Where:
Explanation: The calculator sums all valid readings and divides by the number of days with valid data (up to 10).
Details: The UK NHS recommends monitoring BP over time rather than relying on single readings for accurate diagnosis of hypertension.
Tips: Enter your systolic blood pressure readings for each day (mmHg). Leave blank any days without readings.
Q1: Why 10 days specifically?
A: 10 days provides a balance between getting enough data for accuracy while being practical for home monitoring.
Q2: What time of day should I measure?
A: UK guidelines recommend morning and evening measurements, but be consistent with timing.
Q3: Should I include all readings?
A: Include typical readings but exclude measurements taken during acute illness or stress.
Q4: What's a healthy average BP?
A: Generally below 135/85 mmHg at home (equivalent to 140/90 in clinic), but consult your GP.
Q5: What if I have fewer than 10 readings?
A: The calculator will average whatever readings you provide (minimum 3-4 recommended).
