MAP = (Systolic Blood Pressure + 2 × Diastolic Blood Pressure) ÷ 3
Use the systolic and diastolic values from the blood pressure reading
Multiply the diastolic pressure by 2
Add that result to the systolic pressure
Divide the total by 3
Example: 120/80 mmHg
MAP = (120 + 2 × 80) ÷ 3
MAP = (120 + 160) ÷ 3
MAP = 280 ÷ 3
MAP = 93.3 mmHg
