[Noninvasive ventilation]

Endotracheal intubation and mechanical ventilation have traditionally been employed in patients with acute respiratory insufficiency. However, this form of management can have serious adverse effects, mainly infections and barotrauma. Noninvasive ventilation (NIV) has been shown to be an effective alternative, as it reduces both the frequency of complications and cost of care. In fact, NIV is currently the first choice treatment for acute respiratory insufficiency in patients who have chronic obstructive pulmonary disease or who are immunocompromised. It is also commonly applied in patients with asthma, pneumonia, and acute cardiogenic pulmonary edema. Correct indication and training in use of NIV equipment is necessary to ensure success and facilitate patient tolerance.
