Abstract Multi-night measurement of obstructive sleep apnea (OSA) using AI-enabled technologies could reduce misdiagnosis rates from night-to-night variation. However, prospective feasibility and effectiveness of multi-night assessment in clinical populations remains uninvestigated. In this study, 100 people with suspected OSA were recruited to receive an under-the-mattress Withings Sleep Analyzer (WSA) to quantify in-home sleep for 3 months alongside single-night polysomnography.

1 INTRODUCTION Sleep is critical for optimal daytime function, performance, safety and health. Thus, accurate and reliable estimates of sleep are important to help manage these key outcomes. However, sleep is difficult to objectively evaluate, particularly over extended multi-day periods. This is partly because gold-standard quantification of sleep, polysomnography, is expensive and complex to administer over multiple nights.

1 INTRODUCTION The ‘gold standard’ objective method of measuring sleep is polysomnography (PSG). This method uses electroencephalography (EEG) to record brain electrical activity, from which wake, rapid eye movement (REM) and non-REM sleep are typically scored manually in 30-s epochs.
