Development of the cuffless blood pressure estimation system for continuous health monitoring

Abstract

In healthy longevity society, prevention of lifestyle-related diseases and enhancement of home healthcare are required for improvement of QOL (quality of life). It is well known that blood pressure estimation is useful for prevention of hypertension and patient monitoring. It is the key technology for improvement of QOL, but the measurement by using a cuff all the time is a heavy burden. Therefore, we co-developed “the continuous health monitoring system with the cuffless sphygmomanometer using the pulse wave” to facilitate health care and home care patient monitoring. In particular, we constructed a cloud system to collect and manage blood pressure data using the internet and a wristwatch type photoplethysmograph sensor. Thus we applied the cuffless blood pressure estimation by a single photoplethysmograph sensor to the continuous health monitoring system.
