Abstract: The use of high flow nasal oxygen (HFNO) in clinical practice is increasing with robust evidence of its respiratory benefits. Swallowing is known to be heavily coordinated with breathing, in addition to sharing a physical pathway in the upper airway. Applying HFNO via these spaces may also have an impact on the swallowing process. Yet, there is a lack of literature regarding the effect of HFNO on swallowing and on dysphagia. This narrative review aims to summarise the existing literature, draw conclusions on important clinical questions where possible and set the scene for future research.
