BACKGROUND: Catheter suctioning of respiratory secretions in intubated subjects is limited to the proximal airway and associated with traumatic lesions to the mucosa and poor tolerance. "Mechanical insufflation-exsufflation" exerts positive pressure, followed by an abrupt drop to negative pressure. Potential advantages of this technique are aspiration of distal airway secretions, avoiding trauma, and improving tolerance. METHODS: We applied insufflation of 50 cmH2 O for 3 s and exsufflation of - 45 cmH2 O for 4 s in patients with an endotracheal tube or tracheostomy cannula requiring secretion suctioning...
