Talk:Methaemoglobin
From Wikipedia, the free encyclopedia
Problem with this article:
"Metheomglobin is unable to carry oxygen" not true. the problem is that the oxygen affinity is so much higher that is is unable to *release* the oxygen it is carrying.

In case anyone was wondering, I decided to merge the methemoglobin article into this one, because this was more substantive and had a longer edit history. The request to merge had been sitting there for quite a while without any responses on either talk page, and the two articles were on the exact same protein (with only a spelling difference). --Leapfrog314 02:18, 30 March 2006 (UTC)
Other causes of Methaemoglobin are the fumes from carbon arcs (like those used in motion pictures) as nitrous oxide produced is oxidized to nitrogen dioxide by atmospheric oxygen.
Silver Nitrate used in dressing burn wounds can be another cause.
Effects:
10-20% mild cyanosis 20-40% visible cyanosis, dyspnea(difficult breathing) with activity 40-60% cardiopulmonary problems, severe cyanosis >60% ataxia and death
Treatment: ascorbic acid, methylene blue

[edit] protein vs disorder
Hi. If anyone's reading this... it looks to me like a lot of this material, such as most of the "causes" section, belongs on the methemoglobinemia page rather than this one. But I don't know enough biochemistry to feel confident changing it. 66.45.137.204 15:41, 25 March 2007 (UTC)
