WebKorotkoff sounds: ( kŏ-rot'kof ), characteristic noise heard over an artery when pressure over it is reduced below systolic arterial pressure, as when blood pressure is determined … WebAbstract. Korotkoff described the sequence of vascular sounds heard with a stethoscope over the brachial artery during deflation of a pneumatic cuff. The initial sounds are produced by vibrations of the vessel wall, although the sequence of vascular sounds has frequently been ascribed to 'turbulence' of flow in the vessel.
WebExpert Answer. 100% (1 rating) The Korotkoff sound is produced due to turbulence in blood flow caused by pressure in the cuff of sphygmomanometer. The sound heard during measurement of blood pressure is not the same sound as the heart sounds that are due to vibrations inside the v …. View the full answer. WebThe 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. Pressures beneath the midportion of the cuff showed a more ...
Web28 de ago. de 2024 · There are five Korotkoff sounds in all: 1. The first sound is heard when the cuff is inflated, and is caused by the sudden release of blood flow. 2. The second sound is a continuation of the first, and is caused by the blood flow becoming turbulent as it passes through the narrowing artery. 3. The sounds heard during the measurement of blood pressure are not the same as the heart sounds heard during chest auscultation that are due to vibrations inside the ventricles associated with the snapping shut of the valves. If a stethoscope is placed over the brachial artery in the antecubital fossa in a normal person (without arterial disease), no sound should be audible. As the heart beats, these pulses are transmitted smoothly via laminar (non-turbulent) blood flow throughout the arteri…
WebKorotkoff believed that an artery cannot produce any sound when it is completely compressed, as well as uncompressed. If the pressure in the cuff is relieved, blood starts coming through the compressed segment during systole, and Korotkoff considered this to be the cause of the first sound and a measurement of systolic blood pressure. When ...
