The study investigates how high flow nasal cannula (HFNC) affects swallowing function and safety, specifically looking for flow rates that allow safe swallowing.
Healthy participants underwent swallowing function assessments using Flexible Endoscopic Evaluation of Swallowing (FEES), testing various textures and HFNC flow rates (0-60 LPM).
Results indicate that high flow rates do not significantly impact swallow safety, though a small percentage of unsafe swallows were recorded at the highest flow rate for a specific trial.
