About MAP Calculator
When to Use
- To assess tissue perfusion
- In critical care settings
- During shock management
- For cerebral perfusion assessment
- In trauma and resuscitation
Pearls/Pitfalls
- Normal MAP is typically 70-100 mmHg
- MAP <65 mmHg suggests inadequate organ perfusion
- Consider patient-specific targets
- Values may vary with position and measurement site
- Not a standalone indicator of tissue perfusion
Why Use
- Quick assessment of perfusion pressure
- Guides resuscitation efforts
- Helps monitor treatment response
- Better indicator than systolic pressure alone
- Essential for critical care management
About MAP
Mean Arterial Pressure
MAP represents the average arterial pressure during a single cardiac cycle. It is considered a better indicator of tissue perfusion than systolic blood pressure alone.
Formula: MAP = [(2 × Diastolic) + Systolic] ÷ 3
Alternative: MAP ≈ Diastolic + ⅓(Systolic - Diastolic)

MAP Interpretation Guide
| MAP Range | Interpretation | Clinical Significance |
|---|---|---|
| <65 mmHg | Low | Risk of organ hypoperfusion |
| 65-70 mmHg | Borderline | Monitor closely |
| 70-100 mmHg | Normal | Adequate perfusion |
| >100 mmHg | Elevated | May indicate hypertension |
