What techniques are commonly used to measure blood pressure?

The correct choice involves sphygmomanometry or electronic blood pressure monitors, which are specifically designed for measuring blood pressure. Sphygmomanometry involves the use of a cuff inflated around the arm to restrict blood flow, and a pressure gauge to determine the pressure at which blood flow begins again when the cuff is deflated. This method provides critical readings of systolic and diastolic pressure, essential for diagnosing and managing cardiovascular health.

Electronic blood pressure monitors use similar principles but automate the measurement process, providing results on a digital display. These devices are user-friendly and widely adopted in both clinical settings and home use for regular monitoring.

The other techniques are not utilized for blood pressure measurement. A stethoscope and thermometer serve different purposes, primarily for listening to heartbeats and measuring body temperature, respectively. Pulse oximetry is a technique used to measure oxygen saturation levels in the blood, while urinalysis assesses the composition of urine for various health indicators. Each of these methods plays a significant role in patient assessment but does not contribute to blood pressure measurement.
