Quizplus · Accepted Answer

Phase IV of Korotkoff sounds is characterized by a soft tapping sound as the blood flows through the partially occluded artery. This sound corresponds to a decrease in blood pressure, specifically the diastolic pressure. Phase II is characterized by a swishing or whooshing sound and corresponds to the systolic pressure. Phase III is a sharp tapping sound, whereas Phase V is complete disappearance of sound, which corresponds to the diastolic pressure in children and can be used to estimate the mean arterial pressure in adults.
