Studies and Abstracts
Study objectives, methods and results, from airflow measurement to central apnea detection and titration protocols.
A three-part validation of the Wesper Lab AI scoring algorithm: AHI and CAI against simultaneous PSG in 45 participants, agreement among three scorers, and 139 clinical home sleep tests from...
Read studySimultaneous polysomnography and Wesper device testing in a sleep laboratory, with 45 patients in the final analysis: Pearson correlation of AHI was 0.951 and no adverse events were noted. Published...
Read studyTotal sleep time sets the denominator for AHI and hypoxic burden. This evaluation summarizes how an FDA-cleared automated scoring algorithm estimates it and how closely it matched manual PSG scoring.
Read studyIn a case series of 30 adults, frequent home sleep testing during hypoglossal nerve stimulation titration was associated with a mean titration time of 63 days and a 68% mean...
Read studyA study of 59 adults at four U.S. sleep clinics compared the Wesper Lab automated oxygen desaturation index with blinded manual scoring from simultaneous polysomnography.
Read studyA study of wireless chest and abdominal patches worn by 25 patients during polysomnography reports a strong correlation with PSG for apnea-hypopnea index, with no safety issues identified.
Read studyA study compared the Wesper automatic scoring algorithm with manual human scoring for central apnea index in home sleep apnea test recordings from multiple U.S. sleep clinics, including a blinded...

In a study of 11 providers, tuning the Wesper Lab automatic scoring algorithm to each provider's scoring patterns improved agreement with provider-scored...
ReadA patient diagnosed with mild sleep apnea after one night of testing averaged severe AHI across 17 nights of Wesper home testing,...
