Cardiac output = SV x HR

Cardiac index = CO/BSA

Stroke volume index = SV/BSA

Mean arterial pressure = DP + (SP – DP)/3

Systemic vascular resistance = ((MAP – CVP)/CO) x 80

Systemic vascular resistance index = SVR/BSA

Pulmonary vascular resistance = ((PAP – PAWP)/CO) x 80

Pulmonary vascular resistance index = PVR/BSA
