Keeping a blood pressure log at home can give you and your healthcare provider a clearer picture of your readings over time. Instead of relying on a single measurement taken during an office visit, a consistent record can show patterns that may be useful during your next appointment.
The American Heart Association recommends home monitoring for people with high blood pressure and notes that home readings do not replace regular medical visits.
In this guide, you’ll learn how to prepare for blood pressure readings at home, what information to record, and how to organize your results for your next primary care visit. You will also find a simple blank home blood pressure log you can print or copy into your preferred tracking method.
A blood pressure log is a tool for communication with your healthcare team. It should not be used as a reason to start, stop, or change medication on your own.
Why Keep a Blood Pressure Log
A single blood pressure reading is only a snapshot of your blood pressure at that moment. Recording readings over time can provide a more complete picture for you and your healthcare provider.
Your clinician may ask you to monitor your blood pressure at home when:
- You have been diagnosed with high blood pressure.
- Your treatment has recently started or changed
- Your healthcare provider wants additional information about your readings
- Your office and home readings appear different
A blood pressure tracking sheet can also help you remember when each reading was taken and what was happening around the time of the measurement.
What Do You Need Before Measuring
Choosing a Monitor and Cuff
The American Heart Association recommends an automatic, cuff-style monitor that measures blood pressure on the upper arm. Wrist and finger monitors are not recommended because they can provide less reliable readings.
Look for a validated monitor and choose the correct cuff size for your upper arm. If you are unsure which monitor or cuff is appropriate, ask your healthcare professional or pharmacist.
It can also be helpful to bring your home monitor to a medical appointment. Your healthcare professional can check that you are using it correctly and compare its readings with the equipment used in the office.
Preparing for a Reading
The way you prepare can affect your measurement. For more consistent blood pressure readings at home, the American Heart Association recommends:
- Avoid smoking, caffeine, and exercise for at least 30 minutes before measuring.
- Empty your bladder before the reading.
- Sit quietly for at least five minutes before measuring.
- Keep your feet supported and avoid talking during the measurement.
- Rest your arm on a flat surface so that the cuff is at heart level.
- Place the cuff on your bare upper arm rather than over clothing.
- Follow the instructions provided with your monitor.
Try to measure at the same time each day if your healthcare provider has asked you to monitor regularly. Your clinician can tell how often to take your readings based on your individual situation.
How to Record Your Readings
A simple blood pressure log does not need to be complicated. Each entry should include the date, time, blood pressure reading, and pulse if your monitor provides it.
Blood pressure is recorded as two numbers:
Systolic/Diastolic mm Hg
The systolic number is the top number, while the diastolic number is the bottom number.
AHA recommends taking two readings about one minute apart during each measurement session and recording both results.
Do not create your own medication schedule based on the readings. Instead, follow the measurement schedule recommended by your healthcare provider and bring your record to your appointment.
A Simple Blood Pressure Log to Use at Home
You can use the following original home blood pressure log as a simple tracking sheet. Print it, copy it into a notebook, or recreate it digitally.
What Should You Include in the Notes
The notes section can help you remember circumstances that may be useful to discuss with your healthcare provider.
Depending on your clinician’s instructions, you might note:
- Whether you had any symptoms
- When you took your usual medication
- Whether you had recently exercised
- Whether you had caffeine or smoked before measuring
- Whether you were feeling unwell or unusually stressed
- Any problems you had using the monitor
Context can be useful when reviewing a pattern, but it should not be used to automatically explain away a concerning reading. Your healthcare provider can help determine what your results mean.
What Should You Do About an Unexpected
If you get a reading that is higher than usual, do not immediately assume that one measurement represents your overall blood pressure. AHA advises taking another measurement and recoding both results. You should also contact your healthcare professional if you have concerns about the reading or your monitor.
If a reading is higher than 180/120 mm Hg, the AHA advises waiting at least one minute and measuring again. If it remains that high, contact your healthcare professional immediately.
Do not take an extra dose of blood pressure medicine, stop your medication, or change your treatment plan based on a home reading unless your healthcare professional has specifically instructed you to do so.
When to Call 911
A blood pressure reading above 180/120 mm Hg, along with certain symptoms, can indicate a medical emergency.
Call 911 if the reading remains above 180/120 mm Hg and you have symptoms such as:
- Chest pain
- Shortness of breath
- Back pain
- Numbness
- Weakness
- Changes in vision
- Difficulty speaking
The AHA advises not waiting to see whether the blood pressure decreases on its own when these emergency symptoms are present.

Frequently Asked Questions
What time of day should I record blood pressure?
If you are monitoring your blood pressure regularly, ask your healthcare provider which times and how often you should measure it. The American Heart Association recommends taking readings at the same time each day when following a home-monitoring schedule.
Should I write down both readings?
Yes. The American Heart Association recommends taking two readings about one minute apart and recording both results. Keeping both readings can give your healthcare provider more information when reviewing your log.
What if my home readings differ from the office readings?
Home and office readings can sometimes differ. Bring your log and home monitor to your appointment so your healthcare professional can review your technique and compare the equipment. The AHA specifically recommends bringing your monitor to an appointment to check that you are using it correctly and that the readings are comparable with office equipment.
Can I use an app instead of paper?
Yes. A digital app, your monitor’s memory function or another tracking method may be convenient if it allows you to keep an accurate record. The important part is having organized readings that you can review with your healthcare provider.
Should I change medication because of one reading?
No. Do not stop or change blood pressure medication based on home readings unless your healthcare professional tells you to do so. Home monitoring supports medical care but does not replace regular visits with your healthcare team.
