What instrument is utilized to measure blood pressure?

The sphygmomanometer is the instrument specifically designed for measuring blood pressure. It typically consists of an inflatable cuff that is wrapped around the arm, along with a pressure gauge that provides readings. When measuring blood pressure, the cuff is inflated to temporarily restrict blood flow in the artery, and then it is slowly deflated while listening to the blood flow sounds using a stethoscope. This allows for the determination of systolic and diastolic pressure, which reflects the pressure in the arteries during heartbeats and between beats, respectively.

While the stethoscope is essential in conjunction with the sphygmomanometer to listen for blood flow sounds, it does not directly measure blood pressure itself. An electrocardiogram records the heart's electrical activity but does not assess blood pressure. The pulse oximeter measures oxygen saturation in the blood, which is unrelated to blood pressure measurement. Therefore, the sphygmomanometer stands out as the primary device for this vital health assessment.
