WebThe normal relationship between mean P pa and P la is described by the PVR equation rearranged as: mean P pa =PVR×Q+P la, where Q is pulmonary blood flow. The inherent assumptions of the PVR equation are that the TPGT–Q relationship is linear, crosses a zero pressure/zero flow value, and is, therefore, independent of the absolute value of P la.
