氧气检测仪氧气浓度多少正常?
氧气,是我们人体呼吸所需要的一种重要气体,但是氧气含量过高过低都会对人体造成不好的影响,因为由于人体无法通过五体感官感受氧气在空气中的含量,因此,尤其是在进入封闭的空间时都需要使用氧气检测仪来检测空间中的氧气浓度。那么氧气检测仪氧气浓度多少正常呢?下面逸云天小编为您介绍:

氧气浓度的数值:
4~6% 40秒内抽搐,呼吸停止,死亡
8~10% 智力丧失,昏厥,无意识,脸色苍白,嘴唇发紫,恶心呕吐
10~12% 呼吸急促,判断力丧失,嘴唇发紫
15~19% 降低工作效率,并可导致头部、肺部和循环系统问题
19.5% 氧气最小允许浓度
20.9% 氧气浓度正常
50% 致命/4~5分钟经治疗可痊愈(密闭环境,如高压氧舱)
100% 致命/6分钟(密闭环境,如高压氧舱或深水)
因此,为了安全:
氧气(02):低于18.5%VOL时气体检测仪报警
仪表上氧气(O2)数值为20.9%VOL,为空气中氧气正常含量。
仪表上氧气(O2)数值低于15%VOL时,人的呼吸就会急促、头痛、眩晕,浑身疲劳无力。动作迟钝,立即离开现场并报集控室。
关于氧气检测仪氧气浓度多少正常这个问题,今天逸云天小编就为大家介绍到这里。氧气检测仪能够在任何场景、任何地方快速的检测出环境中的氧气浓度,在进入封闭空间作业前,我们就需要对空间中的氧气做出检测,无论是缺氧状态还是富氧状态,对我们人体的健康都会带来一定的伤害,严重还会带来生命危险,因此是在进入封闭空间前或在封闭空间内作业的情况下都要对环境中的氧气做相应的检测。
