Kao, H.K., Wang, J.H., Sung, C.S. et al. (2005). Pneumothorax and Mortality in the Mechanically Ventilated SARS Patients: A Prospective Clinical Study. Critical Care. 9(4):R440-5.
The authors conducted this study to determine the effects of mechanical ventilation on pneumothorax and if pneumothorax in SARS patients increased mortality. They did not find any increase in mortality from pneumothorax. They found that patients who developed pneumothorax presented with significant respiratory involvement upon admission, and that these individuals required "meticulous" respiratory therapy and monitoring.
