Using the "Transit Time Flow Measurement" Technique for Measuring Blood Flow in Vessels: Obtained Results

Abstract

This work is related to the measurement of volumetric blood flow in vessels[1], where the "Transit Time Flow Measurements" (TTFM) technique is used[2,3]. The intraoperative flow measurement in Bypass or Bridge - type coronary implants, is one of the most important operations during the surgery process. For it, an electronic module was designed whose operation principles have been registered some years ago, and nowadays, they continue being mentioned by manufacturers of very high cost commercial equipments, conceived for the same purpose. The module is described, the basic characteristics of the employed sensor are exposed and the preliminary results of the practical measurements are shown.
