A Cuffless Blood Pressure Monitor for Home Healthcare Systems Monitored by Health Professionals - A cuffless blood pressure monitor

摘要

We tested a new model of healthcare that involves monitoring physiological parameters to improve team-based healthcare. The system consisted of unobtrusive monitoring, a database, and interventions by health professionals. This report discusses the core technologies used, focusing on those involved in monitoring. An unobtrusive blood pressure (BP) estimation system, and web-based care system, including its database, were designed and tested. BP was estimated with a cuffless BP monitor combined with electrocardiography and photoplethysmography. The mean difference (MD) of estimated SBP and reference SBP was 0.2 ± 5.8 mmHg and the limits of agreement ranged from -11.2 mmHg to 11.6 mmHg. The MD of estimated DBP and reference DBP was 0.4 ± 5.7 mmHg and the limits of agreement ranged from -10.8 mmHg to 11.6 mmHg. The estimated BP was enough accurate compared with the cuff-based BP. The core technologies operated well. The proposed system may prove effective for home-based healthcare. Further studies are needed to evaluate the entire care system.
