Question

the best estimate of map is
multiple choice
an arithmetic mean of systolic and diastolic pressures.
the difference between systolic and diastolic pressure.
the diastolic pressure plus one - third of the pulse pressure.

Explanation:

The mean arterial pressure (MAP) is best estimated as the diastolic pressure plus one - third of the pulse pressure. Pulse pressure is the difference between systolic and diastolic pressures. The arithmetic mean of systolic and diastolic pressures is not the best estimate of MAP. The difference between systolic and diastolic pressure is just the pulse pressure, not MAP.

Answer:

C. the diastolic pressure plus one - third of the pulse pressure.
