To quantify the incidence and degree of endotracheal tube intraluminal obstruction after mechanical ventilation and its relation to time of intubation. Prospective observational study. A 14-bed medical-surgical intensive care unit at a university-affiliated teaching hospital. Ninety-four endotracheal tubes used in 80 patients requiring mechanical ventilation for more than 12 h. Acoustic reflectometry was performed in every endotracheal tube after patient extubation to measure its volume… CONTINUE READING
