Blood flow in the brachial artery compressed by a cuff

Abstract

Most non-invasive blood pressure measurements are based on the blood flow during the arm cuff deflation. In this paper, the measurement system for an investigation of a blood flow in the partially occluded brachial artery is presented. It allows us to record simultaneously the cuff pressure, Korotkoff sounds and the blood flow during the arm cuff deflation. The algorithms developed for digital processing of the recorded signals are described in detail. The results of analysis obtained for healthy subjects are presented and discussed.
