Blood Pressure Screening

Overview

A blood pressure monitor is used to screen for high blood pressure. A blood pressure cuff, Opens dialog is wrapped around your upper arm. The cuff is then pumped up. The cuff is slowly deflated, and the monitor shows your blood pressure numbers. Either an automatic or manual monitor can be used.

After measuring your blood pressure, your doctor may ask you to test it again when you are home. This is because your blood pressure can change throughout the day. And sometimes blood pressure is high only because you are seeing the doctor. This is called white-coat hypertension.

Your doctor may ask you to monitor your blood pressure at home. You may get an ambulatory blood pressure monitor or a home blood pressure monitor.

Who should be screened for high blood pressure and how often?

The U.S. Preventive Services Task Force (USPSTF), Opens dialog recommends screening adults age 18 and older for high blood pressure. You can get your blood pressure checked during any routine medical visit.

  • You're at a higher weight or you have obesity.
  • Your doctor has recommended checking it based on your blood pressure numbers.
