MAP Equation:
From: | To: |
Mean Arterial Pressure (MAP) is the average pressure in a patient's arteries during one cardiac cycle. It is considered a better indicator of perfusion to vital organs than systolic blood pressure alone.
The calculator uses the standard MAP equation:
Where:
Explanation: The equation accounts for the fact that diastole lasts longer than systole in the cardiac cycle, giving diastolic pressure more weight in the calculation.
Details: MAP is crucial for assessing blood flow, organ perfusion, and tissue oxygenation. It's particularly important in critical care settings and for patients with hypertension or hypotension.
Tips: Enter both diastolic and systolic blood pressure values in mmHg. Both values must be valid (greater than 0).
Q1: What is a normal MAP range?
A: Normal MAP is typically between 70-100 mmHg. Below 60 mmHg may indicate inadequate blood flow to organs.
Q2: Why is MAP important in medicine?
A: MAP is used to evaluate perfusion pressure and is critical for maintaining organ function, especially in critically ill patients.
Q3: How does MAP differ from blood pressure?
A: Blood pressure shows two values (systolic/diastolic) while MAP represents the average pressure throughout the cardiac cycle.
Q4: When is MAP most commonly used?
A: MAP is frequently monitored in ICUs, during surgeries, and when managing hypertensive or hypotensive patients.
Q5: Can MAP be too high?
A: Yes, elevated MAP (>100 mmHg) may indicate hypertension and increased cardiovascular risk.
