Checking your blood pressure at home starts with more than pressing a button. Your cuff, sitting position, preparation, and recording routine all deserve attention.
This guide gives you a repeatable checklist to use alongside your monitor’s instructions and your healthcare professional’s advice. If you need help interpreting the display, read blood pressure readings explained.
1. Check Your Monitor and Cuff
Choose a validated automatic upper-arm monitor. Measure your upper arm and check that it falls within the cuff’s stated size range. Ask a clinician or pharmacist if you are unsure about suitability.
Before your first session, find the relevant pages in the instruction booklet:
- How to position and fasten the cuff.
- What the display symbols mean.
- How to retrieve stored readings.
- What to do if an error message appears.
Keep the booklet somewhere accessible. An unfamiliar symbol is a reason to check the instructions, rather than guess what the device is reporting.
2. Prepare Before Measuring
For 30 minutes beforehand, avoid exercise, caffeine, tobacco, and alcohol. Empty your bladder, then sit quietly for at least five minutes.
Avoid talking or using your phone during this rest period and the measurement.
A practical way to organise this is to put your monitor, notebook, and pen in place before sitting down. You can then complete the session without getting up to find something.
3. Set Up Your Sitting Position
Use this positioning checklist:
| Part of your setup | Position |
|---|---|
| Back | Supported by the chair |
| Feet | Flat on the floor |
| Legs | Uncrossed |
| Arm | Resting on a stable surface |
| Cuff | On bare upper-arm skin |
| Cuff height | At heart level |
Follow the manufacturer’s placement markings. Avoid a tightly rolled sleeve; remove your arm from the sleeve if necessary. A cushion may help support your arm at the right height.
Once the setup is comfortable, leave your arm supported rather than holding it up yourself.
4. Take Two Readings
Start the monitor and remain still and quiet. After the first measurement, wait at least one minute, then take another. Record both results.
Prepare two spaces in your notebook before starting. This makes it easier to record the pair without treating the second number as a replacement for the first.
Our blood pressure log guide provides a simple way to organise these sessions.
5. Agree on Timing With Your Clinician
Ask your healthcare professional which arm to use consistently, when to measure, and how many days to record.
If morning measurements are requested, clarify how they should fit around breakfast and medication. Do not delay or change prescribed treatment to create your own monitoring schedule. Mayo Clinic recommends learning the routine with your healthcare team and using the same arm for ongoing measurements.
Write the agreed schedule at the top of your log. Include a review date or instructions about when to send the results.
Useful questions include:
- Do you want morning and evening readings?
- Should I record on particular days or every day?
- How should I handle an error message?
- Which readings should prompt a call?
- When will we review the record?
6. Keep a Clear Record
A simple layout is enough:
| Date | Time | Reading 1 | Reading 2 | Notes |
|---|---|---|---|---|
| Example date | Morning | ___ / ___ | ___ / ___ | Questions or relevant context |
Label the columns clearly so another person can understand the record without an explanation.
If you use the monitor’s memory, check that you know how to display previous results. For a shared device, check how separate users are identified before relying on stored readings.
Take the record to your appointment. Bringing your monitor also gives your healthcare team an opportunity to assess the device and watch your technique.
What if the Reading Is Very High?
If the top number is above 180 or the bottom number above 120, and you have no concerning symptoms, wait at least one minute and repeat. If it remains that high, contact a healthcare professional immediately.
With chest pain, breathlessness, weakness, vision changes, or difficulty speaking, call your local emergency service immediately. Do not wait for a relaxation technique to change the reading.
Keep Monitoring Separate From Product Decisions
If you are exploring breathing exercises for blood pressure or reading about stress and high blood pressure, keep following your agreed measurement schedule.
Record when you start a new routine so you can discuss it at your review. Avoid deciding whether an approach works from a single pair of before-and-after numbers.

Your Home Measurement Checklist
Before your next session, have these items ready:
- Your monitor and its instructions.
- A suitable chair and arm support.
- Your agreed measurement schedule.
- A place to record both readings.
- Your clinician’s contact and escalation instructions.
Continue with the blood pressure log guide, or return to blood pressure readings explained to understand the numbers.
Home monitoring supports medical care. Do not change prescribed medication without your healthcare professional’s advice.
