Active Sleep: The Active stages of sleep are the lightest. During REM we dream vividly and our bodies remain still. Children are more active than adults in REM sleep and have variable breathing patterns.
Arousal: An abrupt change from “deeper” stage of sleep to a “lighter” stage, or from REM sleep toward wakefulness, with the possibility of awakening at the final outcome.
Breathing Disruption: An event that disrupts your natural breathing pattern and can potentially affect your sleep quality.
Central Apnea: Caused by a lack of a brain signal to muscles and last about 20 seconds. A few of these per night is normal, particularly in children and at the moment of falling asleep.
Hypopneas: Characterized as shallow breathing caused by a narrow airway.
Obstructive Apnea: Characterized by a pause in breathing caused by a closed airway.
School Night: Sunday through Thursday are considered school nights.
Still Sleep: The deepest stage of sleep. Children in this stage are completely still with a consistent breathing pattern.
Sleep Apnea: A potentially serious sleep disorder in which breathing repeatedly affects your overall sleep quality.
Sleep Efficiency: Is the first metric for understanding your child's sleep by understanding how much sleep your child gets during their sleep period. A lower sleep efficiency typically is related to a higher number or longer duration of wake ups. Typically a child's sleep efficiency should fall between 92-98%.
Sleep Latency: The measure of how long it takes your child to fall asleep after bedtime. Sleep latency is a good indicator of if your child is going to sleep at the right time. Typically a child's normal sleep latency is between 5-30 minutes.
Sleep Quality: Measurement of all of the stages of sleep and if you are progressing through these stages naturally. Factors that are measured:
1. Amount of time spent in bed.
2. Amount of time spent in deep sleep.
3. Consistency of the sleep.
4. Amount of times where the app registered you as fully awake.
Sleep Quantity: The amount of time your child needs to be asleep.
Total Sleep: This is equivalent to the "night's sleep" if your child no longer takes naps.
Total Sleep Time: The amount of actual sleep time in a sleep episode; this time is equal to the total sleep episode subtracting the awake time. TST is the total of all REM and NREM sleep in a sleep episode.
Wake up: Counted as when your child has woken up from sleep or an out of bed event
Weekend: Friday and Saturday are considered the weekend.
