Three different engines with three different jobs. They are often confused, so: SomniScan — the deep pass over a night's waveform Where the Daily view draws what the machine recorded, SomniScan goes back over the high-resolution flow data itself and looks for what the machine's own scoring did not flag. Its output is a set of findings about a specific night with the evidence attached. SomniPattern — the pass across many nights A single night is noise; twenty nights is a signal. SomniPattern looks for repetition: events clustering at the same hour, a channel drifting week over week, nights that group into recognisable types. It answers "is this a pattern or was that one bad Tuesday?". Somni-UARS — the specific hunt for upper-airway resistance Flow limitation and airway resistance do not always produce scoreable apneas or hypopneas, which is exactly why they get missed. This engine looks at breath morphology for that signature rather than at the event count. What they all have in common They read the same imported data you can see. Nothing is inferred from outside your account. They produce observations, not diagnoses. A finding is a place to look, and a good thing to raise with your clinician — it is not a verdict, and it does not replace a sleep study. They are part of the advanced tier. Locked tiles say which one they need. Bring findings here if you want help reading them. Bring them to your clinician if you want to act on them. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.
