During an auscultatory blood pressure determination, the Korotkoff sounds that are listened for are produced because A. the partial pressure of the blood has been increased. B. the blood flow is turbulent. C. of the viscosity of the blood. D. the volume flow rate has decreased.
Option B. Turbulent blood go with the flow produces sound this is audible with a stetho- scope. Auscultatory systolic BP measurement calls for the artery to be squashed flat. At the factor simply earlier than blood flow is stopped the blood squirts thru the squashed artery in a turbulent fashion and this noisy squirting blood produces a sound audible with a stethoscope.
