      Engan, Mette; Jansrud, Ida; Bekken, Marianne; Halvorsen, Thomas; Fretheim-Kelly, Zoe Louise; Vollsæter, Maria; Bovim, Lars Peder Vatshelle; Røksund, Ola Drange; Clemm, Hege Havstad (Peer reviewed; Journal article, 2021)
      Aims: A cardiopulmonary exercise test (CPET) is the gold standard to evaluate symptom-limiting exercise intolerance, while continuous laryngoscopy performed during exercise (CLE) is required to diagnose exercise-induced ...
    • Reliability of translaryngeal airway resistance measurements during maximal exercise 

      Fretheim-Kelly, Zoe; Engan, Mette; Clemm, Hege Synnøve Havstad; Andersen, Tiina Maarit; Heimdal, John-Helge; Strand, Eric; Halvorsen, Thomas; Røksund, Ola Drange; Vollsæter, Maria (Peer reviewed; Journal article, 2022)
      Objective: Exercise-induced laryngeal obstruction is an important cause of exertional dyspnoea. The diagnosis rests on visual judgement of relative changes of the laryngeal inlet during continuous laryngoscopy exercise ...
    • Use of inhaled ipratropium bromide to improve exercise-induced laryngeal obstruction cannot be recommended
