Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: High-flow nasal cannula (HFNC) is a non-invasive heated and humidified oxygen delivery device that is capable of delivering high-flow rates. It is a relatively new modality that has been introduced as an alternative to conventional oxygen therapy. The clinical value of the use of HFNC is not limited to its ventilation and oxygenation effects, it enables the patient to talk and is purported to permit oral feeding during oxygen therapy despite the limited evidence regarding its impact on swallow function. This study will determine the impact of different flow rates of a high-flow nasal cannula on spontaneous swallowing frequency at rest and swallowing effort and timing while swallowing. Methods: This is a prospective study designed to measure swallowing frequency and swallowing effort in fifty healthy adult volunteers. Participants will receive three levels of HFNC flow rates (30, 45, and 60 L/min) through nasal prongs. The study participants will be asked to swallow measured amounts of water and applesauce and subjected to each flow rate for 15 minutes. Swallowing effort measurement through surface electromyography (sEMG) will be recorded at baseline and the three levels of HFNC flow rates interventions.
