A useful log helps turn individual readings into a pattern your healthcare professional can review.
Record more than one number
Include the date, time, systolic value, diastolic value, and pulse. Add which arm you used and whether the reading was first or second in the session. If your monitor syncs to an app, check that timestamps are correct.
Add short context notes
Examples include missed medication, pain, illness, poor sleep, caffeine, exercise, or a stressful event. Keep notes brief so patterns are easy to scan.
Bring the monitor to an appointment
Ask whether to bring your device and cuff for a technique or comparison check. Never change medication based only on a home log unless the prescribing clinician tells you to.
If a reading is unusually high or low, follow the plan your healthcare professional has given you. Seek urgent help for severe symptoms or when advised by local emergency guidance.
