Quantitative Analysis of Thoracoabdominal Asynchrony in Pediatric Polysomnography

摘要

Study Objectives:Objective measurements of thoracoabdominal asynchrony (TAA), such as average phase angle (θavg), can quantify airway obstruction. This study demonstrates and evaluates use of θavg for predicting obstructive sleep apnea (OSA) in pediatric polysomnography (PSG).
