Fig. 2From: Hypoxia-induced lowered executive function depends on arterial oxygen desaturationRepresentative photo of experimental manipulation. In all conditions, participants breathed sample gases from a mask that was connected to Douglas bags. Heart rate (HR) by heart rate monitor and percutaneous arterial oxygen saturation (SpO2) by a pulse oximeter placed on the left earlobe were monitored every minute. Participants performed the CWST after 10 min exposing to each gasBack to article page
