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 count, and does the same for diastolic values.
Details: Regular home monitoring provides more reliable data than occasional clinic measurements, helping detect hypertension and assess treatment effectiveness.
Tips: Enter your blood pressure readings (one per line) in mmHg format (e.g., 120/80). The calculator will ignore any invalid entries.
Q1: How many readings should I enter?
A: For accurate averages, enter at least 7-14 days of morning and evening readings (12-28 total).
Q2: What's considered a normal home BP average?
A: Generally, averages below 135/85 mmHg are considered normal for home measurements.
Q3: Should I include all my readings?
A: Yes, unless you know a reading was incorrect (e.g., during illness or right after exercise).
Q4: How does home BP differ from clinic BP?
A: Home readings are typically 5-10 mmHg lower than clinic measurements (white coat effect).
Q5: When should I consult my doctor?
A: If your average is consistently above 135/85 or you notice significant changes in your readings.
