Abstract

Advancement in blood purification therapy extends not only to consoles and dialyzers, but also to patient management during blood purification therapy. However, no monitor has been devised for hemodynamics during blood purification therapy that is carried out continuously and non-invasively. By studying the laser Doppler flowmeter (LDF), we have developed a probe that can continuously measure changes in blood flow in tissues of the head and lower extremities during blood purification therapy. By applying the improved LDF, we have developed a non-invasive continuous monitoring method (NICOMM). Hemodynamics in various types of blood purification therapies were also studied by simultaneously measuring with an automatic oscillometric sphygmomanometer.
