WebThe Korotkoff sounds appear after you inflate the cuff (which compresses the artery/blood flow) and then begin to deflate the cuff. The Korotkoff sounds are the result of the turbulent blood caused by the inflated cuff compressing the artery and oscillations of the arterial wall when the heart beats during cuff deflation. Here are a few tips: There are five Korotkoff sounds: Phase I: The first appearance of faint, repetitive, clear tapping sounds which gradually increase in intensity for at least two consecutive beats is the systolic blood pressure.Phase II: A brief period may follow during which the sounds soften and acquire a … Meer weergeven Korotkoff sounds are the sounds that medical personnel listen for when they are taking blood pressure using a non-invasive procedure.
