MAP is a medical abbreviation with more than one meaning — most commonly Most commonly Mean Arterial Pressure. Its meaning depends on the clinical context.
What does MAP mean?
| Meaning | Context | Field |
|---|---|---|
| Mean Arterial Pressure | Critical Care and Cardiology | The average pressure in the arteries during one cardiac cycle, used to judge whether organs are being adequately perfused. A value of about 70 mmHg or higher is generally the target. It can be estimated as the diastolic pressure plus one third of the pulse pressure. |
| Mitogen-Activated Protein | Laboratory and Molecular Medicine | A type of protein involved in cell signaling, best known from MAP kinase pathways that regulate cell growth and response to stress. This meaning appears in research and pathology rather than at the bedside. |
Why it matters
At the bedside MAP almost always means mean arterial pressure. The mitogen-activated protein meaning appears in laboratory and research contexts.
Frequently asked questions
What does MAP stand for in medicine?
In clinical practice MAP most often means mean arterial pressure, the average pressure in the arteries during one heartbeat.
What is a normal MAP?
A mean arterial pressure of about 70 mmHg or higher is generally considered adequate to perfuse the organs.
How is MAP calculated?
A common estimate is the diastolic pressure plus one third of the difference between the systolic and diastolic pressures.
Does MAP have another meaning?
Yes. In laboratory and molecular medicine MAP can mean mitogen-activated protein, as in MAP kinase. Context tells you which is meant.
