Remote Patient Monitoring System Based on Wireless Wearable Chest Patch

Remote patient monitoring (RPM) enables healthcare professionals to virtually care for patients. This paper presents a novel RPM system, 'Leo' that includes a wearable chest patch, adhesives, charging cable, mobile application and a cloud-based analytics platform. It records ECG, impedance, accelerometer and gyroscope signals and outputs heart rate (HR), respiration rate (RR) and body position. To test the performance of Leo, 35 children were recruited. The study consisted of 2 clinic visits on consecutive days. During which the Leo system was compared with gold-standard devices for HR and RR while participants performed different breathing maneuvers in different positions. Between visits, participants wore the Leo device for up to 24 hours at-home while continuing their daily activities. During clinic visits, HR measured by Leo was highly correlated with gold-standard (r = 0.99). RR measured by Leo was also very high correlated with gold-standard (r = 0.97). For 24 hour at-home monitoring, the Leo was able to collect on average 17.4 hours of data per participant. These results highlight the potential clinical use of Leo as an RPM system.
