Crossectional Study on the Performance of Screening Questionnaires for Prediction of Moderate to Severe Obstructive Sleep Apnea in Women.

 The clinical manifestations of obstructive sleep apnea (OSA) are different between genders. Though there are several screening questionnaires for OSA, their performance in females is not fully understood, as women have been historically underrepresented in research studies.  To assess the performance of screening questionnaires and their capacity to identify a moderate to severe apnea-hypopnea index (AHI) in women.

Performance of the NOSE Questionnaire in Mask Selection for Home CPAP Titration.

 Many patients abandon CPAP treatment because they find the mask uncomfortable. Therefore, specialists may benefit from the predictive value of airway assessment tools.  To identify nasal ventilation failure through the Nasal Obstruction Symptom Evaluation (NOSE) scale in patients with obstructive sleep apnea (OSA) who undergo home-based auto-adjusting CPAP titration and to determine whether there is a correlation between NOSE score and the type of mask selected.

The Cervical Fat Tissue Volume is a Predictor for Moderate to Severe OSA.

 Obstructive sleep apnea (OSA) is a disorder characterized by recurrent pharyngeal obstruction during sleep, in which upper airway anatomy plays a key role in its pathogenesis. The aim of this study was to describe whether the quantification of cervical fat tissue volume (CFTV) obtained by Computed Tomography (CT)cephalometry is related to the severity of OSA.  Retrospective study between 2018 and 2020 in those patients > 18 years old, with diagnosis of OSA who performed a volumetric cephalometric imaging.

Compliance to Continuous Positive Airway Pressure therapy in patients with obstructive sleep apnea - long-term assessment.

Introduction: To assess CPAP acquirement, compliance, and dropout rates among OSA patients three years after the prescription.

Material And Methods: We assessed CPAP acquirement (Acq), compliance (Comp), and dropout (Dout) through a telephone survey. We interviewed 156 patients; ESS: 9.

Contribution of pulse oximetry in relation to respiratory flow events in a home-based approach aimed at diagnosing obstructive sleep apnea.

Objective: To compare pulse oximetry with manual analysis against all signals of respiratory polygraphy.

Material And Methods: This retrospective study estimated sensitivity (S), specificity (Sp) and positive/negative likelihood ratio (LR+/-) of the oxygen desaturation index (ODI-test) and apnea-hypopnea index (AHI-reference).

Results: 3854 patients (61.

CPAP indication based on clinical data and oximetry for patients with suspicion of obstructive sleep apnea: A multicenter trial.

Background And Objective: The usefulness of pulse oximetry for the management of obstructive sleep apnea is controversial. The aim of this study was to assess the accuracy for indication of Continuous Positive Airway Pressure (CPAP) treatment in patients with suspected obstructive sleep apnea (OSA) based on clinical and oximetry data as compared to polysomnography (PSG).

Methods: This multicenter observational study involved seven sleep laboratories.

Simulated intention-to-treat analysis based on clinical parameters of patients at high risk for sleep apnea derivated to respiratory polygraphy.

Purpose: Obstructive Sleep Apnea-Hypopnea Syndrome (OSAS) is a public health problem. We designed a pilot study to validate empiric indication of CPAP therapy in a population with moderate-to-high pre-test probabilities who underwent self-administered home-based respiratory polygraphy (RP).

Methods: A cross-sectional simulation study was performed.

Sleep respiratory disturbances during the ascent to Mount Aconcagua.

Introduction: Mountaineers exposed to hypobaric hypoxia (HH) show high-altitude periodic breathing (PB).

Objective: To analyze high-altitude PB during the ascent of Mount Aconcagua (Argentina).

Materials And Methods: Descriptive study in healthy volunteers using respiratory polygraphy (RP) at different altitudes.
