In the third edition of the International Classification of Sleep Disorders (ICSD-3),<unk>  is classified amongst the Sleep-Related Breathing Disorders and is divided in two categories, namely adult<unk>  and pediatric<unk> .<unk>  is differentiated from central sleep apnea (CSA), which is characterized by episodes of reduction or cessation in breathing attributable to decreased effort, rather than upper airway obstruction. The respiratory effort must then be assessed in order to correctly classify the apnea as<unk>  given the specificity of the diaphragmatic activity in this condition: the inspiratory effort is continued or increased through the entire episode of absent airflow. When hypopneas are present alongside apneas, the term<unk> -Hypopnea is used and when it is associated with daytime sleepiness and other daytime symptoms, it is called<unk> -Hypopnea Syndrome. To be categorized as<unk> , the hypopnea must meet one or more of the following symptoms: (1) snoring during the event, (2) increased oronasal flow flattening, or (3) thoraco-abdominal paradoxical respiration during the event. If none of them are present during the event, then it is categorized as central hypopnea.
