Compared to other methods of respiratory failure treatment, heated high-flow oxygen (HHO2) therapy is relatively new. The HHO2 system enables the delivery of high oxygen flow improving patient respiration and ventilation, therefore avoiding the need for more invasive ventilation methods. The patient population requiring HHO2 therapy is heterogeneous. We will review this therapeutic approach including its: goals, physiological benefits, limitations, and potential effect on the swallow. Very little is known about swallowing physiology across many pulmonary conditions including the effect of HHO2 on swallowing biomechanics. Due to the medical fragility of this diagnostic subgroup and the relative lack of evidence guiding the assessment and management of their swallow, clinicians must proceed cautiously.
