How to share home blood pressure readings with your doctor

A clinician can do more with a complete record than with a single number. Before an appointment, organise your readings so the timing, technique and context are visible.

Bring the original details

Include the date and time, systolic and diastolic readings, pulse if shown, arm used and notes about anything that changed your usual routine. Keep both readings if you measured twice rather than reporting only an average.

A CSV can make a long record easier to sort. The free blood pressure log template creates one in your browser, while the photo-to-CSV scanner can help if your readings are still stored as monitor photos.

Bring the monitor and cuff

If practical, take the monitor and cuff with you. Ask the clinician or pharmacist to check the cuff size, placement and device against their equipment. This can reveal a technique issue that numbers alone cannot show.

Explain the routine

Tell them:

• when you usually measure;
• how long you rest beforehand;
• whether you take one or two readings;
• which arm you use; and
• whether medication, illness, pain, caffeine, exercise or sleep changed around the log.

A short summary can point to the relevant part of a longer record, but do not discard the original rows. Patterns often make more sense with their surrounding context.

Questions worth asking

You could ask which arm to use, how often to measure, what range matters for your situation, and what action to take if a reading is unexpected. Ask how often your monitor should be checked too.

Do not stop or change prescribed medication because of a home log. If you feel seriously unwell or believe you may be experiencing a medical emergency, seek urgent local help.
