    • Airway obstruction, dynamic hyperinflation, and breathing pattern during incremental exercise in COPD patients 

      Frisk, Bente; Espehaug, Birgitte; Hardie, Jon Andrew; Strand, Liv Inger; Moe-Nilssen, Rolf; Eagan, Tomas Mikal; Bakke, Per; Thorsen, Einar (Peer reviewed; Journal article, 2014-02-01)
      Ventilatory capacity is reduced in chronic obstructive pulmonary disease (COPD) patients. Tidal volume (VT) is lower and breathing frequency higher at a given ventilation (VE) compared to healthy subjects. We examined ...

    • Change in pulmonary diffusion capacity in a general population sample over 9 years 

      Storebø, Michael Langballe; Eagan, Tomas Mikal; Eide, Geir Egil; Gulsvik, Amund; Thorsen, Einar; Bakke, Per S. (Peer reviewed; Journal article, 2016-09-02)
      Rationale: Data on the change in diffusion capacity of the lung for carbon monoxide (DLCO) over time are limited. We aimed to examine change in DLCO (ΔDLCO) over a 9-year period and its predictors. Methods: A Norwegian ...

    • Change in pulmonary diffusion capacity in a general population sample over 9 years 

      Storebø, Michael Langballe; Eagan, Tomas Mikal; Eide, Geir Egil; Gulsvik, Amund; Thorsen, Einar; Bakke, Per S. (Peer reviewed; Journal article, 2016-09-02)
      Rationale: Data on the change in diffusion capacity of the lung for carbon monoxide (DL_CO) over time are limited. We aimed to examine change in DL_CO (ΔDL_CO) over a 9-year period and its predictors. Methods: A Norwegian ...

    • Development of lung diffusion to adulthood following extremely preterm birth 

      Satrell, Emma Elsa Carolina; Clemm, Hege Synnøve Havstad; Røksund, Ola Drange; Hufthammer, Karl Ove; Thorsen, Einar; Halvorsen, Thomas; Vollsæter, Maria (Journal article; Peer reviewed, 2022)
      Background: Gas exchange in extremely preterm (EP) infants must take place in fetal lungs. Childhood lung diffusing capacity of the lung for carbon monoxide (DLCO) is reduced; however, longitudinal development has not been ...

    • The effect of low dose marine protein hydrolysates on short-term recovery after high intensity performance cycling: A double-blinded crossover study 

      Mjøs, Ingunn; Thorsen, Einar; Hausken, Trygve; Lied, Einar; Nilsen, Roy Miodini; Brønstad, Ingeborg; Edvardsen, Elisabeth; Frisk, Bente (Peer reviewed; Journal article, 2019)
      Background: Knowledge of the effect of marine protein hydrolysate (MPH) supplementation to promote recovery after high intensity performance training is scarce. The aim of this study was to examine the effect of MPH ...

    • Lung hyperinflation and functional exercise capacity in patients with COPD - a three-year longitudinal study 

      Aalstad, Linn T.; Hardie, Jon Andrew; Espehaug, Birgitte; Thorsen, Einar; Bakke, Per S.; Eagan, Tomas Mikal; Frisk, Bente (Peer reviewed; Journal article, 2018-12-06)
      Background: Lung hyperinflation contributes to dyspnea, morbidity and mortality in chronic obstructive pulmonary disease (COPD). The inspiratory-to-total lung capacity (IC/TLC) ratio is a measure of lung hyperinflation and ...

    • Peak oxygen uptake and breathing pattern in COPD patients – a four-year longitudinal study 

      Frisk, Bente; Hardie, Jon Andrew; Espehaug, Birgitte; Strand, Liv Inger; Moe-Nilssen, Rolf; Eagan, Tomas Mikal; Bakke, Per; Thorsen, Einar (Peer reviewed; Journal article, 2015-08-19)
      Background: Activities of daily living in patients with chronic obstructive pulmonary disease (COPD) are limited by exertional dyspnea and reduced exercise capacity. The aims of the study were to examine longitudinal changes ...

    • Prevalence and causes of loss of consciousness in former North Sea occupational divers 

      Sundal, Endre; Irgens, Ågot; Troland, Kari; Thorsen, Einar; Grønning, Marit (Peer reviewed; Journal article, 2013)
      Background: Loss of consciousness (LOC) is a serious event during diving. The purpose of this study wasto estimate the prevalence and causes of LOC during diving in former North Sea divers, and the impacton health-related ...

    • Risk of Misclassification of decompression sickness 

      Sundal, Endre; Grønning, Marit; Troland, Kari; Irgens, Ågot; Aanderud, Leif; Thorsen, Einar (Peer reviewed; Journal article, 2011)
      Decompression sickness (DCS) is classified on the basis of which organ system is affected, and neurological DCS is considered more severe than DCS in joints and skin with respect to response to recompression treatment and ...

    • 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 (Peer reviewed; Journal article, 2017-07-13)
      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 ...
