1. What is a Blood Pressure Calculator?

Definition: This calculator determines the average blood pressure and mean arterial pressure (MAP) from systolic and diastolic readings.

Purpose: Helps medical professionals and individuals assess cardiovascular health and perfusion pressure.

2. How Does the Calculator Work?

The calculator uses two formulas:

Where:

• Systolic — Maximum arterial pressure (mmHg)
• Diastolic — Minimum arterial pressure (mmHg)
• Avg BP — Simple average of both pressures
• MAP — Mean arterial pressure, weighted average

Explanation: MAP accounts for the fact that the heart spends more time in diastole, giving diastolic pressure more weight.

3. Importance of Blood Pressure Calculation

Details: MAP is particularly important as it represents the average pressure driving blood to tissues throughout the cardiac cycle.

4. Using the Calculator

Tips: Enter systolic and diastolic values (both must be > 0). Normal MAP range is 70-100 mmHg.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between Avg BP and MAP?
A: Avg BP is a simple average, while MAP weights diastolic pressure more heavily to reflect actual perfusion pressure.

Q2: Why is MAP important?
A: MAP determines whether organs receive adequate blood flow. Below 60 mmHg may indicate inadequate perfusion.

Q3: What's a normal MAP value?
A: Typically 70-100 mmHg. Below 60 may be concerning, while above 100 may indicate hypertension.

Q4: Can I calculate MAP if I only know Avg BP?
A: No, MAP requires knowing both systolic and diastolic values separately.

Q5: How often should MAP be monitored?
A: In critical care, continuously. For general health, during routine blood pressure checks.
