What is the basis for the sounds referred to as Korotkoff sounds?

A. Laminar blood flow

B. Maximal blood flow

C. Turbulent blood flow

Correct answer is Turbulent blood flow.

Korotkoff sounds are sounds heard during measurement of Blood Pressure. This sound has different phases which can be identified by difference in sounds.
The basis of korotkoff sounds is turbulent blood flow. The turbulence here is created by applying pressure over the brachial artery using a BP cuff. Sound is heard only if there is vibration and vibration here is produced by turbulent flow. This sound is heard using a stethoscope which is kept over the cubital fossa in which the brachial artery lies.
Option A- Laminar flow doesn't cause any turbulence, so no sound is produced.
Option B- Maximal blood flow can cause turbulence (but not always) and produce a murmur is turbulence is present, but it won't produce the characteristic korotkoff sounds.
while measuring BP, the turbulent flow is created when the pressure in the BP cuff is in between the systolic pressure and diastolic pressure of that individual.
If the pressure in the BP cuff is higher than the systolic pressure, there will be no flow through the artery , so no sound is produced.
If the pressure in the BP cuff is lower than diastolic pressure, the flow will be streamline and it won't cause any turbulence and thus no sound is produced.
