DreamKit Diagnostic Validation

The primary objective of this study is to assess the diagnostic performance of the DreamKit device against the gold-standard comparator, polysomnography (PSG). Data collection will be completed within a single visit, in which participants will undergo simultaneous measurement using the DreamKit device and in-laboratory PSG.
