1. What is a Blood Pressure Average Calculator?

Definition: This calculator computes the average systolic and diastolic blood pressure from multiple readings according to American Heart Association standards.

Purpose: It helps individuals and healthcare professionals track blood pressure trends over time for better cardiovascular health monitoring.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• SBP — Systolic Blood Pressure (mmHg)
• DBP — Diastolic Blood Pressure (mmHg)
• n — Number of valid readings
• Σ — Sum of all readings

Explanation: The calculator averages all systolic readings separately from diastolic readings to provide accurate mean values.

3. Importance of Blood Pressure Averaging

Details: Multiple readings provide a more accurate picture than single measurements, helping to identify true hypertension and avoid "white coat syndrome" errors.

4. Using the Calculator

Tips: Enter comma-separated SBP and DBP readings from the same measurement sessions. Ensure equal numbers of readings for both values.

5. Frequently Asked Questions (FAQ)

Q1: How many readings should I provide?
A: The American Heart Association recommends at least 2-3 readings per session over several days for accurate averaging.

Q2: What's considered a normal average?
A: Normal is <120/<80 mmHg; Elevated is 120-129/<80; Hypertension is ≥130/≥80 (American Heart Association 2017 guidelines).

Q3: Should I include unusual readings?
A: Only include valid readings taken under consistent conditions (same arm, position, time of day).

Q4: How often should I calculate my average?
A: Weekly averages are recommended for monitoring, or as directed by your healthcare provider.

Q5: Does this replace medical advice?
A: No, this tool is for informational purposes only. Always consult a healthcare professional for medical decisions.
