What is a normal oxygen desaturation index?
At sea level, a normal blood oxygen level (saturation) is usually 96 – 97%. Although there are no generally accepted classifications for severity of oxygen desaturation, reductions to not less than 90% usually are considered mild. Dips into the 80 – 89% range can be considered moderate, and those below 80% are severe.
What is a normal spontaneous arousal index?
Normal reported values range from 5±2 to 10.8±4.2 for children,3 and the AASM Pediatric Task force has recommended an arousal index of < 14 per hour of sleep as normal for a prepubertal child in a sleep laboratory, taking first-night effect into account.

Why am I waking up with delusions?
Confusional arousals is considered a parasomnia. This type of sleep disorder involves unwanted events or experiences that occur while you are falling asleep, sleeping, or waking up. Episodes tend to occur as you wake from slow-wave or stage N3 sleep. This sleep stage is most common in the first third of the night.
What is an abnormal oxygen desaturation index?
Scoring Guidelines. Normal oxygen saturation should be 96 to 97%. A drop below 90% is considered mildly abnormal, between 80 to 89% is considered moderately abnormal, and below 80% is considered severely abnormal. 3.
What is normal desaturation during sleep?
Normal saturation is around 95 percent. A desaturation to 86 percent is mild, a reduction to 80 to 85 percent is moderate, and a drop to 79 percent or less is severe.
What causes spontaneous arousals during sleep?
The arousals and awakenings that occur when things go awry in your breathing while you’re asleep can arise from a glitch in the central nervous system–i.e., the brain “forgets” to breathe–but more commonly have a mechanical cause.
What is Hypnopompia?
Hypnopompic hallucinations are hallucinations that occur in the morning as you’re waking up1. They are very similar to hypnagogic hallucinations, or hallucinations that occur at night as you’re falling asleep. When you experience these hallucinations, you see, hear, or feel things that aren’t actually there.
What does arousal mean in the state of sleep?
Arousal Signifies Changes in the State of Sleep. Sleep occurs in two basic states throughout the night. The two stages of sleep are rapid eye movement sleep (REM) and nonrapid eye movement sleep (NREM). REM is a deep stage of sleep with intense brain activity in the forebrain and midbrain.
What does arousal mean in terms of EEG?
Arousal is an abrupt change in the pattern of brain wave activity, as measured by an EEG. Arousal typically represents a shift from deep sleep, which is commonly known as REM sleep, to light sleep, known as NREM sleep, or from sleep to wakefulness.
When do you become aroused during the sleep cycle?
Arousal typically represents a shift from deep sleep, which is commonly known as REM sleep, to light sleep, known as NREM sleep, or from sleep to wakefulness. As it sounds, arousal is when a person becomes ‘aroused’ to some extent during the sleep cycle.
What does it mean when a child has arousal disorder?
Arousal Disorders in Children. Arousal disorders are common in children. Arousal does not mean that the child wakes-up. The “arousal” is a partial arousal usually from “deep” sleep also called “slow wave sleep”. Most commonly the child transitions from deep sleep to a mixture of very light sleep and/or partial wakefulness.
