1. What is Mean Arterial Pressure (MAP)?

Definition: MAP is the average arterial pressure throughout one cardiac cycle, systole and diastole.

Purpose: It's a better indicator of perfusion to vital organs than systolic or diastolic blood pressure alone.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ MAP = DBP + \frac{SBP - DBP}{3} \]

Where:

Explanation: The formula accounts for the fact that the heart spends more time in diastole than systole.

3. Importance of MAP Calculation

Details: MAP is crucial in critical care settings to ensure adequate organ perfusion. Normal MAP is between 70-100 mmHg.

4. Using the Calculator

Tips: Enter both systolic and diastolic blood pressure values in mmHg. SBP must be greater than DBP.

5. Frequently Asked Questions (FAQ)

Q1: Why is MAP important?
A: MAP determines whether organs receive enough blood flow. Below 60 mmHg may lead to organ ischemia.

Q2: What's a normal MAP range?
A: Typically 70-100 mmHg. Below 60 is generally considered inadequate for organ perfusion.

Q3: Why divide by 3 in the formula?
A: This accounts for the approximate 2:1 ratio of time spent in diastole versus systole during the cardiac cycle.

Q4: How often should MAP be monitored?
A: In critical care, continuously. For general health, during routine blood pressure checks.

Q5: Can MAP be too high?
A: Yes, consistently high MAP (>100 mmHg) may indicate hypertension and increased cardiovascular risk.
