Systematic Laryngoscopic Evaluation of Upper Airways in Ventilated ALS Patients in Portugal and in Norway

The study examines if titration of Non-Invasive mechanical ventilation (NIV) settings during ongoing laryngoscopic visualization can improve the compliance of NIV in subjects with Amyotrophic Lateral Sclerosis (ALS). The study is a multicentre study between Norwegian National Advisory Unit on Long-term Mechanical Ventilation at the Thoracic Department, Haukeland University Hospital, Bergen, Norway and Centro Hospital Tras-os-Montes e Alto Douro, Vila Real, Portugal.
