HERNANDEZ-LOPEZ, Guillermo David et al. Weaning from mechanical ventilation. Med. crít. (Col. Mex. Med. Crít.) [online]. 2017, vol.31, n.4, pp.238-245. ISSN 2448-8909.

The majority of patients requiring ventilation> 24 hours and improving can be extubated after the first spontaneous ventilation test. The challenge is to improve the disconnection of patients who fail. The withdrawal of mechanical ventilation is an essential element in the care of critically ill patients. The process of releasing the patient from the mechanical support and the endotracheal cannula is reviewed. The time spent in the weaning process represents 40 to 50% of the total duration of ventilation. It is recommended: 1) Predict three groups depending on the difficulty and duration of weaning, 2) Removal as soon as possible, 3) Using the spontaneous ventilation test to determine if patients can be successfully extubated, 4) The initial test Should last 30 minutes in T-tube breathing or with low levels of support, 5) Support pressure and modes of AC ventilation should be preferred when they failed in the first test, 6) Consider non-invasive ventilation in selected patients to shorten The duration of intubation, but should not be routinely used as a tool for the failure of extubation.
