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.

A quarter of Americans have high blood pressure, or hypertension. blood jetting through the vessel by the vibrations of the wall is called the Korotkoff sounds.

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. The artery collapses because cuff pressure exceeds diastolic pressure; it opens again with each beat because cuff pressure is less than systolic pressure. The sounds detected by the stethoscope in the auscultatory blood pressure measurement, known as Korotkoff sounds, are used to define systalic (high value) and diastolic (low value) pressures inside the arterial system. Blood Pressure and Korotkoff Sounds Audio 1) Inflate the cuff by pressing the 'Inflate Cuff' button several times 2) Deflate the cuff by selecting one of the 'Open Valve' settings 3) Close the valve 4) Read the blood pressure values while listening for Korotkoff Sounds 5) Switch between dial and This series of sounds is referred to as Korotkoff sounds (sometimes called K sounds), after the doctor who discovered them. To accurately measure blood pressure using the auscultatory (listening) 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. This is "Korotkoff Blood Pressure Sights and Sounds" by Medical Care Development on Vimeo, the home for high quality videos and the people who love them. Explanation: During the measurement of the blood pressure using a shygmomanometer, Korotkoff sounds are produced from under the distal half of the BP cuff.

Korotkoff sounds

Korotkoff sounds (or K-Sounds) are the "tapping" sounds heard with a stethoscope as the cuff is gradually deflated. Traditionally, these sounds have been classified into five different phases (K-1, K-2, K-3, K-4, K-5) and are shown in the figure below. Medical definition of Korotkoff sounds: arterial sounds heard through a stethoscope applied to the brachial artery distal to the cuff of a sphygmomanometer that change with varying cuff pressure and that are used to determine systolic and diastolic blood pressure. of Korotkoff sounds (e.g., atrial fibrillation) can decrease the accuracy of a mea - surement. Accuracy can be improved by decreasing the deflation rate and by taking an average of several Variation of the Korotkoff Stethoscope Sounds During Blood Pressure Measurement: Analysis Using a Convolutional Neural Network.

Korotkoff sounds will continue to be heard as the cuff pressure is further lowered. However, when the cuff pressure reaches diastolic pressure, the sounds disappear. Now at all points in time during the cardiac cycle, the blood pressure is greater than the cuff pressure , and the artery remains open.

They are named after The invention relates to a simulation method for Korotkoff sounds. According to the simulation method, a singlechip control unit and an audio decoding control The aim of this study was to compare features associated with the different phases of the Korotkoff sounds obtained during blood pressure measurement using a Korotkoff Sounds (5 phases); Phase 1: Clear sounds , highest level at which sounds are heard, it represents the systolic pressure. Phase 2: Sounds are replaced 30 Apr 2010 rural Montana What he is probably talking about are the “Korotkoff” sounds you hear when you are taking the blood pressure of your patient. When we say to you, “Okay, can you go and demonstrate a blood pressure, please?” it's actually the Korotkoff sounds that you're listening for.
