Monitoring blood pressure at home: who should do it and how

Not everyone needs to check their blood pressure daily, but for many, it is a life-saving habit. 

At Comprehensive Primary Care, our experts emphasize the importance of at-risk patients tracking these numbers outside of the doctor's office. Home monitoring allows you to see how your lifestyle and medications affect your heart health in real time.

Who should monitor their blood pressure?

We generally recommend home monitoring for patients diagnosed with hypertension or those with risk factors like obesity, diabetes, or a family history of heart disease. It is also helpful for patients who experience white coat hypertension, a condition where blood pressure rises only because of the stress of being in a medical office.

Nearly half of all adults in the United States have high blood pressure. Monitoring at home provides our team with a more comprehensive view of your health than a single reading during an annual exam. It helps us determine if your current treatment plan is working or if adjustments are necessary.

How to get an accurate reading

The accuracy of your data depends heavily on your technique. To get a proper reading, sit quietly for 5 minutes before starting. Make sure your back is supported, your feet are flat on the floor, and your arm is resting at heart level on a flat surface. You should not talk, use your phone, or drink caffeine for at least 30 minutes prior to the test.

We suggest taking two or three readings, spaced a minute apart, and averaging the results. It is also important to use a cuff that fits your arm correctly. A cuff that is too small or too large will provide inaccurate data. We recommend bringing your home monitor to our office so we can verify its calibration against our professional equipment.

Understanding your numbers

When you look at your monitor, you will see two numbers. The top number is systolic pressure, which measures the force in your arteries when your heart beats. The bottom number is diastolic pressure, which measures the force when your heart rests between beats.

A normal reading is typically below 120/80 mmHg. If your readings consistently stay above 130/80 mmHg, it is important to discuss these findings with us. Keeping a log of your results, including the date and time, helps our team make informed decisions about your care.

When to call our office

While home monitoring is a great tool, it does not replace professional medical advice. If you notice a sudden, significant spike in your blood pressure or experience symptoms such as chest pain, shortness of breath, or changes in vision, seek medical help immediately. These could be signs of a hypertensive crisis.
