MAP Calculator
This tool quickly calculates mean arterial pressure (MAP) using your systolic and diastolic blood pressure. It's used in clinical practice to gauge whether organs are getting enough blood flow.

How to Use the Calculator
- Enter the systolic blood pressure (SBP).
- Enter the diastolic blood pressure (DBP).
- Instantly see your MAP result.
What the MAP Result Means
Mean arterial pressure (MAP) is the average pressure in the arteries over one heartbeat. It indicates how well blood is flowing to vital organs (perfusion). Clinicians often aim for a MAP of about 65 mmHg or higher to ensure organs are adequately perfused.
When to Use This Calculator
- Organ perfusion assessment
- ICU/emergency monitoring
- Hypotension and shock evaluation
Frequently Asked Questions
What is a normal MAP?
In adults, a normal mean arterial pressure is roughly 70–100 mmHg. Clinicians typically consider around 65 mmHg the minimum needed for adequate organ perfusion.
What does low MAP indicate?
A low MAP indicates that organs may not be receiving enough blood flow. It often points to hypotension or shock.
Is MAP the same as blood pressure?
No. MAP is derived from systolic and diastolic pressures but is not the same as a routine blood pressure reading. It represents the average arterial pressure during one heartbeat, rather than the separate systolic and diastolic values.
