How much carbon monoxide is lethal?

50% This varies, but 50% would be lethal for most people. However, small children, an unborn child, and elderly would be more susceptible to lower doses. Carbon monoxide binds to blood cells causing caboxyhemoglobin which makes the red cell unable to oxygenate. At 10 to 15 % most people will be symptomatic- headache, fatigue, flu like symptoms. As the perecentage increases so do the symptoms.

Help please? How much time does it take for carbon monoxide to affect you?

Instantaneous. Carbon monoxide does damage by binding to red blood cells, causing them to not be able to carry oxygen. It happens as soon as the CO contacts the blood and it will stay attached to the hemoglobin in the blood for many hours. It is reversed much faster when the person is treated by breathing 100% oxygen. It's normal to have a little CO in the blood - smokers have up to 15% (40% is lethal) Read more...

When is carbon monoxide formed?

Incomplete combustio. Generally, it's formed from incomplete combustion of fossil fuels. In chemistry, a hydrocarbon should burn in oxygen to carbon dioxide and water. However, other by-products may form such as carbon monoxide, nitrogen, and sulfur containing compounds. Carbon monoxide is dangerous because it preferentially and more tightly binds to hemoglobin molecules than oxygen. Cells can't use co so they die. Read more...

Does carbon monoxide accumulate in the body?

CO2. Once removed from the carbon monoxide containing environment, there will be a gradual release of the gas over time. It will only accumulate if you remain in the contaminated environment. Read more...

Is there a possible way to detect carbon monoxide?

CO Detector. Carbon monoxide (co) is colorless, odorless, and lethal in adequate concentrations. It requires a specific detector, most of which are independent from a traditional "smoke detector, " but some brands are combination units. They are strongly encouraged for sleeping areas. Read more...

How long till you are affected by carbon monoxide?

Depends on Concentra. Tion. Symptoms and signs of carbon monoxide poisoning depend on the concentration of the gas in inhaled air and length of exposure. At a concentration of 4000 parts per million, it is lethal in 30 minutes. Read more...

How long could carbon monoxide last in the system?

Depends on amount, But, roughly one week if breathing room air, about 6-10 hours if breathing 100% oxygen, and even shorter if provided hyperbaric oxygen treatment (which is 100% oxygen at 2-3 times usual atmospheric pressure). Read more...

Is the damage caused by carbon monoxide reversible?

Yes. For the vast majority of carbon monoxide exposures the symptoms are reversible. However, for people who have significant altered mental status the likelyhood of some type of permanent damage is higher. Read more...
