Mean Arterial Pressure
93.3 mmHg
Normal (60–100 mmHg)
Mean Arterial Pressure (MAP) is the average arterial pressure throughout one cardiac cycle. It represents the true perfusion pressure driving blood to vital organs.
- 1MAP = (SBP + 2×DBP) / 3
- 2Alternative: MAP = DBP + (SBP − DBP)/3
- 3Normal MAP: 70–100 mmHg
- 4MAP < 60 mmHg: inadequate organ perfusion (emergency)
SBP 120 mmHg, DBP 80 mmHg=MAP = (120 + 2×80) / 3 = 280/3 = 93.3 mmHg (Normal)
| MAP (mmHg) | Status | Clinical meaning |
|---|---|---|
| < 60 | Critical low | Organ perfusion compromised |
| 60–70 | Low normal | Marginal — monitor closely |
| 70–100 | Normal | Adequate organ perfusion |
| > 100 | Elevated | Hypertension risk |
