If a person has a systolic pressure of 140 mm Hg and a diast

If a person has a systolic pressure of 140 mm Hg and a diastolic pressure of 90 what is the mean arterial pressure? Pulse pressure? How does the pressure in capillaries compare to the pressure in arteries? Why is this important in the scheme of things? Are veins high or low-pressure vessels, and why? How does the pressure in the aorta compare the vena cavae?

Solution

Answer : Question number 38 :

Given : Systolic pressure = 140 mm Hg

Diastolic Pressure = 90 mm Hg

The Mean arterial pressure(MAP) can be calculated using the formula

Systolic pressure + 2 (diastolic pressure) / 3

so, MAP = 140 + 2 (90)/3

= 140 + 180 / 3

Mean arterial pressure = 106 mm Hg
