Mandibular position and movements: Suitability for diagnosis of sleep apnoea

“…There are several unstandardized type 4 diagnostic devices consisting of one or two recording channels comprising oximetry, but their utility for diagnosing OSAS in different populations has yielded mixed results . Indeed, nocturnal oximetry as a stand‐alone signal is not currently recommended because the obstructive nature of identified events cannot be documented and not all events cause oxygen desaturation . Recently, the use of a single‐channel recording of nasal flow was proposed as a first‐line diagnostic for OSAS, despite the fact that not all recordings were interpretable .…”
