Which is an equation one can use to find cardiac output (CO) in a patient where you know the blood pressure (BP) and the peripheral vascular resistance (PVR)?

Question

Group of answer choices

CO = BP x PVR

CO = PVR/BP

CO = BP/PVR

CO = BP + PVR

Answer 1

The correct equation to find cardiac output (CO) using blood pressure (BP) and peripheral vascular resistance (PVR) is:

CO = BP / PVR

This relationship follows from the hemodynamic principle where cardiac output is proportional to the pressure gradient (blood pressure) and inversely proportional to the resistance (peripheral vascular resistance).
