What does the absence of Korotkoff sounds during blood pressure measurement indicate?

• A. A healthy artery
• B. A silent artery
• C. An increase in heart rate
• D. A decrease in blood volume

Answer: (B)

The absence of Korotkoff sounds during blood pressure measurement indicates a silent artery. Korotkoff sounds are the noises that medical professionals listen for when measuring blood pressure with a sphygmomanometer and stethoscope. These sounds are produced by the turbulent blood flow as the pressure in the cuff is decreased. If there are no Korotkoff sounds detected, it suggests that there may be an absence of blood flow or that the blood is flowing smoothly without turbulence. This condition can occur in several scenarios, such as in patients with certain vascular disorders or in cases of severe hypotension where there is insufficient pressure for blood flow to create the sounds. It is important to recognize this as it may indicate underlying issues that need to be investigated further.
