High Flow vs Conventional Oxygen in Head and Neck Surgery

The AIRVO 2 is for the treatment of spontaneously breathing patients who would benefit from receiving high flow warmed and humidified respiratory gases. The subjects in this group will receive HFOT at a flow rate of 60-30L liters per minute, maximum concentration of 40%, which will be titrated by bedside nurse to maintain an oxygen saturation of 92% or greater (unless there is a history of COPD and then the clinician can recommend \>88%)

Subjects will be placed on aerosolized trach mask with cool humidification, and titrated to keep oxygen saturation \>92% (unless there is a history of COPD and then the clinician can recommend \>88%)
