| O | Obesity–Hypoventilation Syndrome is the name of a health condition, which is directly related to Obstructive Sleep Apnea, in which people, who suffer from extreme obesity, are not able to breathe sufficient air during their sleep, as well, as when they are awake.
Obstructive Apnea is the kind of Apnea, which occurs because of a mechanical obstruction, for example because of an excessively large uvula or tongue in the back of the mouth, and / or because of some problems with the trachea.
Obstructive Sleep Apnea is the sleep disorder, when the process of breathing gets interrupted for short intervals during sleep. This condition usually results in intermittent decreases in blood oxygen levels and transient arousals from sleep, which, in its order, leads to poor quality of sleep and to an excessive daytime sleepiness.
Orexin is the term, which is applied to a protein neurotransmitter or neuropeptide that works during the sleep cycle and in appetite. There are two kinds of peptides, comprised in the peptide family: Orexin – A (hypocretin – 1) and Orexin – B (hypocretin – 2). In case if a person suffers from the Orexin deficiency, it is usually associated with narcolepsy.
OSLER (Oxford Sleep Resistance Test) – is the test, which is designed as an objective vigilance test, and it is similar to MSLT, though, it does not include EEG monitoring in the sleep cycle and in appetite.
