Which device is used to assess a patient's blood pressure?

The sphygmomanometer is the device specifically designed to measure blood pressure. It typically consists of an inflatable cuff, a pressure gauge, and sometimes a stethoscope. When the cuff is inflated around the patient's arm, it temporarily restricts blood flow. As the cuff deflates, the gauge measures the pressure in the arteries, allowing healthcare professionals to determine both the systolic and diastolic blood pressure readings. This information is crucial in assessing a patient's cardiovascular health.

In contrast, a thermometer measures body temperature, while a stethoscope is used for listening to internal body sounds, such as heartbeats and breath sounds. An oximeter, on the other hand, is utilized to measure the oxygen saturation level in the blood. Each of these devices serves a distinct purpose in patient assessment, but none are appropriate for measuring blood pressure instead of the sphygmomanometer.
