Prior to Test

Unless instructed otherwise, you should sit quietly for a few minutes. This ensures a more accurate reading of your resting blood pressure.

Description of Test

A soft cuff will be wrapped around your upper arm and inflated with air. The cuff will press on the large artery in your arm. When inflated, it will briefly stop the flow of blood. The air in the cuff will then be slowly released. The person taking your blood pressure will use a stethoscope to listen for the sound of blood as it begins to flow again. Sometimes the cuff will be put on your leg instead of your arm.

Two numbers will be recorded from the attached gauge. The first sound that is heard is the systolic pressure. This is the pressure when the heart is squeezing and pushing the blood forward. It will be recorded as the top number. The last sound to be heard is the diastolic pressure. This is the pressure when the heart is relaxing. It will be recorded as the bottom number of the reading. .

Some blood pressure machines automatically inflate and deflate. The machine will record your blood pressure and provide you with a reading.

After Test

If the reading is part of a routine exam, you can resume your normal activities after the test.

How Long Will It Take?

Less than a minute

Will It Hurt?

There may be some momentary squeezing pressure as the cuff inflates around your arm. A blood pressure measurement should not be painful.

Results

If you have an abnormal blood pressure, your doctor may suggest further testing or a treatment plan.

Blood pressure readings vary depending on a number of factors, including recent exercise.

Blood pressure is measured in millimeters of mercury (mm Hg). A range of values defines normal blood pressure. For a healthy adult with no medical problems, these are the ranges your doctor is looking for:

• A blood pressure reading of less than 90 over 60 may be a sign of hypotension.
• A blood pressure less than 120 over 80 is considered normal.
• A blood pressure between 120-139 over 80-89 is classified as prehypertension, meaning that your blood pressure is elevated.
• Having many accurate blood pressure readings that are all 140 over 90 or higher is a sign of hypertension.

If you have a disease such as diabetes or kidney disease, the ranges may be different. Talk to your doctor about where your blood pressure range should be.
