Development and Evaluation of Infrared Blood Pressure Monitoring System

Blood pressure monitors have been developed and sold widely and are in wide use throughout society, but these are primarily  what  are  termed  non-invasive  monitors.  The monitors  currently  available  have  some disadvantages including discomfort for the patient caused by painful cuff inflation,  which  may  actually  influence  blood  pressure readings,  and  the  unfeasibility  of  continuous  or semi-continuous  blood  pressure  monitoring  due  to  the necessity for repetitive cuff inflation and deflation. Cuffless blood  pressure  measuring  systems  have  been  developed which  help  to  solve  these  problems,  and  in  this  paper, infrared cuffless blood pressure monitoring system and its effectiveness  and  practicality  are  introduced.  Their measurement principles  are  described  and  their performance  evaluation  is  also  explained.  The  primary disadvantage  of  steering-type  blood  pressure  monitoring monitoring systems currently suffer from some time lag in reporting of results.
