Accurately calculate Pulmonary Vascular Resistance (PVR) using mean pulmonary artery pressure (mPAP), pulmonary capillary wedge pressure (PCWP), and cardiac output (CO). Our PVR calculator helps assess pulmonary hypertension, providing quick results in Woods Units.
Formula:
The Pulmonary Vascular Resistance (PVR) is calculated using the following formula:
PVR = (mPAP - PCWP) / CO
Where:
- PVR = Pulmonary Vascular Resistance (expressed in Woods Units, WU)
- mPAP = Mean Pulmonary Artery Pressure (in mmHg)
- PCWP = Pulmonary Capillary Wedge Pressure (in mmHg)
- CO = Cardiac Output (in L/min)
Note: To convert Woods Units to dyn·s·cm⁻⁵, multiply the PVR result by 80.
