Pediatric Obstructive Sleep Apnea Diagnosis by Respiratory Polygraphy

Sponsor: Central Hospital, Nancy, France

Summary

Respiratory polygraphy (RP) can be used to detect obstructive sleep apnea syndrome in children (OSA) , but it underestimates the obstructive apnea-hypopnea index (OAHI) because hypopneas associated with cortical arousals are not evaluated. To compensate for this disadvantage, hypopneas linked with autonomic micro-arousals can be calculated from the drop in pulse wave amplitude (obtained dy oximetry), as increased respiratory efforts are related to autonomic nervous system activation, tachycardia, and elevated blood pressure. The aim of this study is to compare OAHI obtained by RP alone or by RP considering hypopneas associated with autonomic micro-arousals with OAHI by polysomnography (PSG).
