How is hypertension diagnosed and measured?

Hypertension is diagnosed and measured through blood pressure readings.

Blood pressure is typically measured using a sphygmomanometer, a device that consists of an inflatable cuff and a pressure gauge. The cuff is wrapped around the upper arm, and air is pumped into it to temporarily cut off blood flow. As the air is slowly released, the healthcare professional listens for the sound of blood flow using a stethoscope (auscultatory method) or relies on digital readings (oscillometric method). The two blood pressure values recorded are systolic pressure (the higher number) and diastolic pressure (the lower number), measured in millimeters of mercury (mmHg).
