What is a sphygmomanometer used for?

  1. Measuring blood pressure

  2. Checking body temperature

  3. Monitoring heart rate

  4. Counting respiratory rate

The correct answer is: Measuring blood pressure

A sphygmomanometer is specifically designed to measure blood pressure, making it an essential tool in healthcare settings. This device typically consists of a cuff that wraps around the arm and a gauge that measures the pressure of blood in the arteries as the cuff is inflated and then released. Blood pressure readings are critical for assessing cardiovascular health, diagnosing conditions such as hypertension, and monitoring treatment effectiveness. The other options refer to different medical instruments: gauging body temperature is done with a thermometer, monitoring heart rate typically involves a pulse oximeter or heart rate monitor, and counting respiratory rate may be achieved through visual observation or specialized respiratory monitors. Each of these processes uses distinct tools tailored for their specific measurements, underscoring the unique function of the sphygmomanometer in evaluating blood pressure.
