Input: Three RCTs met our inclusion criteria. The studies enrolled 151 participants with CAP or immunosuppressed patients with pulmonary infiltrates. Overall, we found that non-invasive ventilation can reduce the risk of death in the ICU, odd ratio (OR) 0.28, 95% confidence interval (CI) 0.09 to 0.88; endotracheal intubation, OR 0.26, 95% CI 0.11 to 0.61; complications, OR 0.23, 95% CI 0.08 to 0.70; and shorten ICU length of stay, mean duration (MD) -3.28, 95% CI -5.41 to -1.61. Non-invasive ventilation and standard oxygen supplementation via a Venturi mask were similar when measuring mortality in hospital, OR 0.54, 95% CI 0.11 to 2.68; two-month survival, OR 1.67, 95% CI 0.53 to 5.28; duration of hospital stay, MD -1.00, 95% CI -2.05 to 0.05; and duration of mechanical ventilation, standard MD -0.26, 95% CI -0.66 to 0.14. Some outcomes and complications of non-invasive ventilation were varied according to different participant populations. We also found that some subgroups had a high level of heterogeneity when conducting pooled analyses. Non-invasive ventilation can reduce the risk of death in the ICU, endotracheal intubation, shorten ICU stay and length of intubation. Some outcomes and complications of non-invasive ventilation were varied according to different participant populations. Other than the oxygen therapy, we must mention the importance of standard treatment by physicians. The evidence is weak and we did not include participants with pulmonary tuberculosis and cystic fibrosis. More RCTs are required to answer these clinical questions. However, the review indicates that non-invasive ventilation may be more beneficial than standard oxygen supplementation via a Venturi mask for pneumonia.
Output:

We searched the related literature and included three randomised controlled trials involving 151 adults with pneumonia aged around 60 years. We did not include patients with pulmonary tuberculosis or cystic fibrosis. We found that NIV can reduce the risk of death in the intensive care unit (ICU) and the need for endotracheal intubation, shorten ICU stay and length of intubation. Some outcomes and complications of oxygen therapy depended upon the delivery system and primary diseases. The most common complications of invasive ventilation are ventilator-associated pneumonia. However, we must be aware that oxygen therapy is just one of the treatments for pneumonia and the other standard treatments used by physicians are of equal importance. The evidence is weak and it is limited by the small number of studies and the small number of study participants.
