## In brief: Resistance

For fixed cardiac output, BP will vary with peripheral vascular resistance, and vice versa.
The components are more complicated however.

## In brief: Mathematical

There is a standard equation which relates cardiac output to blood pressure and vascular resistance.
The lesion is q = (map – rap)/tpr where q = cardiac output, MAP = mean arterial pressure, RAP = right atrial pressure, and tpr = total peripheral resistance (also called systemic vascular resistance).
