Perioperative hypoxemia
Conditions
Interventions
High-flow nasal cannula (HFNC) group:Patients in the HFNC group received oxygen (set temperature at 37°C, oxygen concentration at 100%, oxygen flow rate at 20 L/min before anesthesia, and increased to
Panmure, Auckland, New Zealand).
Nasal cannula (NC) group:Patients in the NC group also received oxygen via an OptiFlow THRIVE device (set temperature to room temperature, oxygen concentration at 100%, oxygen flow rate at 6 L/min bef
