Videoradiographic Analysis of How Carbonated Thin Liquids and Thickened Liquids Affect the Physiology of Swallowing in Subjects with Aspiration on Thin Liquids

Abstract

Carbonated liquids reduced penetration/aspiration into the airways, reduced pharyngeal retention and pharyngeal transit time became shorter. Therefore, carbonated liquids are a valuable treatment option for patients with penetration/aspiration. Thickened liquids may still be an option for patients who cannot tolerate carbonated liquids and liquids with this consistency are safer than thin liquids.
