An important vital signfor monitoring human health is blood pressure.In particular, doctors want to know what the pressure of a patient's blood is as it passes through the heart.
a. What are the two separate fluid systems when a cuff is used measure a person's blood pressure. Are the two systems connected, and if so, how?
b. Using a cuff around the upper arm, why is blood pressure measured with the person sitting upright?
c. Suppose you want to measure the blood pressure of aperson,and for whatever reason (perhaps due to injury), you are not able to use an upper arm of the person to measure the blood pressure, so you have to use a leg instead.In what position would you place the person before making the measurement?Why?
d. Assume that you measured a patient's blood pressure on the patient's leg while the patient was sitting up.How would you determine the pressure at heart level?
