[Noninvasive mechanical ventilation in acute respiratory failure].

Mechanical ventilation is the essential treatment for acute respiratory failure. The methods used differ greatly depending on whether one chooses invasive or noninvasive. Noninvasive ventilation avoids orotracheal intubation, facilitates weaning and, if negative pressure ventilation is integrated with positive pressure ventilation, the majority of patients will not need intubated. The ideal setting for mechanical ventilation, where possible, is the Respiratory Intensive Care Unit.
