Noninvasive mechanical ventilation has been suggested for the treatment of patients with respiratory failure. We describe the case of a patient affected by bilateral cystic bronchiectasis and acute hypercapnic respiratory failure, due to a cardiogenic pulmonary edema, successfully treated with bi-level nasal-CPAP. This report suggests that in some cases noninvasive ventilatory support may mean avoiding tracheal intubation, even with critically ill patients.
