Oxygen via high-flow nasal cannula (HFNC) is commonly used in inpatient settings given the multiple benefits for treating respiratory distress and failure. Research investigating the impact HFNC may have on adult oropharyngeal swallowing is emerging, though limited, and with variable results. Currently, there are five available peer reviewed research articles specifically investigating oropharyngeal swallowing function in adults receiving HFNC therapy. Results/findings are inconsistent likely due to variability of each study’s subject population, design, and methods. It is important for Speech-Language Pathologists (SLPs) to appropriately integrate findings of the available research when evaluating and treating these patient populations.
