What do you call the sequence of different sounds heard when measuring blood pressure?

The sequence of different sounds heard when measuring blood pressure is referred to as Korotkoff sounds. These sounds are produced by the turbulent blood flow through the arteries as the pressure in the cuff is released.

When the cuff is inflated, blood flow is temporarily occluded, and as the pressure decreases, the healthcare provider listens with a stethoscope placed over the artery. The first sound (the systolic pressure) marks the return of blood flow, while subsequent sounds (or their absence) reflect changes in blood flow until the sounds completely disappear (diastolic pressure).

Understanding Korotkoff sounds is essential for accurately determining both systolic and diastolic blood pressure values, which are critical indicators of cardiovascular health. This distinction highlights the importance of trained techniques in measuring blood pressure adequately and interpreting the sounds correctly.
