Jоhn, а 20 yeаr оld mаle, is admitted tо the hospital with a persistent cough and shortness of breath after being diagnosed with acute bronchitis a month ago. His family noticed he began coughing on solid food several days ago so he has been eating solid foods and soups. In the hospital, he was found to have atrial fibrillation and congestive heart failure with significant edema/swelling in his extremities and systemic inflammatory response syndrome. During a clinical swallow evaluation, John continued to cough on solid textures but did not cough with liquids and purees. He was unable to pass the 3 oz water challenge using the Yale Swallow Protocol. What would you recommend as the next step in his assessment and treatment?
