Daily use to CPAP treatment appears as a key factor to improve patients' health status. In France, since October 2013, patients newly treated by CPAP have to be equipped with a telemonitoring device remotely evaluates patient's treatment duration on a daily basis. That's why SADIR developed the TeleObs®. The aim of this study was to evaluate TéléObs® in a bench test: its possible impact to the CPAP treatment and its accuracy in measuring treatment duration and Apnea Hypopnea Index (AHI). Methods: All tests were made using the active test lung ASL 5000 (IngMar Medical, USA). Seven currently used CPAP treatment devices were tested with sessions' duration between 3 to 8 hours and AHI varying between 0.33 and 30 events per hour. Measured values sent from a communicating module were read from a certified telemedicine server, H2AD, located in France via a web interface. Preliminary results: The impact of the TéléObs® sensor on the CPAP treatment was found to be negligible. The maximal observed pressure drop was 0.18 cmH2O. The difference between the treatment duration measured by the device and actual values was 17 seconds in average [-0.5 sec; +8.8 min]. The difference between actual AHI and TéléObs® measured values was 0.55 in average [0; 3.8]. Conclusion: TéléObs® proved to be an accurate tool for monitoring CPAP use. It correctly measures critical parameters to evaluate the patients' adherence and effectiveness of the treatment. Plus, no major impact of installing TeleObs® in the respiratory circuit was noticed in any of the CPAP models tested.
