释义 | Korotkoff soundsKo·rot·koff sounds(kŏ-rot'kof),Ko·rot·koff sounds(kō-rot'kof sowndz)Korotkoff soundsThe 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. The sounds get louder as the cuff pressure continues to fall, but then there is a sudden muffling. This is Korotkoff phase IV; the cuff pressure at this point has, in the past, been taken as the diastolic pressure. Soon after that the sounds disappear altogether. This is Korotkoff phase V, the cuff pressure at which is now generally taken as the diastolic.
