Korotkoff sounds are generated when a blood pressure cuff changes the flow of blood through the artery. These sounds are heard through either a stethoscope or a doppler that is placed distal to the blood pressure cuff.
There are five distinct phases of Korotkoff sounds:
Phase 1: A sharp tapping.
This is the first sound heard as the cuff pressure is released. This sound provides the systolic pressure reading.
Phase 2: A swishing/whooshing sound.
Swishing sounds as the blood flows through blood vessels as the cuff is deflated.
Phase 3: A thump (softer than phase 1).
Intense thumping sounds that are softer than phase 1 as the blood flows through the artery but the cuff pressure is still inflated to occlude flow during diastole.
Phase 4: A softer, blowing, muffled sound that fades.
Softer and muffled sounds as the cuff pressure is released. The change from the thump of phase 3 to the muffled sound of phase 4 is known as the first diastolic reading.
Phase 5: Silence.
Silence that occurs when the cuff pressure is released enough to allow normal blood flow. This is known as the second diastolic reading.

what happens after, the pulse sound comes back?
I, myself personally can testify to the usefulness of this plan of action.Several other products I`ve tried only reduced the blood pressure momentarily. This is the first that does what it says. I simply need a short period of time, my blood pressure had gone right down to 145/90 and looked after it for a short time. Using Google to get this guide. It calls Jason Cυnobroke
Best luck

I guess that is easier than it sounds. Enough people do it.
I wish they wouldn't play that annoying music in the background when they are playing the last few sounds!
Thank you so much… you made the concept easier
Background music is disturbing…
So systolic is when you first hear pulse and dystolic is when you cant hear it any more????
Ever thought of demonstrating the sounds PER phase?! Smh…
Thank you
