Name Time Method Effect of posture during one night at 13.5% O2 on normobaric hypoxia<br>1) the peripheral oxygen saturation measured continuously on the finger during sleep. The course of oxygen saturation in a horizontal and upright sleeping position are compared.<br>2) on the cognitive function, in particular the parameters speed and accuracy in the COGNITION test battery. The cognitive performance in the morning after the horizontal and the upright sleeping position are compared.
