- Real Sleep Time—measures actual time asleep—not just time in bed, like other home devices, providing a more accurate assessment of sleep apnea.
- RDI and AHI—special indices that determine the severity of sleep apnea.
- ODI (Oxygen Desaturation Index)—measurement of blood oxygen levels. When not enough oxygen reaches the brain, a person awakens from sleep.
- Heart Rate—the number of heart beats per minute while sleeping.
- Body Position—notes whether you sleep on your back (supine), front (prone) or side, all which influence apnea.
- Snoring Intensity (dB)—loud snoring is a major indicator of sleep apnea.
- Sleep Stages and Architecture (wake/light/deep)—the cyclical pattern of various NREM and REM sleep stages summarized in a chart called a hypnogram.
- REM/NREM Sleep—dreaming sleep characterized by rapid eye movement (REM), the shortest portion of the sleep cycle; Non-REM (NREM) sleep, the largest portion of the sleep cycle, has three separate stages and distinct electrical brainwave patterns.
- Sleep Fragmentation—repeated short interruptions of sleep throughout the night, reducing the total amount of time spent in the deepest level of sleep.
