Abstract

Background: Modern CPAP and sleep tele-monitoring (STM) devices are capable of estimate OSAS treatment efficiency by measuring residual AHI on therapy. Their AHI measurement accuracy is often evaluated and compared either by bench-testing with lung simulator, or in-situ testing with real-life patients.

Objectives: A new approach in comparative study of AHI measurement accuracy for both CPAP and STM devices. It aims to associate the repeatability and representatively of two above approaches.

Methods: We collect flow data from OSAS patients undergoing PSG exam in sleep laboratory, then use lung simulator to reproduce them during bench-testing. A set of 17 flow patterns were acquired, from patients at different severities. Two representative CPAP and a STM devices (T4P) were compared. Their AHI results were compared to PSG reference result.

Result: Both the CPAP and STM devices are capable of qualitatively distinguish a healthy or well treated patient (AHI<10) from a not well treated one (AHI>10). Their AHI estimations are in overall under-estimated with respect to the reference one, owing to the lack of others physiologic signals. Finally, the STM device gives less extreme AHI estimation than the CPAP devices.

AHI comparison: values are calculated versus PSG reference

Conclusion: The proposed approach was used to reproduce a set of real-life patient respiration for each CPAP and STM device, thus put them on a fair comparative ground. Our approach can be used for improving device AHI diagnostic efficiency or for a comparative study.
