Alterations of blood gas levels and lactic acid in arterial blood gases. (A) pH, (B) PaO2, (C) PaCO2, (D) PaO2/FiO2, and (E) lactic acid. *P<0.05 vs. sham group; #P<0.05 vs. THS group. The data are presented as the mean ± standard deviation (n=10). Pa, partial pressure; FiO2, fraction of inspired oxygen; THS, blunt chest trauma with hemorrhagic shock; PHC, penehyclidine hydrochloride.
