What are Korotkoff sounds?

Korotkoff sounds are the specific sounds that medical personnel listen for when measuring blood pressure using a sphygmomanometer. These sounds are produced by the turbulent blood flow through the arteries as the pressure in the cuff is gradually released. As the cuff deflates, the clinician can hear distinct sounds that indicate the systolic and diastolic pressures, which are critical for diagnosing and monitoring cardiovascular health.

Understanding the significance of these sounds is essential for accurate blood pressure assessment. The first Korotkoff sound corresponds to the systolic pressure, while the point at which the sounds disappear indicates the diastolic pressure. This method of measuring blood pressure is widely used and is fundamental in clinical practices.
