How to Use the Mean Arterial Pressure (MAP) Calculator
- Enter Systolic BP (top number, e.g., 120) in mmHg.
- Enter Diastolic BP (bottom number, e.g., 80) in mmHg.
- Click "Calculate MAP".
Result: MAP = (2 × Diastolic + Systolic) ÷ 3. A normal MAP is 60–100 mmHg.
Both values must be non‑negative numbers. Use whole numbers or decimals.

Frequently Asked Questions
MAP is the average pressure in a patient's arteries during one cardiac cycle. It is considered a better indicator of perfusion to vital organs than systolic blood pressure alone.
MAP is calculated using the formula: MAP = (2 * Diastolic Pressure + Systolic Pressure) / 3. This formula emphasizes the diastolic phase, which is longer.
A normal MAP typically ranges from 70 to 100 mmHg. Values below 60 mmHg may indicate inadequate perfusion, while values above 100 mmHg may indicate hypertension.
