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 the heart spends more time in diastole than systole, giving diastolic pressure more weight in the average.
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 systolic and diastolic blood pressure in mmHg. The systolic value must be higher than the diastolic value for accurate calculation.
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 particularly important in managing shock, hypertension, and during surgical procedures.
Q3: How does MAP differ from blood pressure?
A: While blood pressure shows systolic and diastolic values separately, MAP represents the average pressure throughout the cardiac cycle.
Q4: When is MAP most commonly used?
A: MAP is especially important in intensive care units, during anesthesia, and when monitoring patients with circulatory problems.
Q5: Are there other ways to calculate MAP?
A: An alternative formula is MAP = (SBP + 2×DBP)/3, which gives similar results to the standard formula.
