Utility of Acoustic Pharyngometry for the Diagnosis of Obstructive Sleep Apnea

摘要: Rationale: Owing to resource limitations, the testing of patients for obstructive sleep apnea (OSA) is often delayed. There a need accurately triage and expedite in those with high pretest probability OSA. Acoustic pharyngometry simple, noninvasive technique used assess upper airway cross-sectional area (UA-XSA), which known be reduced OSA.Objectives: To determine discriminative ability predictive value UA-XSA measurements by acoustic OSA.Methods: We conducted study clinical cohort consecutive adults suspected OSA who had undergone both polysomnography pharyngometry. was defined as an apnea–hypopnea index greater than or equal 5. Multivariable logistic regression analyses receiver operating characteristic curves were used.Measurements Main Results: The included 576 subjects, 87% whom 64% men. subjects’ median body mass (BM...
