The Daily view stacks one night's channels on a shared time axis. Read it top to bottom
and the night tells a story.
Flow rate — the breath-by-breath trace. This is the channel every event is scored
from, and the one worth zooming into. Flattened tops, a sawtooth, or a run of shallow
breaths followed by a big recovery breath all look distinct once you have seen them.
Pressure — what the machine delivered. On an auto machine, watch where it rises: a
pressure that climbs and then holds is responding to something.
Leak — the channel that invalidates everything else when it goes wrong. A high leak
stretch means the machine's event scoring over that stretch is unreliable, so read leak
first and events second.
Event markers — apneas, hypopneas, and the machine's own extra event types. Their
clustering is usually more informative than their count.
Snore / flow limitation, where your machine records them.
Oximetry (SpO2 and pulse), when a compatible oximeter recorded that night.
Three habits worth having:
Zoom in. A whole night squeezed into one screen hides everything interesting.
Ten-minute windows around a cluster are where the answers are.
Check the axis before you react. Charts auto-scale; a dramatic-looking excursion
may be two units wide.
Nights run noon to noon. A session starting at 1 a.m. on the 15th belongs to the
14th's night. This is deliberate and it is why "my night is missing" almost always
resolves to "it is on the previous date".
Post a night in Data Talk if you want a second pair of eyes — there is a topic there
on how to share a screenshot safely first.
Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.
