Complications are limited and most can be quickly remedied by removing nasal cannula
If not well-positioned/attached, may complicate laryngoscopy
High flow oxygen from nasal cannula is cold and dry; may not be well-tolerated by patient
Extremely high flow oxygen (>70 L/M) may cause barotrauma
Increased apnea time increases respiratory acidosis
Not shown to improve saturation in critically ill patients
