How to keep a blood pressure log your doctor can use

A useful blood pressure log is more than a list of numbers. It connects each reading to a time, technique and small amount of context, so you and your healthcare professional can see what happened around it.

What to record

For every measurement, include:

• date and time;
• systolic and diastolic pressure;
• pulse, if your monitor displays it;
• which arm you used; and
• a short factual note when your usual routine was different.

Notes might include recent exercise, caffeine, smoking, poor sleep, pain or a cuff change. Avoid turning the log into a judgement about the number. The goal is a clear record.

Keep the routine consistent

Sit with your back supported, feet flat and arm supported at heart level. Use the correct cuff on bare skin, rest before measuring, and take the number of readings recommended by your healthcare professional. Consistency helps comparisons; it does not make a single reading diagnostic.

You can use the free blood pressure log template to create a CSV, or the average calculator to summarise a group while keeping the original rows.

Bring the record and the monitor

At an appointment, show the full log rather than only the highest or lowest values. Bring the monitor and cuff if possible. A clinician can compare the device with clinic equipment and check how you are applying the cuff.

Do not change medication based on a log without medical advice. If a reading is accompanied by serious symptoms or you think you may be experiencing an emergency, seek urgent local help.
