1. What is Mean Blood Pressure?

Definition: Mean Blood Pressure (MBP) is the average pressure in a patient's arteries during one cardiac cycle.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The formula accounts for the fact that blood pressure spends more time near diastolic pressure than systolic pressure during the cardiac cycle.

3. Importance of Mean Blood Pressure

Details: MBP is crucial for determining tissue perfusion pressure. A MBP of at least 60 mmHg is necessary to maintain adequate perfusion of vital organs.

4. Using the Calculator

Tips: Enter both systolic and diastolic blood pressure values in mmHg. Systolic should be equal to or higher than diastolic.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal mean blood pressure range?
A: Typically 70-110 mmHg, but optimal range depends on individual health factors.

Q2: Why not just average SBP and DBP?
A: Blood pressure isn't a simple average - it spends more time near diastolic pressure during the cardiac cycle.

Q3: When is MBP particularly important?
A: Critical in managing shock, during surgery, and in intensive care settings to ensure organ perfusion.

Q4: How does MBP relate to MAP (Mean Arterial Pressure)?
A: MBP and MAP are often used interchangeably, though MAP may incorporate more complex calculations in some contexts.

Q5: What if my SBP is lower than DBP?
A: The calculator won't compute as this is physiologically impossible (systolic is always higher than diastolic in normal circumstances).
