Abstract

The accuracy of the auscultatory method of blood pressure measurement has been significantly improved in recent years by the adoption of standards involving cuff size and application techniques. Nevertheless, individual errors may still be as high as 20 mmHg. In previous theoretical work, a mathematical model was developed to analyze the origin of the Korotkoff sound. This model predicted that the sound would be affected by the state of the vascular bed distal to the cuff. Experiments were conducted in which vascular properties in the arm distal to the cuff were altered by noninvasive stimuli, Comparison of Korotkoff sound amplitude and energy between control and experimental conditions confirms the model's prediction.
