Mean Arterial Pressure Calculator
Calculate Mean Arterial Pressure from systolic and diastolic readings
About this calculator
The Mean Arterial Pressure (MAP) Calculator determines the average pressure in your arteries during one cardiac cycle. MAP is a critical indicator of tissue perfusion and cardiovascular health, helping healthcare professionals assess blood flow to vital organs. This calculator uses the standard formula: MAP = Diastolic Pressure + (1/3 × Pulse Pressure), providing quick and accurate results for medical monitoring and clinical decision-making.
How to use
Enter your systolic blood pressure (the higher number when your heart beats) and diastolic blood pressure (the lower number when your heart rests) in the input fields. Click calculate to instantly get your Mean Arterial Pressure value, which represents the average pressure throughout your cardiac cycle.
Frequently asked questions
What is a normal MAP range?
A normal MAP typically ranges from 70-100 mmHg. Values below 60 mmHg may indicate inadequate organ perfusion, while values above 100 mmHg suggest hypertension.
Why is MAP more important than systolic/diastolic alone?
MAP better reflects tissue perfusion pressure because it accounts for the time spent in diastole, providing a more accurate assessment of cardiovascular health.
How is MAP calculated?
MAP is calculated using the formula: Diastolic Pressure + (1/3 × Pulse Pressure), where pulse pressure equals systolic minus diastolic pressure.
