Which of the following is used to measure blood pressure?

Explanation:
Measuring blood pressure relies on a cuff-style device that can occlude and sense arterial pressure around the upper arm. This instrument is the sphygmomanometer. In manual practice, you inflate the cuff and then slowly release the pressure while listening with a stethoscope for Korotkoff sounds; the first sound marks systolic pressure and the point where sounds disappear marks diastolic pressure. Modern devices often automate this process using oscillometric detection, giving a BP reading without auscultation. The other items are not used to measure blood pressure: a crash cart is emergency equipment, a suction unit clears secretions, and a defibrillator delivers an electric shock to restore heart rhythm.
