Non-invasive ventilation in the management of respiratory failure.

Non-invasive positive pressure ventilation (NIPPV) has been used increasingly to treat various forms of respiratory failure, with benefits in terms of gas exchange improvement, avoidance of endotracheal intubation and a decreased mortality. This review will focus on the recent developments and recommendations in the use of NIPPV in the treatment of acute and chronic respiratory failure, the methodology in the application of NIPPV, and briefly on its proposed mechanism of action.
