Which of the following equations best depicts the factors determining mean arterial blood pres-sure?

a. Mean arterial pressure = cardiac output vascular resistance
b. Mean arterial pressure = cardiac output vascular resistance
c. Mean arterial pressure = right atrial pres-sure aortic pressure
d. Mean arterial pressure = vascular re-sistance cardiac output

Question 2

Which of the following statements is true?

a. Pulmonary vascular resistance (PVR) is equal to systemic resistance.
b. Pulmonary vasculature is a high-pressure, high-resistance circulation.
c. Systemic vascular resistance (SVR) is less than PVR.
d. SVR is normally approximately 10 times higher than PVR.

Answer to Question 1

ANS: B
Average blood pressure in the circulation is directly related to both cardiac output and flow re-sistance.
Mean arterial pressure = cardiac output vascular resistance.

Answer to Question 2

ANS: D
