What are the two major determinants of mean arterial pressure?
What are the two major determinants of mean arterial pressure?
- Blood volume and oxygen saturation
- Vascular elasticity and blood viscosity
- Heart rate and stroke volume
- Cardiac output and total peripheral resistance (correct)
Which formula calculates mean arterial pressure using blood pressure values?
Which formula calculates mean arterial pressure using blood pressure values?
- MAP = Diastolic BP + (Systolic BP - Diastolic BP) / 3 (correct)
- MAP = Diastolic BP + (Systolic BP + Diastolic BP) / 3
- MAP = Cardiac Output × Total Peripheral Resistance
- MAP = (Systolic BP - Diastolic BP) / 3 + Diastolic BP

Study Notes
Mean Arterial Pressure (MAP)
- Two major determinants of MAP are cardiac output and peripheral resistance
- MAP = Cardiac Output × Total Peripheral Resistance (TPR)
- Equation only represents the relationship between MAP and its determinants; actual MAP is calculated differently
- Actual MAP = (Systolic BP + 2 Diastolic BP) / 3
- Normal MAP is roughly 65-100 mmHg
- Current guidelines recommend targeting a MAP goal of 65 mmHg for adequate organ perfusion
