“…Despite the theoretical simplicity of adding a thickening agent to a liquid to prevent airway compromise during the swallow, the successful clinical implementation of this compensatory strategy has proved challenging. Research has shown that factors such as time elapsed from mixing liquid to time of consumption, temperature of the liquid at the time of consumption, nutritional make‐up of the liquid, and type of thickening agent used to thicken the liquid can all significantly alter the resulting thickness of the liquid (Frazier et al, 2016; Garcia, Chambers, & Molander, 2005; Gosa & Dodrill, 2017; Levy, Osborn, Hasenstab, Nawaz, & Jadcherla, 2019; O'Leary, Hanson, & Smith, 2010; Payne, Methven, Fairfield, & Bell, 2011; Yoon & Yoo, 2017). Variation in resulting liquid thickness can have detrimental effects on the person with dysphagia.…”
