Frequently Asked Questions
Why is MAP important?
It is considered a better indicator of organ perfusion than systolic blood pressure alone.
What is a normal MAP?
Between 70 and 100 mmHg is considered normal for most adults.
How is it used in the ICU?
Nurses and doctors use MAP to titrate life-saving medications (vasopressors) to keep the pressure high enough to protect the brain and kidneys.
