Pulmonary Vascular Resistance (PVR) Calculator - MDApp
This Pulmonary Vascular Resistance (PVR) calculator determines vascular resistance based on pressure difference and blood flow in pulmonary circulation. ... Normal values: Mean Pulmonary Arterial Pressure: mmHg, cmH2O, kPa, atm or psi: ... Lower than normal PVR is most commonly caused by dysfunction in one of the following: calcium channel ...

Physiology, Pulmonary Vascular Resistance - StatPearls - NCBI Bookshelf
A normal value for pulmonary vascular resistance using conventional units is 0.25 to 1.6 mmHg·min/l. Pulmonary vascular resistance is also represented in units of dynes/sec/cm-5 (normal = 37dynes/sec/cm-5 to 250 dynes/sec/cm-5). Poiseuille’s law has been used to model PVR (see Image. Poiseuille's Law Modeling Pulmonary Vascular Resistance).

Pulmonary Resistance - QxMD
Normal PVR is 30 - 90 Dynes.sec.cm-5 or 0.5-1.1 Wood Units and TPR is 150-250 Dynes.sec.cm-5 or 1-3 Woods Units. Increased PVR can be seen with hypoxia, hypercapnea, increased sympathetic tone, polycythemia, precapillary pulmonary edema, pulmonary emboli, or lung compression (pleural effusion) and in ventilated patients. ...

Post-Void Residual Urine Test: Levels & Results - Cleveland Clinic
What’s a normal post-void residual volume? Results of a post-void residual test report the amount of pee left in your bladder, or PVR volume. A normal post-void residual volume is between 50 mL (milliliters) and 100 mL. Your provider might consider different PVR volumes high or abnormal for you. They’ll explain what your results mean.
