[Non invasive ventilation in emergency settings].

The use of non invasive ventilation (NIV) in the emergency setting to treat acute respiratory failure (ARF) has received much attention. To date, large studies support the early administration of continuous positive airway pressure (CPAP) in patients with cardiogenic acute pulmonary edema; and 2) non-invasive positive pressure ventilation (NPPV) for exacerbations of chronic obstructive pulmonary disease (COPD). NIV could also be useful in other types of ARF, but its success rate is dependent on the cause of ARF and patient's characteristics. Use of NIV in the emergency setting should take into account validated indications and local expertise of the nursing staff to minimize the risk of complications.
