The high flow nasal cannula (HFNC) is a non-invasive respiratory support
designed to deliver flows between 30–60 L/min. Its attractive potential was
based on its comfort and greater adherence to treatment. Different recent
studies showed results where HFNC is not inferior to treatment with NIV
(non invasive ventilation). In addition, it has been used in a whole range of
clinical scenarios with ARF (acute respiratory failure), such as: CPE (Cardiogenic
Pulmonary Edema), COPD (Chronic Obstructive Pulmonary Disease),
Cardiovascular surgery, thorax surgery, abdomen surgery, lung transplants and
patients with do not intubate order (DNI). Likewise, in procedures such as preoxygenation
before intubation and bronchoscopy.
