Pulmonary Vascular Resistance

Input:
Mean Pulmonary Artery Pressure
Left Atrial Pressure
Pulmonary Flow
Result:
PVR dynes-sec-cm-5
 
Decimal Precision:
PVR = 80 * ( MeanPulmonaryArteryPressure - LeftAtrialPressure) / PulmonaryFlow
  • In most cases Pulmonary Flow is equivalent to the cardiac output.
  • Normal PVR is approximately 67 +- 30 dynes-sec-cm-5.
