Continuous estimation of systolic blood pressure using the pulse arrival time and intermittent calibration
TL;DR: The results showed that the correlation coefficients between estimated values and invasively obtained systolic blood pressure reached 0.97±0.02, and the error remained within ±10% in 97.8% of the monitoring period.
Journal ArticleDOI
Real-Time Monitoring of Respiration Rhythm and Pulse Rate During Sleep
Xin Zhu,Wenxi Chen,Tetsu Nemoto,Y. Kanemitsu,Kei-ichiro Kitamura,Ken-ichi Yamakoshi,Daming Wei +6 more
TL;DR: This study suggests that the proposed method is promising to be used in a respiration rhythm and pulse rate monitor for real-time monitoring of sleep-related diseases during sleep.
Journal ArticleDOI
Development of a new method for the noninvasive measurement of deep body temperature without a heater.
TL;DR: The results show that the new dual-heat-flux method developed can be used for monitoring the deep body temperature as accurately as the conventional method, and it overcomes the disadvantage of the necessity of AC power supply.
Journal ArticleDOI
A Chair–Based Unobtrusive Cuffless Blood Pressure Monitoring System Based on Pulse Arrival Time
Zunyi Tang,Toshiyo Tamura,Masaki Sekine,Ming Huang,Wenxi Chen,Masaki Yoshida,Kaoru Sakatani,Hiroshi Kobayashi,Shigehiko Kanaya +8 more
TL;DR: The proposed system consists of an electrocardiograph, a photoplethysmograph, and a control circuit with a Bluetooth module, all of which are mounted on a common armchair to measure ECG and PPG signals from users while sitting on the armchair in order to calculate continuous PAT.
Journal ArticleDOI
