How the Mean Arterial Pressure Calculator works
MAP = (systolic + 2 × diastolic) ÷ 3. It estimates the average pressure that pushes blood to your organs during one heartbeat. Pulse pressure is systolic minus diastolic. This tool is for information only; ask a clinician to interpret your readings.
Inputs and results
The Mean Arterial Pressure Calculator takes 2 inputs and gives 3 results.
What you enter
- Systolic pressure (mmHg) — starts at 120.
- Diastolic pressure (mmHg) — starts at 80.
What you get
- Mean arterial pressure
- Pulse pressure
- Compared with the usual range
Example: Mean Arterial Pressure Calculator with the starting values
With systolic pressure 120 mmHg and diastolic pressure 80 mmHg, the calculator returns:
| Mean arterial pressure | 93.3 |
|---|---|
| Pulse pressure | 40 |
| Compared with the usual range | Within 70 to 100 mmHg |
Change any value above and the results update straight away.
