Blood pressure is usually measured in a doctor’s office with device known as a sphygmomanometer. A sphygmomanometer has an arm cuff, dial, pump, and valve. Your doctor will use a stethoscope also. The stethoscope is used to listen to the Korotkoff sounds. The appearance of the sound indicates the systolic blood pressure and the disappearance of Korotkoff sound defines the diastolic blood pressure.
Blood pressure in children and teens is measured in the same way as in adults using a sphygmomanometer. But the cuff used for children is smaller than the cuff used in adults.
At times an electronic instrument may be used to measure your blood pressure. If your BP is high when measured by electronic BP instrument, your doctor will measure your BP manually with a sphygmomanometer. The sphygmomanometer is most accurate for measurement of BP.
