Physiology, Pulmonary Vascular Resistance - StatPearls - NCBI Bookshelf

Pulmonary vascular resistance (PVR) is the resistance against blood flow from the 4 pulmonary veins of the lung to the left atrium. It is most commonly modeled using a modification of Ohm’s law (see Image. Pulmonary Vascular Resistance Derived from Ohm's Law). Input pressure represents the mean pulmonary arterial pressure (15 mm Hg). The output pressure represents the pulmonary venous ...

Pulmonary vascular resistance index: Getting the units right and why it ...

Abstract. Pulmonary vascular resistance (PVR) and PVR index (PVRI) are key variables in a broad range of contexts, including prediction of outcomes in heart and liver transplantation, determining candidacy for closure of atrial or ventricular septal defects, and guiding treatment of pulmonary hypertension.

As such it is more precise at assessing the presence and degree of pulmonary vascular disease. 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, ...

Physiology, Pulmonary Vascular Resistance - PubMed

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).
