My cardiologist suggests it’s a good screener for sleep apnea. Not diagnostic, but indicative that a sleep study may be necessary. He screens his patients that wear the watch for levels during sleep. If he sees consistent sub 90s he sends them off to a sleep medicine doc.
- matheusmoreira 3y agoSpO2 monitoring is one of the components of polysomnography which is used to diagnose sleep apnea. SpO2 statistics are reported in the polysomnogram: SpO2 minimum, maximum, mean, standard deviation. For example, a minimum SpO2 of 70% during sleep indicates your blood is not oxygenating properly for some reason during that period. Doesn't straight up prove it's due to sleep apnea but you can definitely assume it is and be right more often than not. The full polysomnogram also measures air flow, sleep architecture and more.
