Korotkoff sounds are the sounds that medical personnel listen for when they are taking blood pressure using a non-invasive procedure. They are named after Nikolai Korotkov , a Russian physician who discovered them in 1905, [ 1 ] when he was working at the Imperial Medical Academy in St. Petersburg , the Russian Empire.
An auscultatory gap, also known as the silent gap, [1] is a period of diminished or absent Korotkoff sounds during the manual measurement of blood pressure.It is associated with peripheral blood flow caused by changes in the pulse wave. [2]
Korotkoff sounds are pulse-synchronous circulatory sounds heard through the stethoscope in auscultation of blood pressure using Riva-Rocci's sphygmomanometer. Korotkoff test or Korotkoff sign is a collateral circulation test: in aneurysm, if the blood pressure in the peripheral circulation remains fairly high while the artery above the aneurysm ...
When blood just starts to flow in the artery, the turbulent flow creates a "whooshing" or pounding (first Korotkoff sound). [14] The pressure at which this sound is first heard is the systolic blood pressure. The cuff pressure is further released until no sound can be heard (fifth Korotkoff sound), at the diastolic arterial pressure.

In 1905, Nikolai Korotkoff improved the technique by describing the Korotkoff sounds that are heard when the artery is ausculted with a stethoscope while the sphygmomanometer cuff is deflated. [2] Tracking serial blood pressure measurements was further enhanced when Donald Nunn invented an accurate fully automated oscillometric sphygmomanometer ...

Pulse pressure is quantified using a blood pressure cuff and stethoscope (Korotkoff sounds), by measuring the variation of the systolic pressure during expiration and inspiration. [8] To measure the pulsus paradoxus, place a blood pressure cuff on the patient's arm and very slowly deflate the cuff while listening for brachial pulsations.
