Non-invasive positive pressure ventilation for treatment of respiratory failure due to severe acute exacerbations of asthma.

Non-invasive positive pressure ventilation (NPPV) has been shown to be effective in chronic obstructive pulmonary disease patients with acute respiratory failure. However, its role in patients with severe acute asthma is uncertain. The pathophysiologic condition of acute respiratory failure in asthma is in many ways similar to that of acute respiratory failure in COPD. Therefore, there is reason to believe that NPPV could also be successful in patients with severe acute asthma.
