1. What is Mean Arterial Pressure (MAP)?

Definition: MAP is the average arterial pressure throughout one cardiac cycle, crucial for organ perfusion.

Purpose: It provides a better indicator of perfusion to vital organs than systolic blood pressure alone.

2. How Does the Calculator Work?

The calculator uses the standard MAP 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 normal cardiac cycles.

3. Importance of MAP Calculation

Details: MAP is critical in medical settings to ensure adequate organ perfusion. Normal range is 70-100 mmHg.

4. Using the Calculator

Tips: Enter valid systolic and diastolic BP values (SBP ≥ DBP). Values must be positive integers.

5. Frequently Asked Questions (FAQ)

Q1: What does MAP indicate clinically?
A: MAP < 60 mmHg may indicate inadequate blood flow to organs, while > 100 mmHg may suggest hypertension.

Q2: Why is DBP weighted more heavily?
A: Because the heart spends more time in diastole (relaxation phase) than systole (contraction phase).

Q3: When is MAP most important?
A: Critical in ICU settings, surgery, and for patients with circulatory compromise.

Q4: How does heart rate affect MAP?
A: Tachycardia reduces diastolic time, potentially increasing MAP at the same BP values.

Q5: What's a normal MAP range?
A: Typically 70-100 mmHg, with 60 mmHg being the minimum for adequate organ perfusion.
