本文就飞行员氧气面罩的污染情况进行了卫生学调查。结果表明，外观清洁和较清洁的占９２．３％；不清洁的占７．７％。检出葡萄球菌、大肠杆菌和链球菌等四类致病菌，揭示了氧气面罩不同部位的致病菌分布特征，按清洁度划分的三组间致病菌阳性检出率无明显差异。建议对氧气面罩应采取科学的消毒措施，制定我军飞行员氧气面罩卫生标准。
This article conducted a hygiene survey on the contamination of pilots’ oxygen masks. The results show that the appearance of clean and cleaner accounted for 92.3%; unclean accounted for 7.7%. Staphylococcus aureus, Escherichia coli and Streptococcus were detected four kinds of pathogens, revealing the different parts of the oxygen mask distribution of pathogenic bacteria, according to the cleanliness of the three groups of pathogenic bacteria positive detection rate was no significant difference. Proposed oxygen mask should take scientific disinfection measures to develop our pilots oxygen mask health standards.
