科普观察丨请把N95口罩让给医护人员

2020-02-02 廖国红 新华网

新型冠状病毒感染的肺炎疫情爆发以来,口罩成为了被抢购的稀缺品,特别是N95口罩,简直成了当前最坚挺的“硬通货”。“出门必须戴口罩,口罩必戴N95”,似乎成为了很多人的共识。1月31日,国家卫生健康委疾控局发布了《新型冠状病毒感染不同风险人群防护指南》和《预防新型冠状病毒感染的肺炎口罩使用指南》。指南针对预防呼吸道传染病最重要的佩戴口罩的措施,提出佩戴的原则、推荐口罩的类型和使用对象、口罩使用后的处

新型冠状病毒感染的肺炎疫情爆发以来,口罩成为了被抢购的稀缺品,特别是N95口罩,简直成了当前最坚挺的“硬通货”。“出门必须戴口罩,口罩必戴N95”,似乎成为了很多人的共识

1月31日,国家卫生健康委疾控局发布了《新型冠状病毒感染不同风险人群防护指南》和《预防新型冠状病毒感染的肺炎口罩使用指南》。指南针对预防呼吸道传染病最重要的佩戴口罩的措施,提出佩戴的原则、推荐口罩的类型和使用对象、口罩使用后的处理原则、儿童佩戴口罩的标准和注意事项等内容,指导公众科学合理佩戴并规范使用口罩,实现有效防护的目的。按照指南,并非所有人所有场合都需要佩戴N95口罩。

口罩作为保护自身、抵御疫情的有效工具之一,在应对疫情期间,不仅应该戴,更应该正确地戴。一般口罩有很多种,不同种类的口罩适用的场景也不一样。我们常说的“N95”,其口罩滤料对非油性颗粒物(如粉尘、酸雾、漆雾、微生物等)的过滤效率达到95%以上,是防护级别较高的口罩类型,一般是在近距离面对患者时所使用的。

多数情况下,普通人是没有必要把N95口罩作为标配的。如指南中所提出,在非疫区空旷且通风场所不需要佩戴口罩;在疫情高发地区空旷且通风场所建议佩戴一次性使用医用口罩;有疑似症状到医院就诊时,需佩戴不含呼气阀的颗粒物防护口罩或医用防护口罩;年龄极小的婴幼儿不能戴口罩,易引起窒息。钟南山院士在接受媒体采访时也提到,普通人日常生活中的防护,不一定非要戴N95口罩,一般的口罩,如外科口罩等是能阻挡大部分带有病毒的飞沫进入呼吸道的,在公共场合也就够用了。

N95口罩却是抗击疫情的一线医护人员必须佩戴的口罩。但是疫情发生以来,多地N95口罩告急,尤其接受新型冠状病毒感染的肺炎患者的定点医院口罩急缺。尽管有政府企业和社会各界的多方努力,医疗物资产能的恢复也需要一个过程。

好钢要用在刀刃上。不少专家呼吁,不如把这么宝贵的资源留下来,给疫区更需要的人。比如一线医护人员,他们是抵御疫情最前沿的战士,给他们安全的防护是夺取抗疫胜利的基本保证。或许我们每少用一片N95口罩,奋战在一线与病人密切接触的医护人员,就会多一片N95口罩,多一份防护和安全。

不去抢购囤积N95口罩,将优质医用物资留给最需要它们的一线医护人员,这也许是你我作为一个有社会责任感的平凡普通人,能为抵御疫情所能作出的微不足道但却十分重要的贡献。

不看这篇文章,你的口罩就白戴了!

自从入冬以来,雾霾一波接着一波袭来,这让口罩成为了生活必需品,那大家真的选对、戴对了口罩吗?今天我们就来讨论一下这个话题。N95口罩N95口罩到底是个啥?自从有了雾霾天,N95型口罩就成了当红产品。但其实大多数人都不知道N95是什么意思(小编痴呆脸:和82年的拉菲是一个起名道理吗?)。这里的“N” 代表的是Not resistant to oil,也就是说这种口罩对油性颗粒没用,可以用来防护非油性
