: Current knowledgeCurrent practice of respiratory secretion suctioning in subjects with endotracheal tubes or tracheostomy cannulas consists of insertion of a sterile catheter. This maneuver is frequently associated with pain and agitation and traumatic injury to the tracheobronchial mucosa and occasionally causes more severe, life-threatening complications. It is also relatively inefficient, because it only aspirates proximal airway secretions.What this paper contributes to our knowledgeThis paper provides the first set of data about the safety of an alternative technique, called mechanical insufflation-exsufflation (MIE), with the potential of being well tolerated and more effective. The device applies positive pressure followed by an abrupt fall to negative pressure, thereby imitating cough and generating outward flow. We did not detect any adverse event in the present small study, in which we attempted airway secretion clearance with MIE. MIE was well tolerated and produced respiratory secretions in all except one of the suctioning attempts.
