How Is Blood Pressure Tested?

Having your blood pressure tested is quick and easy. Blood pressure is measured in millimeters of mercury (mmHg) and recorded as two numbers systolic pressure diastolic pressure.

Example: The doctor or nurse might say "140 over 80" as a blood pressure reading. Both numbers in a blood pressure reading are important. As we grow older, systolic blood pressure is especially important.

To test your blood pressure, your doctor will use a familiar device with a long name. It is called a sphygmomanometer, and may look something like this. The blood pressure testing devices use electronic instruments or digital readouts. In situation, the blood pressure reading appears on a small screen or is signaled in beeps, and no stethoscope is used.
