      Benestad, Merete R.; Drageset, Jorunn; Clemm, Hege Synnøve Havstad; Røksund, Ola Drange; Vollsæter, Maria; Halvorsen, Thomas; Hysing, Mari; Vederhus, Bente Johanne (Peer reviewed; Journal article, 2021)
      Background: Exercise-induced laryngeal obstruction (EILO) is common in young people with exertional breathing difficulties. Psychological characteristics have been proposed as underlying contributors; however, the evidence ...
    • Severe exercise-induced laryngeal obstruction treated with supraglottoplasty 

      Sandnes, Astrid; Hilland, Magnus; Vollsæter, Maria; Andersen, Tiina Maarit; Engesæter, Ingvild Øvstebø; Sandvik, Lorentz; Heimdal, John-Helge; Halvorsen, Thomas; Eide, Geir Egil; Røksund, Ola Drange; Clemm, Hege Synnøve Havstad (Journal article; Peer reviewed, 2019)
      Introduction: Exercise induced laryngeal obstruction (EILO) is relatively common in adolescents, with symptoms often confused with exercise induced asthma. EILO often starts with medial or inward rotation of supraglottic ...
    • Tailoring NIV by dynamic laryngoscopy in a child with spinal muscular atrophy type I 

      Vollsæter, Maria; Skjoldmo, Anett; Røksund, Ola Drange; Hilland, Magnus; Andersen, Tiina Maarit (Peer reviewed; Journal article, 2021)
      Dynamic laryngoscopy during noninvasive (NIV) respiratory therapy is feasible and may facilitate optimal and individualized treatment in patients with chronic respiratory failure, also in children.
    • Tracking of lung function from 10 to 35 years after being born extremely preterm or with extremely low birth weight 

      Bårdsen, Tonje; Røksund, Ola Drange; Benestad, Merete; Hufthammer, Karl Ove; Clemm, Hege Synnøve Havstad; Mikalsen, Ingvild Bruun; Øymar, Knut Asbjørn Alexander; Markestad, Trond Jacob; Halvorsen, Thomas; Vollsæter, Maria (Peer reviewed; Journal article, 2022)
      Background Lifelong pulmonary consequences of being born extremely preterm or with extremely low birth weight remain unknown. We aimed to describe lung function trajectories from 10 to 35 years of age for individuals born ...
    • Use of inhaled ipratropium bromide to improve exercise-induced laryngeal obstruction cannot be recommended 

      Muralitharan, Praveen; Carlsen, Petter; Hilland, Magnus; Delestre-Levai, Irisz; Vollsæter, Maria; Hufthammer, Karl Ove; Engan, Mette; Røksund, Ola Drange; Halvorsen, Thomas; Clemm, Hege Synnøve Havstad (Peer reviewed; Journal article, 2023)
      Introduction: Exercise-induced laryngeal obstruction (EILO) is a common cause of exertional breathing problems in young adults. Current management generally consists of breathing advice, speech therapy, inspiratory muscle ...
    • Ventilatory efficiency and aerobic capacity in people with multiple sclerosis: A randomized study 

      Riksfjord, Stine Maren Langholm; Brændvik, Siri Merete; Røksund, Ola Drange; Aamot, Inger Lise (Journal article; Peer reviewed, 2017)
      Objectives: To assess ventilatory efficiency and aerobic capacity in people with multiple sclerosis and whether treadmill walking or progressive strength training has an effect on these parameters in this population. ...
    • Ventilatory efficiency in children and adolescents born extremely preterm 

      Hestnes, Julie; Hoel, Hedda Benedicte; Risa, Ole J.; Romstøl, Hanna O.; Røksund, Ola Drange; Frisk, Bente; Thorsen, Einar; Halvorsen, Thomas; Clemm, Hege Synnøve Havstad (Journal article; Peer reviewed, 2017)
      Purpose: Children and adolescents born extremely preterm (EP) have lower dynamic lung volumes and gas transfer capacity than subjects born at term. Most studies also report lower aerobic capacity. We hypothesized that ...
    • Voice and Exercise Related Respiratory Symptoms in Extremely Preterm Born Children After Neonatal Patent Ductus Arteriosus 

      Engeseth, Merete Salveson; Engan, Mette; Clemm, Hege Synnøve Havstad; Vollsæter, Maria; Nilsen, Roy Miodini; Markestad, Trond Jacob; Halvorsen, Thomas; Røksund, Ola Drange (Peer reviewed; Journal article, 2020)
      Objective: To investigate voice characteristics and exercise related respiratory symptoms in extremely preterm born 11-year-old children, focusing particularly on associations with management of a patent ductus arteriosus ...
    • Working Towards a Common Transatlantic Approach for Evaluation of Exercise-Induced Laryngeal Obstruction 

      Røksund, Ola Drange; Olin, James Tod; Halvorsen, Thomas (Journal article; Peer reviewed, 2018)
      Key points: • The history is the key to a correct exercise-induced laryngeal obstruction (EILO) diagnosis, with inspiratory symptoms presenting during ongoing exercise and resolving within a few minutes after exercise ...
