1. What is an Average Blood Pressure Calculator?

Definition: This calculator computes the average of multiple blood pressure readings taken over time, following American medical guidelines.

Purpose: It helps individuals and healthcare providers track blood pressure trends more accurately than single readings.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Avg BP — Average blood pressure (mmHg)
• Systolic — Upper number in BP reading
• Diastolic — Lower number in BP reading
• n — Number of valid readings

Explanation: The calculator averages all systolic readings separately from diastolic readings, following clinical best practices.

3. Importance of Average Blood Pressure

Details: Multiple readings provide a more accurate picture than single measurements, reducing "white coat hypertension" effects.

4. Using the Calculator

Tips:

• Enter at least 2 readings (more for better accuracy)
• Readings should be taken on different days
• Follow standard BP measurement protocols

5. Frequently Asked Questions (FAQ)

Q1: Why average multiple readings?
A: Single readings can be misleading due to daily variations. Averages provide more reliable data.

Q2: How many readings should I take?
A: American Heart Association recommends 2-3 readings per session, over multiple days.

Q3: What time of day is best for readings?
A: Take readings at consistent times, preferably morning and evening.

Q4: How do I interpret the results?
A: Compare to standard categories: Normal (<120/<80), Elevated (120-129/<80), Stage 1 (130-139/80-89), Stage 2 (≥140/≥90).

Q5: Should I discard any readings?
A: Only discard readings with obvious errors. The calculator handles normal variability.
