What is Mean Arterial Pressure?
a. the average pressure exerted on arterial walls during the contraction of the left ventricle
b. the average pressure exerted on arterial walls during the rest phase between beats
c. the average workload of the left ventricle in correlation to myocardial oxygen uptake
d. the average pressure exerted throughout the entire cardiac cycle
Answer: d. the average pressure exerted throughout the entire cycle
Mean Arterial Pressure is the average pressure exerted throughout the entire cardiac cycle. This is reflective of the amount of force driving the blood into the body's tissues. Normal, healthy MAP at rest is about 93 mmHg.
