简要总结
To compare preoxygenation for induction of general anaesthesia with High Flow Nasal Cannula vs preoxygenation with face mask in patients undergoing bariatric surgery. The hypothesis is that preoxygenation with High Flow Nasal Cannula prolongs normoxia time during induction of anaeshesia and is superior to conventional preoxygenation with face mask. Primary endpoint will be the time during which spO2 > 92 %. Secondary endpoint will be paCO2.
