Blood flow: Mean Pulmonary Pressure (MAP) vs. Mean Systemic Pressure?
Why is that mean pulmonary pressure is 5x less than mean systemic pressure? How does the equation for flow, pressure, and resistance relate to this? (Flow = Pressure/Resistance)
Pulmonary blood pressure is 25/15 mmHg. Therefore mean pulmonary pressure is (25 + 15)/2 = 20 mmHg.
Systemic blood pressure is 120/80 mmHg. Therefore mean systemic pressure is (120 + 80)/2 = 100 mmHg.
Pulmonary blood pressure is 5 times less than systemic arterial blood pressure.
Note:- Pulmonary blood pressure is 15-25/8-15 mmHg and systemic blood pressure is 110-130/70-80 mmHg.
