1. What is an Average Blood Pressure Calculator?

Definition: This calculator computes the average of multiple blood pressure readings following Canadian hypertension guidelines.

Purpose: It helps healthcare professionals and individuals track blood pressure trends over time for better hypertension management.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Readings are in mmHg format (systolic/diastolic)
• The average is calculated separately for systolic and diastolic values
• Only properly formatted readings (number/number) are included

Explanation: The calculator sums all valid systolic readings and divides by their count, and does the same for diastolic readings.

3. Importance of Average Blood Pressure Calculation

Details: According to Hypertension Canada, diagnosis of hypertension should be based on the average of multiple readings taken on different occasions.

4. Using the Calculator

Tips: Enter multiple blood pressure readings separated by commas (e.g., "120/80, 118/82, 122/78"). The calculator will ignore invalid entries.

5. Frequently Asked Questions (FAQ)

Q1: How many readings should I enter?
A: Hypertension Canada recommends at least 2-3 readings on 3 different occasions for diagnosis.

Q2: What format should the readings be in?
A: Use systolic/diastolic format (e.g., 120/80). Only numbers separated by a slash will be processed.

Q3: How does this follow Canadian guidelines?
A: The calculator implements the averaging method recommended by Hypertension Canada for clinical decision-making.

Q4: What's considered a normal average BP in Canada?
A: Generally, <120/<80 mmHg is normal, 120-129/<80 is elevated, and ≥130/80 may indicate hypertension.

Q5: Should I use home or clinic readings?
A: Both are valuable. Hypertension Canada recommends using home readings to confirm clinic measurements.
