Enter the change in pressure across the circulation loop and the flow through the vasculature into the calculator to determine the TPR.

## TPR Formula

The following formula is used to calculate TPR (total peripheral resistance).

TPR = P / Q
• Where TPR is the total peripheral resistance
• P is the change in pressure across the circulation loop
• Q is the flow rate through the vasculature

To calculate TPR, divide the pressure change by the flow rate.

## What is TPR?

Definition:

TPR, short for total peripheral resistance, is a measure of the total amount of force exerted on circulating blood by the vasculature of the body.
