Comparison of blood pressure measurements by Korotkoff
sounds and oscillometry. Oscillometric systolic blood pressure is recorded at the
point where cuff pressure oscillations begin to increase, mean pressure corresponds
to the point of maximal oscillations, and diastolic pressure is measured when the
oscillations become attenuated. Note the correspondence between these measurements
and the Korotkoff sounds that determine auscultatory systolic and diastolic pressure.
