Our PVR Calculator helps healthcare professionals and students quickly determine Pulmonary Vascular Resistance (PVR), a crucial hemodynamic parameter. Understand its significance in assessing pulmonary hypertension and cardiac function with ease, utilizing key inputs like mPAP, PCWP, and Cardiac Output.
Formula:
Pulmonary Vascular Resistance (PVR) is calculated using the following formula:
PVR = (mPAP - PCWP) / CO
- PVR: Pulmonary Vascular Resistance (in Wood Units)
- mPAP: Mean Pulmonary Artery Pressure (in mmHg)
- PCWP: Pulmonary Capillary Wedge Pressure (in mmHg)
- CO: Cardiac Output (in L/min)
The result is typically expressed in Wood Units (WU) or dynes·s·cm-5 (by multiplying WU by 80).
