Objective:
To evaluate the effects of noninvasive positive pressure ventilation (NPPV) on postoperative pulmonary function recovery in patients receiving thoracic surgeries.
Methods:
Fifty thoracic surgical patients were enrolled in this prospective randomized controlled study and divided randomly into conventional treatment group and NPPV group. In the NPPV group, the patients were given NPPV therapy on the basis of conventional treatment. The volume of the residual cavity and the lung function were recorded.
Results:
At one week after the operation, the changes of lung function parameters were similar between NPPV and control group (P>0.05).
Conclusions:
NPPV following thoracic surgeries produces no obvious effects on postoperative pulmonary complications or the lung functions, and bullous resection have less adverse effect than lobectomy on the lung function.

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
