[Highlights of the 55th SEPAR Congress].

The 55th SEPAR Congress was held in Pamplona from 2 to 4 of June 2022. Once again, it was the referral scientific meeting for specialists in pulmonology, thoracic surgery, nursing, physiotherapy, paediatric respiratory diseases and other disciplines involved in respiratory care. The Spanish Society of Pulmonology and Thoracic Surgery showed its national and international leadership in the management of respiratory diseases, which was reflected in a program with an excellent content and a high scientific level.

Monitoring Noninvasive Ventilation in Patients with Obesity Hypoventilation Syndrome: Comparison between Ventilator Built-in Software and Respiratory Polygraphy.

Background: Polygraphy (PG) remains the standard method of assessing noninvasive ventilation (NIV) effectiveness. Built-in software (BIS) of recent NIV equipment provides estimates of some ventilator parameters, but their usefulness is unclear.

Objectives: To assess the reliability of BIS compared with PG in a cohort of obesity hypoventilation syndrome (OHS) patients on NIV.

Snoring as a Determinant Factor of Oxidative Stress in the Airway of Patients with Obstructive Sleep Apnea.

Purpose: In obstructive sleep apnea-hypopnea syndrome (OSAS), airway collapses and vibrations cause local and systemic inflammatory response and oxidative stress (OS). Our objective was to determine the presence of OS in the airway of patients with OSAS compared with controls without OSAS and determine its relation to treatment with CPAP and other clinical variables.

Method: We performed a prospective observational case-control study with repeated measures.
