1 gagging, coughing.
2 involuntarily resisting positive pressure ventilation in a patient with an endotracheal tube in place.
Violent resistance by a patient to intubated ventilation that may cause asynchronous breathing, ergo V/Q mismatching and risk of barotrauma, cardiac arrhythmia, and increased intracranial pressure; the newer ventilatory support devices rarely evoke this reaction, but patients may still require sedation, or narcotics
