Abstract:
Objective To evaluate the effects of applying XF-9801 type of anesthetics waste gas absorber, an activated carbon filter,to removing nitrogen oxides (NOx) and fluoride. Methods Thirty patients, undergoing general anesthesia with enflurane or isoflurane/nitrous oxide, were enrolled in this study.The gas samples were taken at the waste gas outlet of anesthetic machine,to identify the concentrations of nitrogen oxides and fluoride before and after the application of anesthetics waste gas absorber. Results Compared with those before the absorber application, nitrogen oxides and fluroide concentrations in anesthetic waste gas decreased significantly following the absorber application (P
