Could hyperoxic ventilation impair oxygen delivery in septic patients?
In critically ill patients, a decrease in whole body oxygen consumption under hyperoxia has been reported and this could be related to hyperoxia-induced arterial changes. We investigated changes in brachial artery circulation and tone during short-term hyperoxic ventilation in septic patients. ⋯ Hyperoxia was paradoxically demonstrated to decrease oxygen delivery in upper limbs during septic shock.
