Further study details as provided by Umeå University:

Primary Outcome Measures:
  • Core temperature [ Time Frame: One day ]
    This is an experitmetal study. Subjects receive oxygen or placebo-air during one night in random order. Outcome measure, i.e.core temperatue is measured continuously during this night with ongoing treatment of oxygen or placebo-air


Secondary Outcome Measures:
  • Sleep stages, apnea-hypopnea index [ Time Frame: One day ]
    This is an experitmetal study. Subjects receive oxygen or placebo-air during one night in random order. Outcome measure, i.e.the amount of differernt sleep stages, total sleep time and apnea-hypopnea index is measured during this night with ongoing treatment of oxygen or placebo-air
