What is carbon monoxide poisoning?
一氧化碳（CO）是一种无味且无色的气体。它是在燃烧（排气）烟雾中发现的：
- 加热器
- 壁炉s
- 汽车消声器
- 太空加热器
- 木炭烤架
- 汽车发动机
- 便携式发电机
Everyone is exposed to small amounts of carbon monoxide throughout the day. However, inhaling too much of it can cause CO poisoning.
CO can increase to dangerous levels when combustion fumes become trapped in a poorly ventilated or enclosed space (such as a garage). Inhaling these fumes causes CO to build up in your bloodstream, which can lead to severe tissue damage.
CO poisoning is extremely serious and can be life threatening. Call 911 immediately if you or someone you know shows signs of CO poisoning.
The most common symptoms of CO poisoning are:
- 钝头痛
- weakness
- nausea
- 呕吐
- confusion
- 头晕
- 呼吸困难
如果您在CO上大量呼吸，您的身体将开始用CO代替血液中的氧气。发生这种情况时，您可能会失去知觉。在这些情况下可能发生死亡。
You should go to the hospital right away if you’ve been exposed to a source of CO, even if you don’t show symptoms of CO poisoning.
当空气中存在大量CO时，会发生CO中毒。当您在空气中呼吸时，实际中毒会发生，尤其是当您处于通风不佳的地方时。
吸入过多的风险增加如果你’re near any of the following:
- fuel-burning space heater
- gas stove or stovetop
- 热水器
- 壁炉
- idling car or truck in a garage or enclosed space
- 炉
- recreational vehicles with gas heaters
这些设备通常会产生安全数量的CO。但是，如果这些设备用于封闭或通风不良的空间，空气中的CO量可能会迅速增加。
If you use these appliances in your home, you should place a CO detector near these appliances. It’s also important to avoid leaving your car running inside your garage or other enclosed spaces.
A doctor or nurse will take a blood sample to determine the amount of CO in your blood. Once CO levels increase to 70 parts per million (ppm) and above, symptoms become more noticeable. These symptoms may include nausea, dizziness, and unconsciousness.
如果医生怀疑您有CO中毒，一旦您住院后，您将立即获得治疗。快速治疗对于防止威胁生命的并发症至关重要。治疗可能涉及：
氧处理
治疗CO中毒的最佳方法是呼吸纯氧气。这种治疗增加了血液中的氧气水平，并有助于从血液中清除CO。您的医生会在鼻子和嘴上放置氧气面膜，并要求您吸气。如果您无法自行呼吸，您将通过呼吸机收到氧气。
氧气室
您的医生可能会暂时将您置于加压氧气室（也称为高压氧室）。氧气室的压力是正常空气的两倍。这种疗法迅速增加了血液中的氧气水平，通常用于严重的CO中毒病例或治疗孕妇的CO中毒。
紧急护理
您永远不要对自己中毒。如果您认为自己有CO中毒，请立即在户外打电话911。不要开车去医院，因为开车时可能会昏倒。
Even minor cases of CO poisoning can cause serious complications. These may include:
- brain damage
- 心脏损伤
- 器官损坏
- death
Due to the seriousness of these potential complications, it’s important to get help as soon as possible if you believe you have CO poisoning.
为了避免获得CO中毒，您可以采取以下预防措施：
- 确保带有电器或燃烧气体，木材，丙烷或其他燃料的娱乐型汽车的区域有很多通风。
- Buy a CO detector and place it in an area near the source of CO. Make sure to change the batteries regularly.
- 不要入睡或在封闭空间中的空转汽车中坐了很长时间。
- 不要在气体或煤油太空加热器附近睡觉。
- 不要忽略CO中毒的症状。
如果您已经接触过CO，请立即进入户外并致电911。不要回到该地区，直到紧急服务专业人员告诉您可以安全返回。
