A study evaluated the effectiveness of noninvasive ventilation (NIV) in 72 postoperative patients experiencing acute respiratory failure (ARF).
Out of these patients, 58% successfully avoided intubation after using NIV, and factors like decreased oxygen levels and higher illness severity scores were linked to NIV failure.
The findings suggest that while NIV can be beneficial for postoperative ARF patients, the presence of nosocomial pneumonia is a key predictor of its failure.
