IPPVweaning techniques

Patients may require all or part of their respiratory support to be provided by a mechanical ventilator. Weaning from mechanical ventilation may follow several patterns. In patients ventilated for short periods (no more than a few days) it is common to allow 20-30min breathing on a 'T' piece before removing the endotracheal tube. For patients who have received longer term ventilation it is unlikely that mechanical support can be withdrawn suddenly; several methods are commonly used to wean these patients from mechanical ventilation. There is no strong evidence that any technique is superior in terms of weaning success or rate of weaning.
