How does measurement work using a stethoscope?

A rubber cuff is inflated with a pump ball and the artery in the upper arm is compressed. While the air is released slowly from the cuff through a valve and the blood flows through the artery again, characteristic tapping sounds can be identified at the elbow with the stethoscope. These blood flow sounds are called Korotkow sounds after their discoverer, the Russian doctor Nikolai Korotkow. When the sounds first occur (systole) and when the sounds disappear again (diastole) is read from a manometer connected to the cuff tube.
