See your night

See what was happening while you were asleep.

SomnoTrak turns overnight measurements into a visual picture of your sleep and oxygenation. You can see oxygen drops, low-oxygen exposure, breathing-related events, heart rate and when important changes occurred during the night.

SomnoTrak nightly oxygenation and sleep report
Your overnight physiology becomes visible.

Instead of wondering what happened during the hours you cannot remember, you can actually review the night.

The value of time

One night shows you a moment. Your history shows you the pattern.

Each night adds another piece of information. Over days and weeks, SomnoTrak can reveal whether oxygenation, sleep quality and overnight events are changing or remaining consistent.

See whether a treatment or lifestyle change corresponds with measurable improvement.
Recognize recurring nights and patterns that may otherwise be easy to overlook.
Compare recent results with your own history instead of treating every night in isolation.

Detects recurring oxygen-desaturation patterns
Reveals when events cluster during the night and across sleep stages
Highlights consistency, variability and changes that warrant a closer look
