Swallowing has an important function in the lives of individuals, it is related to moments of socialization, pleasure, nutrition and also helps protect against the entry of food, saliva or other material towards the lungs (penetration and/or laryngotracheal aspiration). A Difficulty in swallowing is called dysphagia and therapeutic strategies are necessary to help the affected individuals. The use of carbonated water as a therapeutic strategy has been used, however, there are still few studies on the topic. In the search for therapeutic strategies viable and easy to insert into the clinical routine and daily lives of patients, this study aims to verify the effect of carbonated water on swallowing liquids for patients with dysphagia diagnosed by videodeglutogram examination, through comparison with non-water carbonated. The present study aims to generate scientific evidence about the effect of water carbonated drink as a strategy in patients with liquid dysphagia, with the aim of helping professional speech therapist and other professionals involved in the therapeutic process, in order to improve the health and quality of life of dysphagic patients and contribute to the evolution of knowledge in the field of dysphagia. This is a clinical trial, all participants will be included adult patients to carry out the video swallow examination, which present aspiration and/or laryngotracheal penetration of liquids during the performance of the and who agree to participate in the research. The effect of carbonated water on levels of penetration and/or laryngotracheal aspiration in relation to the use of non-carbonated water, and analyzed whether the results obtained with the use of carbonated water have behavior similar between the different patient profiles studied.
