What are the sounds heard over a blood vessel when the vessel is partially compressed?

Sounds of Korotkoff


What is the medical term for when sounds stop and restart while taking BP?

The first Korotkoff sound is when you first hear the pulse, and the fifth Korotkoff sound is when you no longer hear the post. Sometimes, there will also be an "auscultory gap," when you have a period with no sounds with korotkoff sounds heard before and after the gap.

Are the sounds of Korotkoff like a pulse?

Yes and no. They certainly sound like a pulse! But the pulse is a feeling of blood flow through a vein, whereas Korotkoff sounds are the sounds of turbulent blood flow through a constricted or partially occluded artery.


Sounds of turbulent blood flow that occur when blood flow resumes in an artery that has been occluded is what?

How do you Explain the underlying cause of the Korotkoff Sounds that you detected with the Cardio Microphone as the cuff pressure was decreased?

When the blood pressure cuff is inflated, the blood flow is stopped. Slowly the cuff is decreased. When the technician starts to hear the blood flow, these are called Korotkoff Sounds. This pressure point defines the systolic pressure.


What does the korotkoff sound mean to us?

CHECK YOUR BLOOD PRESSURE Korotkoff sounds are certain specific sounds heard when the arteries decompress and move the blood along them. They were invented by a Russian professor - Nikolai Korotkoff in the early 20th century during the 1st world war and remain the best ausculatory way to measure arterial blood pressure. When an artery is totally compressed, no sounds can be heard at all as no blood is moving. As the artery is slowly decompressed, certain sounds are heard which indicate a way of judging the level of pressure in the artery. In order to slowly decompress the artery we need to use an inflatable sphygmomanometer cuff and a stethoscope. The cuff is pumped up until no sound can be heard. Then the cuff is slowly deflated and the sounds occur: They occur in four stages : silence-tapping-thumping-muffled-silence again when the cuff is fully deflated and the artery is completely unobstructed. When the first sound is heard - the tapping, the reading on the sphygmomanometer is taken to be systolic pressure. The moment all the sounds disappear and you are left with silence again, the reading on the sphygmomanometer is taken as diastolic pressure. This is the way by which your blood pressure will always be taken at your local GP or health clinic. The standard BP is 120/80 which is systolic/diastolic. However it is likely that people will have blood pressure values of near that value and still be perfectly healthy.


What sound get between systolic and diastolic blood pressure?

If you are manually taking a blood pressure measurement using a sphygmomanometer and stethoscope, the sounds you hear between the systolic and diastolic blood pressure are called Korotkoff sounds, and they are muffled "whooshing" sounds heard with each heart beat and are thought to be caused by turbulent blood flow through the blood vessel caused by partial occlusion by the cuffed sphygmomanometer.
