acutecarbonmonoxidepoisoning 朝阳区紧急医疗救援中心 培训部 俗称煤气中毒,指吸入过量CO引起的中毒。 在生产和生活环境中,含碳物质不完全燃烧可产生CO。 CO是无色、无臭和无味气体,比重0.967。 根据测定分析,空气中的CO极微少,常不超过0.01%; 当空气中的CO达0.06%时,1小时便能引起人的中毒;如 果达0.32%,只需...
Carbon monoxide poisoning The deadly effect of carbon monoxide was known as long ago as Greek and Roman times, when the gas was used for executions. In 1857 Claude Bernard postulated that its noxious effect was caused by reversible displacement of oxygen from haemoglobin to form carboxyhaemoglobin...
With mild exposure, the effects may begin to wear off as soon as you inhale fresh air or pure oxygen. It may take up to a day for the carbon monoxide to leave your body completely. You might still feel symptoms until it clears or for up to two weeks after your carbon monoxide poison...
密闭的空调汽车内,热水器安装不当,排烟不良,煤气管道漏泄。 Carbon monoxide/məˈnɑːksaɪd/is a colorless, odorless gas produced byburning fuel(eg, oil, kerosene/ˈkerəsiːn/煤油,coal/koʊl/煤, wood)in a poorly ventilated sett...
Carbon Monoxide (CO)中毒 CO 和 红细胞( RBC) 的血红蛋白( Hb ) 结合。CO + Hb = COHb 正常人 Hb 最重要的作用是携带 氧气 O2 O2 + Hb = O2 Hb CO 中毒过程 可以是急性、慢性、 或者 慢性中毒的背景下急性加重 慢性CO中毒 症状 很难发现,只是偶尔头痛,走路不稳,老人家记忆力下降 。。。 慢...
Carbon monoxide (CO) is a colorless, odorless, tasteless, and nonirritating gas produced by the incomplete combustion of any carbon-containing material. Common sources of human exposure include smoke inhalation in fires; automobile exhaust fumes; faulty or poorly ventilated charcoal, kerosene, or gas...

一氧化碳中毒carbon monoxide poisoning 【概述】 一氧化碳吸入人体进入血液后,迅速与血红蛋白结合形成碳氧血红蛋白,碳氧血红蛋白不仅不能携带氧,而且还影响氧合血红蛋白的解离,使血红蛋白失去携带氧的能力,阻碍氧的释放和传递,导致低氧血症,造成组织缺氧,由于人体中脑...

Carbon monoxide poisoning occurs due to many possible conditions. A leaking combustion chamber in a forced-air furnace could circulate carbon monoxide through your house via the warm air vents in each room. Faulty or blocked combustion appliance vents and chimneys are dangerous. Poorly adjusted gas ...
