Which of the following equations would you use to compute total peripheral resistance (CO = cardiac output)?

Question

Quizplus · Accepted Answer

The equation for total peripheral resistance is (mean aortic pressure - right atrial pressure) divided by cardiac output (CO). Therefore, choice C is the correct equation. Choice A is incorrect because it multiplies the mean aortic pressure and right atrial pressure together before dividing by CO. Choice B is incorrect because it multiplies the mean aortic pressure by the reciprocal of the right atrial pressure before multiplying by CO. Choice D is incorrect because it subtracts the mean aortic pressure from the right atrial pressure instead of vice versa.
