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
