Answer

Noninvasive ventilation can ameliorate some of the pathophysiologic derangements that occur following extubation and has been used in 2 primary postextubation scenarios. Patients in whom weaning trials have failed or those who do not meet extubation criteria have been extubated to noninvasive ventilation support as part of an early extubation approach or as an adjunct to weaning. Early extubation with noninvasive ventilation support may be able to prevent some of the complications associated with endotracheal intubation, specifically nosocomial pneumonia. In addition, noninvasive ventilation allows for speech with preservation of oropharyngeal function. Noninvasive ventilation has also been applied to patients who were identified as candidates for extubation based on weaning and/or extubation criteria but then developed postextubation respiratory distress.
