Systolic blood pressure is the maximum pressure exerted by the heart when it pumps blood through the arteries. It is one of the vital signs that is used to assess a patient's overall health.

The most common method for obtaining a patient's systolic blood pressure is through a manual blood pressure cuff. The cuff is placed around the patient's upper arm and inflated until it is snug. A stethoscope is then placed over the brachial artery in the patient's arm and the cuff is slowly deflated. The pressure at which the first sound is heard is the patient's systolic blood pressure.

Other methods for obtaining a patient's systolic blood pressure include automated blood pressure cuffs, which use an electronic sensor to measure the pressure, and oscillometric devices, which measure the pressure using a microphone.
