This information explains how to monitor your blood pressure at home as part of your care at MSK. Your care team will give you information about how to set up and use the blood pressure machine they provide you.
The blood pressure measurements you take at home will help your care team make decisions about your care. They can help them diagnose high blood pressure. They also can use your home blood pressure measurements to adjust your blood pressure medications, if needed.
Before you start, you should already have set up your blood pressure monitor device. Follow the instructions you were given.
Before using your blood pressure monitoring device
Before taking your reading:
- Quietly rest in a seated position for at least 5 minutes.
- Make sure your blood pressure monitor is at the same level as your heart.
- Make sure your legs are uncrossed and your back is straight.
Use your blood pressure monitor device to take a blood pressure reading.
Review your results
See how your blood pressure reading matches the chart below (see Figure 1).

- You are the only person who should use your blood pressure monitoring device. Please do not share it with family members or friends.
