目的了解高压氧舱内感染管理及其危险因素。方法通过现场查看和相关资料分析的方法,对医院高压氧舱中存在的医院感染危险因素进行分析并制定防控措施。结果环境密闭、空间狭窄、空气不流通、危重患者多及一次性吸排氧用具使用不规范等,是高压氧舱内医院感染危险因素。结论高压氧舱内存在呼吸道感染的危险因素,需采取有效的防控措施。 Objective To understand the management of hyperbaric oxygen capsule infection and its risk factors. Methods The hospital risk factors of nosocomial infection in the hyperbaric oxygen chamber were analyzed and the prevention and control measures were established through on-site inspection and related data analysis methods. The results of airtight environment, space is narrow, the air is not circulated, the number of critically ill patients and disposable oxygen using non-standard utensils, etc., is a hyperintense nosocomial infection risk factors. Conclusion There are risk factors of respiratory tract infection in hyperbaric chamber, and effective prevention and control measures should be taken.
