Dear Editor,

There is increasing interest in complications of critical illness, which may play a major role in lengthening the duration of hospitalization [ 1]. Between 42 and 60% of critically ill patients have disordered swallowing (dysphagia) following extubation, with duration of endotracheal intubation recognized as a risk factor [ 2]. Endotracheal intubation of more than 6 days has been associated with an increased incidence and severity of dysphagia [ 3]. Much of the current data on post-extubation dysphagia are inferred from subjective assessments of pulmonary aspiration (radiography/nasoendoscopy), and mechanistic swallow information is lacking. High-resolution pharyngeal manometry, a catheter-based assessment, provides objective biomechanical data and quantifies bolus movement and muscle contraction/relaxation along the pharynx during swallowing (Fig.  1a, b) [ 4, 5]. We utilized this test in critically ill patients to determine the impact of the duration of endotracheal...
