the patient's head, 50 cm above the measurement point? Assume a blood density of 1060 kg/m3. c) State whether this is a gauge pressure or an absolute pressure and explain your answer.

1. What is blood pressure? 2. What is the pulse? 3. If a person’s blood pressure is 155/90, identify the following: a. What is the value for the systolic pressure? What event in the heart cycle does the systolic pressure correspond to? b. What is the value for the diastolic pressure? What event in the heart cycle does the diastolic pressure correspond to?
