Hemodynamics, Dr. D. Penney



Peripheral Resistance Units (continued..)

Used Clinically:

SVR = 80 (AOm - RAm) / Qs

PVR = 80 (PAm - LAm / Qp


Where: AOm, RAm, PAm, & LAm are the aortic, right atrial, pulmonary artery, left atrial mean pressures in mmHg, Qs & Qp are systemic and pulmonary blood flows in liters/min.

* 80 is factor converting R from mmHg/liter/min to dynes-sec-cm-5
