Question

Mean arterial pressure (MAP) is determined by:

Answer 1

Answer:

Therefore, the mean arterial pressure is determined by e. cardiac output and b. resistance of the arterioles

Explanation:

Mean arterial pressure (MAP) is the average blood pressure of an individual during a particular cardiac cycle. It can be determined by cardiac output (CO), central venous pressure (CVP) and the systemic vascular resistance (SVR).

Therefore, the Mean arterial pressure can be calculated by:

systemic vascular resistance = (Mean Arterial Pressure - central venous pressure) / Cardiac Output

SVR= (MAP- CVP) / CO

or,

MAP = (CO × SVR) + CVP

Since, CVP is generally 0 mmHg, the equation can be simplified to:

MAP approx = CO × SVR
