A Feasibility Study of Wearable Device in Assessing Respiratory Condition Change of Patients With Exacerbation of COPD

"SG is a wireless, wearable medical device, which includes nano-based sensors. It can seamlessly measure patient's tidal breathing during daily activities. SG extracts series of critical respiratory parameters, including; Respiration Rate (RR), Inhalation and Exhalation duration and ratio (I/E), as well as novel biomarkers. SG parameters are applicable to evaluate COPD patients' condition, or for monitoring patients with other respiratory conditions.~SG components are:~RSM (Respiratory Sensing Module): non-invasive module with sensors that can detect the exhaled humidity and condensation. The RSM is a non-sterile, disposable, single patient use.~ECU (Electronic Control Unit): a re-usable, wireless data acquisition and transmission unit. The ECU is connected to the RSM during the measurement and transmits the data via Bluetooth to the SG software.~SenseGuard™ Software: for data management, acquisition, processing, logging and presentation of the digital respiratory signals."
