Tips:
Q1: How many readings should I enter?
A: For reliable averages, enter at least 7-14 readings taken over 3-7 days.
Q2: Should I include abnormal readings?
A: Include all readings unless you know they were measurement errors, as they reflect your true BP variability.
Q3: What time of day should I take readings?
A: Take readings at consistent times, especially morning and evening, before medication if applicable.
Q4: How does home BP compare to clinic BP?
A: Home readings are typically 5-10 mmHg lower than clinic readings due to "white coat effect."
Q5: 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.
