How Long Does Carbon Monoxide Poisoning Stay Bound To Hemoglobin
Toxic ingestion (also called "poisoning") is a condition in which a person has eaten or drank a substance that causes ill symptoms or damage to his body. Taking an overdose of a medicine, taking any dose of a poison, drinking too much vodka, or accidentally drinking antifreeze . . . are all ...Read more
Depends: The duration of symptoms depends on the concentration of carbon monoxide in the blood stream, the duration of exposure and how quickly you are removed from the carbon monoxide environment. ...Read more
Depends on severity: Mild or moderate symptoms can last from less than an hour to many hours, depending on the severity of the carbon monoxide (co) poisoning, the type of treatment, the victim's other health issues, etc... Studies show the half-life of carboxyhemoglobin (co bound to hemoglobin) to be about 4 hours (3-5 hr) when breathing regular air, and about 1 hour (30-90 minutes) when breathing 100% oxygen. ...Read moreSee 1 more doctor answer
Exposure: Since carbon monoxide binds stronger to the hemoglobin molecule than oxygen, the presence of any level of carbon monoxide in your environment will eventually poison you if you do not remove it (or yourself). Combustion like burning gasoline, or other fuels can create it and if this is in a poorly ventilated area, it will linger and rise to toxic levels. ...Read more
Very little : Co is very toxic and can lead to death quickly. ...Read more
How long does co stay bound to hemogloben - minutes, hours, or days after leaving co contaminated room. ?
Half gone after 4 hr: Carbon monoxide (co) stays tightly bound to hemoglobin, forming carboxyhemoglobin. Because the co doesn't easily come off, the hemoglobin is not freed to pick up oxygen. Studies show carboxyhemoglobin's half-life to be about 4 hours (3-5 hr) in regular air, about 1 hour (30-90 minutes) when breathing 100% oxygen for treatment of co poisoning, and about 15-23 minutes in hyperbaric oxygen (2.5 atm). ...Read moreSee 1 more doctor answer
Depends: Open windows and ventilate well. Fans make it faster. ...Read more
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. ...Read more
Ventilation: Only if there is impaired exhaust of the products of combustion can a room develop co accumulation and the possibility of poisoning. Ventilation should always be to code to prevent this from happening. If you are concerned have a certified hvac technician evaluate you particular circumstance and recommend solutions. ...Read moreSee 1 more doctor answer

It depends: There are exposure limits for carbon monoxide - 35 ppm, but individuals can be effected differently. Look here for more information - http://www.atsdr.cdc.gov/toxfaqs/TF.asp?id=1163&tid=253. The important thing to keep in mind is that effects are temporary. ...Read more
Uncertain: We don't know the effects of low level co poisoning over time. It surprises many people to hear that smokers can have 10-12% of their blood saturated with carbon monoxide or even more in heavy smokers. Since it displaces oxygen from red blood cells, there are probably some long term consequences such as premature aging, but it hasn't been studied in a way that we can be certain. ...Read moreSee 1 more doctor answer
Typically not: While this is possible, proper ventilation and maintenance should prevent carbon monoxide from forming and building up. A home carbon monoxide detector can help make sure you are not in danger. ...Read more
Hard to say: The body is able to tolerate the low level exposures to CO over time with no specific hardship.Any study of its potential effects is hampered by overlapping bad habits of smokers & the inability to isolate cause/effect in a scientific study.It is well known that there are dozens of toxic chemicals released in the smoke, besides the nicotine. Over time the negative consequences of these toxins kill ...Read moreSee 2 more doctor answers
