Iatrogenic aspiration of components of respiratory care equipment.

Two cases of airway foreign bodies involving the aspiration of component parts of commonly used respiratory therapy equipment are described. The first case demonstrated the accidental introduction of a washer from a closed catheter suction system into the airway of a patient. The second case involved the accidental introduction of a part of an intubating stylet into the lung. Improper use of this equipment can result in airway foreign bodies and potential respiratory compromise.
