  • Low oxygen threshold you choose, for example 90%

Your morning summary

Two numbers that sum up the night

Your O2 Score puts the whole night on a scale of ten. Your ODI counts how many times an hour your oxygen dropped, at both the 3% and the 4% level. Below them, the time you spent in each oxygen range, and space for your own notes.

  • O2 Score out of 10
  • ODI at 3% and 4%, with drop counts
  • Oxygen and pulse distribution through the night

Professional reports

The file you hand to your doctor

  • Time spent in each oxygen band
  • ODI 3% and 4%: number of drops, time in drops, average length
  • Your own thresholds, and the full oxygen, pulse and movement traces
  • Export as PDF, CSV or image

The ODI 3% and ODI 4% values are informational metrics derived from overnight oxygen data collected by your LOOKEE® device. They are intended for general wellness and sleep-trend tracking only. These results are not medical diagnoses and should not be used to identify or treat any health condition. If you have concerns about your breathing or sleep, please consult a qualified healthcare professional.
