MP81-03 ERECTILE DYSFUNCTION IS INDEPENDENTLY ASSOCIATED WITH APNEA HYPOPNEA INDEX & OXYGEN DESATURATION INDEX IN ELDERLY, BUT NOT YOUNGER, COMMUNITY-DWELLING MEN

Mean apnea–hypopnea duration (but not apnea–hypopnea index) is associated with worse hypertension in patients with obstructive sleep apnea

To determine which polysomnography parameters are associated with severity of hypertension.This retrospective study collected data on all patients admitted to our urban, academic center in Beijing with hypertension who had undergone polysomnograms (PSG) and were diagnosed with obstructive sleep apnea (OSA) (apnea-hyponea index [AHI] ≥5/hour). We then compared polysomnographic parameters (AHI, o...

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...

Apnea-hypopnea index, nocturnal arousals, oxygen desaturation and structural brain changes_ A population-based study

Sleep apnea has been related to brain changes such as atrophy. However, which component of sleep apnea, the apnea-hypopnea index (AHI), nocturnal oxygen desaturation or arousals, can explain this association is unclear. In this large population-based study (n1⁄4681, mean age 62.1 years), we investigated the associations of AHI, nocturnal oxygen desaturation and arousals with global and regional...

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

[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...
