WebMar 31, 2024 · A high PVR means a small run-off and a high pulmonary arterial compliance implies a large storage volume, both of which result in a small pulmonary pressure decrease in diastole. Practically we can characterize this decrease in pressure in diastole by measuring the exponential decrease with RC time as illustrated in Fig. 5.6 [ 31 ]. WebPVR may be higher than the SVR, allowing some degree of right-to-left shunting, until the SVR rises above PVR and blood flow is directed left to right.
