carbon monoxide affinity
When I was in first aid class, they said it was about 200 times stronger
affinity than oxygen. Sometimes they use "hyerbaric" oxygen chambers to treat monoxide poisoning. High pressure tanks, where the patient is in higher pressure. Like they do for divers who have "the bends". -- Christopher A. Young Jesus: The Reason for the Season www.lds.org www.mormons.com "(Pete Cresswell)" wrote in message ... RE/ At 800 ppm, for instance, the symptoms will start in 45 minutes and you'll be dead after 3 hours. At 1600 pps it starts in 20 minutes and you're dead 40 minutes after that. At 6400 the pain starts in 2 minutes and you fall down go boom die in 10-15. This is why I've got CO monitors - plural - in my house. This stuff is NOTHING to fool around with. And, according to what I've heard, a nasty little add-on is that one's hemogloben has a greater affinity for CO than it does for O2. Net result is that once the stuff's bonded to enough hemogloben even if you get out to fresh air or somebody drags you out you're still going to die because the O2 from the fresh air can't get to the hemogloben. -- PeteCresswell |

So yes haemoglobin does have a higher affinity for CO than O2. BUT once you are in fresh air there is no CO in the air for practical purposes so you start to lose CO from your blood immediately. This leads to the odd situation that if you call a hyperbaric unit and tell them the CO level in a victims blood they ask how long to reach them and the level. If you are close they will take someone with a lower level than if you live further away. Why?because they know that in the time taken to make the journey the level will fall by a predictable amount. Treatment with oxygen at the scene helps but the first big step is get them into fresh air, I have seen the plots of CO levels , it does work. N |

The advantage with the hyperbaric chamber is that some oxy dissolves in the
water in the person's blood. And that helps oxygenate the cells. -- Christopher A. Young Jesus: The Reason for the Season www.lds.org www.mormons.com "Not Me" wrote in message ...
