This is a video I made to demonstrate the Korotkoff sounds in relation to the reading on the sphygmomanometer. It was made to be used in a lecture here at the University of Sydney where the lecturer can talk the students through what is going on, hense there is no voice over, but the annotations should allow the video to stand alone.

The first part of the video is looking at the Shygmomanometer reading. At the end I have played the sounds again showing the audio recording, where you can see the various changes in the sound recorded which makes it a little bit easier to see some of the changes, eg the broad swishing sound for sound II, the loss of the swish again for sound III or the suddent drop in volume for sound IV etc

Feel free to use it if it is useful to you. Just let me know how you have used it in the comments so I can see in what ways others have found the video helpful. Thanks!
