Know your numbers: blood pressure at home
High blood pressure usually has no warning signs, so feeling fine doesn't tell you much. In half an hour you'll know how to take a proper reading, have your first two numbers written down, and have a log to hand your doctor.

Read this first
- Call 911 right away for chest pain or discomfort, shortness of breath, or sudden numbness or weakness on one side, trouble speaking or seeing, or a severe headache with no known cause.
- Readings above 180/120 are dangerously high. NHLBI says they need immediate medical attention. Contact your provider right away.
- Your cuff doesn't diagnose you. NHLBI says a diagnosis takes two or more readings at separate medical appointments. Bring the log, and ask before changing any medicine.
- Feeling fine isn't a number. High blood pressure usually has no warning signs. Measuring is the only way to know.
Steps
- Get a cuff that fits. Use an approved home monitor with the right cuff size, or a pharmacy blood pressure machine.
- Set up 30 minutes ahead. No food, caffeine, alcohol, smoking or exercise for 30 minutes. Empty your bladder first.
- Sit right and rest five minutes. Back supported, feet flat, legs uncrossed, arm on a table at chest height, cuff on bare skin. Rest 5 minutes.
- Take two readings. Stay quiet and take two readings, one or two minutes apart.
- Write both down. Write the date, time and both readings in your log, every time.
- Repeat at the same time daily. Measure at the same time each day, as often as your health care team says.
- Take the log to your doctor. Bring the log to your doctor and ask what the numbers mean and how often to check.
If it stalls
- If the first reading looks high, don't panic and don't skip the second one. Rest, take it, and write both down.
- If you keep forgetting, set a daily phone alarm and leave the cuff and log on the table where you'll see them.
