Why is MAP important?

MAP reflects organ perfusion better than systolic blood pressure alone.

MAP Calculator – Mean Arterial Pressure

Q: What happens if MAP is low?

Low MAP can result in poor organ perfusion and shock.

Systolic BP (mmHg)

Diastolic BP (mmHg)

What is Mean Arterial Pressure?

Mean Arterial Pressure (MAP) represents the average pressure in arteries during one cardiac cycle and reflects tissue perfusion.

Normal MAP

70–100 mmHg – Adequate perfusion

Mean Arterial Pressure (MAP) Calculator

Mean Arterial Pressure (MAP) is a critical hemodynamic parameter that represents the average blood pressure in the arteries during one cardiac cycle. It is widely used in ICU, anesthesia, and emergency medicine to assess organ perfusion.

What is Systolic Blood Pressure (SBP)?

Systolic blood pressure is the pressure exerted on arterial walls when the heart contracts and pumps blood into circulation. It is the top number in a blood pressure reading and reflects cardiac output and arterial stiffness.

What is Diastolic Blood Pressure (DBP)?

Diastolic blood pressure is the pressure in the arteries when the heart relaxes between beats. It reflects peripheral vascular resistance and coronary artery perfusion.

How to Calculate MAP?

MAP is calculated using the formula:

MAP = (SBP + 2 × DBP) ÷ 3

A MAP of at least 65 mmHg is generally required to maintain adequate organ perfusion, especially in critically ill patients.

MAP – Frequently Asked Questions

What is a normal MAP?

Normal MAP ranges from 70 to 100 mmHg in healthy adults.

Why is MAP more important than BP?

MAP better reflects tissue perfusion than systolic blood pressure alone.

What happens if MAP is low?

Low MAP may result in inadequate blood flow to vital organs and can lead to shock.
