The sphygmomanometer is used to measure what?

A sphygmomanometer is a clinical instrument specifically designed to measure blood pressure. It typically consists of an inflatable cuff that is wrapped around the upper arm and a gauge that measures the pressure within the cuff. When the cuff is inflated, it temporarily occludes blood flow in the artery; as the cuff is slowly deflated, the healthcare provider listens with a stethoscope for the sounds of blood flow returning, which indicates the systolic and diastolic blood pressure.

This tool is fundamental in clinical settings as blood pressure is a critical indicator of cardiovascular health. Knowing how to use a sphygmomanometer and understanding blood pressure readings aids in the diagnosis and monitoring of various health conditions, such as hypertension, heart disease, and more. The options related to temperature, respiratory rate, and pulse involve different measurement tools and techniques, thus distinguishing the sphygmomanometer’s specific function in assessing blood pressure.
