Question

How is PVR (pulmonary vascular resistance) determined?

Answer 1

PVR is calculated by the formulae:
`\text{Mean PVR}=\frac{\text{mean PAP-PAOP}}{\text{CO}} *80`

Step-by-step 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}} *80`

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