The cessation of sounds during blood pressure measurement is known as the ________.

The cessation of sounds during blood pressure measurement is known as the second diastolic sound. This term refers to the phase in the process of measuring blood pressure using a sphygmomanometer and a stethoscope. When taking a blood pressure reading, the healthcare provider listens for sounds, known as Korotkoff sounds, which are produced by the turbulent flow of blood in the artery as pressure is released from the cuff.

The first sound you hear corresponds to the systolic blood pressure, which reflects the pressure in the arteries during heartbeats. As the cuff's pressure continues to decrease, the sounds change and eventually fade. The point at which these sounds are no longer audible indicates the diastolic pressure. It is this point that is referred to as the second diastolic sound, marking the return of laminar flow in the artery and representing the cessation of blood turbulence against the arterial wall. This measurement is crucial for diagnosing cardiovascular health, as it reflects the pressure in the arteries when the heart is at rest between beats.
