The utility of oxygen therapy for treating pneumothorax

Hallifax R, et al. (2022). Pneumothorax. In: Broaeddus CV. (Ed.) Murray & Nadel’s Textbook of Respiratory Medicine, 7th ed.

“Evidence from a small study in 1971 suggests that use of 100% oxygen in patients with spontaneous pneumothorax can increase the rate of absorption fourfold compared to air (on the basis of mean reduction in pneumothorax size of 4.8 and 18 cm 2 /day, respectively). The rationale is that by reducing the partial pressure of nitrogen in the inspired gas, and thus in pleural capillaries, the rate of nitrogen absorption from the pneumothorax is increased, thereby increasing the rate of resolution of the pneumothorax.” (p. 1545)
