How is PVR (pulmonary vascular resistance) determined?
Alla [95]

Answer:

PVR is calculated by the formulae:  \text{Mean PVR}=\frac{\text{mean PAP-PAOP}}{\text{CO}} \times80

Explanation:

Pulmonary vascular resistance may be defined as the resistance to blood through the pulmonary circulation.  

PVR can be determined by the following formula:

\text{Mean PVR}=\frac{\text{mean PAP-PAOP}}{\text{CO}} \times80

Here, PAP is the pulmonary artery pressure, PAOP is pulmonary artery occlusion pressure and CO is cardiac output.
