[Overnight polysomnography versus respiratory polygraphy in the diagnosis of pediatric obstructive sleep apnea].

The French Society of Research and Sleep Medicine (SFRMS) organized a meeting on obstructive sleep apnea syndrome (OSAS) in children. A multidisciplinary group of specialists (pulmonologists, ENT surgeons, pediatricians, neurophysiologists, sleep specialists) drew up a consensus document on the value of electrophysiological recordings in the diagnosis of OSAS in children. Technical considerations and recommended sensors, respiratory event definitions, and scoring criteria are presented according to the 2012 and 2014 recommendations of the American Academy of Sleep Medicine (AASM). Polysomnographic criteria for sleep-disordered breathing in children and the French National Authority for Health guidelines for indications of polysomnographic studies were reported. Relevance and limits of in-lab PSG, home PSG, and respiratory polygraphy were presented and guidelines were proposed to improve the diagnosis and follow-up of these children.
