Question

When the cuff pressure is high enough to keep the brachial artery closed, no blood flows through it and no sound is heard. When cuff pressure decreases and is no longer able to keep the artery closed, blood is pushed through, producing turbulent blood flow and a sound. Systolic pressure is the pressure at which the first korotkoff sound is heard. At first, the artery is closed during systole but as cuff pressure continues to decrease, the artery partially opens. Turbulent blood flow during systole produces pulse sounds, although the pitch of the sounds changes as the artery becomes more open.

Answer 1

Answer:

Korotkov sounds are the sounds that medical personnel listen for when they are taking blood pressure using a non-invasive procedure. They are named after Dr. Nikolai Korotkov, a Russian physician who discovered them in 1905,[1] when he was working at the Imperial Medical Academy in St. Petersburg, the Russian Empire.[2]
