\/>\r\n<\/section><br \/>\nPulmonary Vascular Resistance (PVR) reflects the resistance that the right ventricle must overcome to pump blood through the pulmonary circulation. Elevated PVR is often associated with pulmonary hypertension and heart failure. It\u2019s calculated using hemodynamic measurements from right heart catheterization. A normal PVR is typically < 3 Wood units (or < 240 dyn\u00b7s\/cm\u2075). This calculator simplifies the computation and provides quick results for clinicians.\n\n\n<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This Pulmonary Vascular Resistance (PVR) calculator estimates the resistance offered by the pulmonary vasculature using mean pulmonary artery pressure (PAP), pulmonary capillary wedge pressure (PCWP), and cardiac output (CO).
