Multimodal Deep Learning to Predict Sleep Apnea Severity from SpO2 and Ballistocardiography
Official title: A Prospective Observational Study to Develop and Validate a Multimodal Deep Learning Model Integrating Peripheral Oxygen Saturation and Ballistocardiography Signals for the Prediction of Apnea-Hypopnea Index in Patients With Suspected Obstructive Sleep Apnea
Run by Fu Jen Catholic University · NCT07923825 · Data updated 2026-11-12
Researchers are testing a smart-mattress-based method that uses SpO2 and ballistocardiography data to predict sleep apnea severity in adults undergoing overnight sleep study.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 20 years or older referred for in-lab PSG due to suspected OSA who can provide informed consent.
✕Probably not a fit
Individuals without suspected OSA or with sleep disorders other than OSA may not benefit from this model for AHI estimation.

What this trial studies
This prospective observational study develops and validates a multimodal deep learning model that combines peripheral oxygen saturation and ballistocardiography signals collected from a smart mattress to estimate the apnea-hypopnea index. Adult participants referred for in-lab polysomnography with suspected obstructive sleep apnea will have synchronized SpO2 and BCG data recorded during sleep. The model’s predicted AHI will be compared with PSG-derived AHI using predefined metrics, with secondary analyses on OSA severity discrimination and signal feature associations. Data will be de-identified, and no changes to standard clinical care will be made. The study is led by Fu Jen Catholic University and conducted at its hospital site.
Why it matters
Potential benefit: If successful, this approach could enable non-invasive, convenient home-like screening or supplementary assessment to estimate OSA severity.
How similar studies have gone: Previous work has shown promise with single-modality signals; this study is exploring a multimodal approach, which is still relatively novel in this context.
