What does a sphygmomanometer measure?

A sphygmomanometer is a medical device specifically designed to measure blood pressure, which is the force of blood against the walls of the arteries. This instrument typically consists of an inflatable cuff that is wrapped around the upper arm and is connected to a pressure gauge. As the cuff inflates, it restricts blood flow, and the clinician can determine the systolic and diastolic blood pressure by observing the gauge as the cuff deflates.

This measurement is crucial in assessing cardiovascular health and diagnosing conditions like hypertension, which is critical in the context of healthcare dynamics, as elevated blood pressure can lead to more severe health issues such as heart disease and stroke. Understanding blood pressure readings is vital for both patient assessment and monitoring the effectiveness of medical treatments.
