1. What is Mean Blood Pressure Calculation?

Definition: This calculator computes the average blood pressure according to UK clinical guidelines by analyzing multiple readings over time.

Purpose: Helps healthcare professionals and patients determine a reliable average blood pressure for clinical assessment and hypertension management.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Mean BP} = \frac{\text{Sum of Readings}}{\text{Number of Days}} \]

Where:

Separate averages are calculated for systolic and diastolic pressures
Readings should be taken under consistent conditions (same time of day, rested)
UK guidelines recommend measurements over 3-7 days for accurate assessment

Explanation: The calculator processes each valid reading (in mmHg format: systolic/diastolic) and computes separate averages for systolic and diastolic pressures.

3. Importance of Mean Blood Pressure

Details: Calculating mean blood pressure helps:

Reduce the impact of temporary fluctuations
Provide a more accurate picture of cardiovascular health
Guide treatment decisions for hypertension
Meet UK NICE guidelines for blood pressure monitoring

4. Using the Calculator

Tips:

Enter readings in "systolic/diastolic" format (e.g., 120/80)
Include multiple readings (minimum 3 days, ideally 7 days)
Take readings at the same time each day, after resting
Avoid entering readings taken during illness or unusual stress

5. Frequently Asked Questions (FAQ)

Q1: How many readings should I provide?
A: UK guidelines recommend at least 3-7 days of readings (twice daily) for accurate assessment.

Q2: What's considered a normal mean blood pressure?
A: Generally below 135/85 mmHg for home readings (UK guidelines).

Q3: Should I include all readings or just some?
A: Include all valid readings unless there was a clear measurement error.

Q4: How does this differ from clinic measurements?
A: UK guidelines recognize home measurements are typically 5-10 mmHg lower than clinic readings.

Q5: When should I seek medical advice?
A: If your mean blood pressure is consistently above 135/85 mmHg, consult your GP.
