Preliminary experience on the safety and tolerability of mechanical "insufflation-exsufflation" in subjects with artificial airway.

ABSTRACT: 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 cmH2O for 3 s and exsufflation of - 45 cmH2O for 4 s in patients with an endotracheal tube or tracheostomy cannula requiring secretion suctioning. Cycles of 10 to 12 insufflations-exsufflations were performed and repeated if secretions were aspirated and visible in the proximal artificial airway. Clinical and laboratory parameters were
