If the mean pulmonary arterial and left atrial pressures are 20 and 8 mm Hg, respectively, and total blood flow is 5 L/min, what is the pulmonary vascular resistance?

Question

Quizplus · Accepted Answer

Pulmonary vascular resistance (PVR) = (mean pulmonary arterial pressure - mean left atrial pressure) / cardiac output
PVR = (20 mm Hg - 8 mm Hg) / 5 L/min
PVR = 12 mm Hg / 5 L/min
PVR = 2.4 mm Hg/L/min
