Korotkoff sounds, named after Dr. Nikolai Korotkoff, a physician who described them in 1905, are sounds that physicians listen for when they are taking blood pressure. When the cuff of a sphygmomanometer is placed around the upper arm and inflated to a pressure above the systolic pressure, there will be no sound audible because the pressure in the cuff would be high enough to completely occlude the blood flow.

This is a video I made to demonstrate the Korotkoff sounds in relation to the reading on the sphygmomanometer. It was made to be used in a lecture here at the University of Sydney where the lecturer can talk the students through what is going on, hense there is no voice over, but the annotations should allow the video to stand alone. The first part of the video is looking at the

Interpretation. Korotkoff sounds. Definition: Do NOT use upward deflections on the manometer to measure systolic pressure. Continue deflating, record the disappearance of Korotkoff sounds as the diastolic Korotkoff sounds: development of the sphygmomanometry research at the This article pays homage to Sergei Nicolai Korotkoff, for the cente-nary of the Listening to Korotkoff sounds (K-sounds) to determine systolic and diastolic blood pressure (BP) has been the standard for noninvasive BP measurement in The pressure within the compression cuff indicated by the level of the mercury column (or the aneroid pointer), at the moment the Korotkoff sounds are first heard 31 Mar 2014 Since Korotkoff sounds are low frequency sounds , it is best heard with bell of the stethoscope ? How many of us do it ? There is little surprise , This is the systolic pressure. Continue to deflate the cuff until the sounds disappear.

These sounds are heard through either a stethoscope or a doppler that is placed distal to the blood pressure cuff. Korotkoff sounds are produced underneath the distal half of the blood pressure cuff. 17 The sounds appear when cuff pressures are between systolic and diastolic blood pressure, because the underlying artery is collapsing completely and then reopening with each heartbeat.

PMID: 10226281 Abstract We were interested in the Korotkoff sounds (as much as 10 mmHg2, 7) is clinically significant, because this difference approaches the difference between nominal normal diastolic pressure (80 mmHg) and the threshold for diagnosis and treatment (90 mmHg). Hence the choice of diastolic endpoint can be Korotkoff sounds The sounds heard through a stethoscope held over a compressed artery with each pulse beat as the compression is gradually released, in the process of measuring the blood pressure with a SPHYGMOMANOMETER.The first pulse sound heard as blood is able to pass through the narrowed artery is Korotkoff phase I. 2021-02-05 What are Korotkoff Sounds?

They are are used to measure the systolic and diastolic BP. The Korotkoff sounds coincided with a small dip and ensuing steep rise in pressure immediately beyond the distal edge of the cuff. Sound intensity paralleled not only the rate and the acceleration of this steep ascent, but also the total pressure through which it was maintained. Korotkoff sounds source: www.researchgate.net Are the sounds we hear during Stethoscope during the measurement of arterial pressure, consisting of five stages, namely : For patients with sounds not audible per auscultation (eg, those with weak Korotkoff sounds), a Doppler probe can be used over the brachial artery to determine the patient's systolic pressure.

These sounds are heard between systole and diastole. They are are used to measure the systolic and diastolic BP. This sound is called Korotkoff sound. The beginning of the Korotkoff sound indicates systolic BP (see the third arm of previous diagram). As the deflation continues, Korotkoff sound disappears, at certain point (see the fourth arm of the previous diagram).
