ABSTRACT
Objective: To supply the quality of hospital centers, conduct research and analysis, develop appropriate purification scheme. Methods: According to the specific hospital ward equipment used and production center with the use of state gas sampling filter device;through the device each ward of the hospital wards with a central gas sampling equipment, comparison and analysis. Results:through the filter sampling, analysis of equipment with a gas composition of trace impurities, impurities resulting inferred parts, the first time to get in touch with the manufacturers to jointly negotiate improvement programs. Conclusion:Hospital Center survey analysis is a gas quality monitoring and promotion of the development, the need to promote open each hospital to develop a central supply more complete safety indicators. Such a center gas quality testing program can be more effective in protecting the quality of gas supply, more conducive to clinical treatment and use.
