Blood Pressure Average Formula:
From: | To: |
Definition: This calculator computes the average of multiple home blood pressure readings.
Purpose: It helps individuals track their blood pressure trends over time by calculating mean systolic and diastolic values.
The calculator uses the formula:
Where:
Explanation: The calculator sums all systolic values and divides by the count, and does the same for diastolic values.
Details: Regular home BP monitoring provides a more complete picture of blood pressure than occasional clinic measurements, helping detect hypertension and assess treatment effectiveness.
Tips: Enter multiple BP readings in "Systolic/Diastolic" format (e.g., 120/80), one per line. For best results, use readings taken at consistent times of day over several days.
Q1: How many readings should I enter?
A: For reliable averages, enter at least 12-14 readings taken over 3-4 days (morning and evening).
Q2: What's a normal home BP average?
A: Generally, average home BP should be below 135/85 mmHg, but consult your doctor for personal targets.
Q3: Should I include all my readings?
A: Include all readings unless you have a specific reason to exclude some (e.g., measurement error).
Q4: How does home BP compare to clinic BP?
A: Home BP is typically 5-10 mmHg lower than clinic BP due to "white coat effect."
Q5: When should I be concerned about my average?
A: Consult your doctor if your average is consistently above 135/85 or below 90/60 mmHg.
