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 blood pressure alone.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( MAP \) — Mean Arterial Pressure (mmHg)
• \( SBP \) — Systolic Blood Pressure (mmHg)
• \( DBP \) — Diastolic Blood Pressure (mmHg)

Explanation: The formula accounts for the fact that diastole lasts twice as long as systole in a normal cardiac cycle.

3. Importance of MAP Calculation

Details: MAP is crucial in clinical settings to ensure adequate organ perfusion. A MAP of at least 60 mmHg is necessary to perfuse coronary arteries, brain, and kidneys.

4. Using the Calculator

Tips: Enter your systolic and diastolic blood pressure values in mmHg. SBP should be higher than DBP.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal MAP range?
A: Typically 70-100 mmHg. Below 60 mmHg may indicate inadequate blood flow to organs.

Q2: Why is MAP more important than blood pressure?
A: MAP better reflects the perfusion pressure throughout the cardiac cycle.

Q3: How is MAP used in medical settings?
A: Used to guide treatment in shock, hypertension, and during surgeries.

Q4: Can MAP be measured directly?
A: Yes, through arterial line monitoring, but this formula provides a good estimate.

Q5: What if my SBP is lower than DBP?
A: The calculator will show an error as this is physiologically impossible.
