4 liters of oxygen a minute

Air from a placebo oxygen delivery

Other

4 liters a minute of air from a placebo device

Primary outcomes

  1. 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 outcomes

  1. 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
