Non invasive ventilation for acute respiratory failure • Reduces the complications associated with mechanical ventilation • Improves the outcome of COPD exacerbations and cardiogenic pulmonary edema • A careful use in hypoxemic respiratory failure may be interesting • NIV represents an interesting therapy when intensity of therapy is limited
