Prediction of obstructive sleep apnea: comparative performance of three screening instruments on the apnea-hypopnea index and the oxygen desaturation index

Is Apnea-Hypopnea Index a proper measure for Obstructive Sleep Apnea severity?

Tongue Volume Influences Lowest Oxygen Saturation but Not Apnea-Hypopnea Index in Obstructive Sleep Apnea

OBJECTIVES The aim of this study was to identify correlations between sleep apnea severity and tongue volume or posterior airway space measured via three-dimensional reconstruction of volumetric computerized tomography (CT) images in patients with obstructive sleep apnea (OSA) for use in predicting OSA severity and in surgical treatment. We also assessed associations between tongue volume and M...

[Agreement between oxygen desaturation index and apnea-hypopnea index in adults with suspected obstructive sleep apnea at an altitude of 2240 m].

OBJECTIVE Altitude can affect the diagnostic accuracy of portable monitors used to diagnose suspected obstructive sleep apnea syndrome on the basis of oxygen desaturation measurements. The aim of this study was to determine agreement between the desaturation index measured by oximetry and the apnea-hypopnea index measured by polysomnography in Mexico City (2240 m above sea level). We also wishe...

Outcome measurements in obstructive sleep apnea: beyond the apnea-hypopnea index.

OBJECTIVES/HYPOTHESIS The apnea-hypopnea index (AHI) is overwhelmingly used as the main therapeutic metric in the assessment of obstructive sleep apnea (OSA) in surgical studies. However, using AHI as the sole measure is problematic. This study investigates the utility of other outcome measures for patients with OSA undergoing surgery. STUDY DESIGN Systematic review of cohort and review studi...
