[edit] Blue blood?
Blood in normal individuals is always a shade of red, light for oxygenated blood and dark for deoxygenated. The blue color of veins and tissues in cyanosis is due to the light-scattering effects of surrounding tissues. The same scattering effect also causes the blue color of the sky and large bodies of water. Blue is more lightly to be scattered while red absorbed. Deoxygenated blood is prone to this due to its dark color (less red penetrates the tissue). I have edited the article to reflect this fact, where it previously seemed to say that deoxygenated blood was blue. Xiphoris (talk) 08:57, 7 February 2008 (UTC)
I don't have a formal reference for saying that cyanosis is a sign of choking or asphyxiation, but every AMA reference card or bookshelf medical guide I've seen has referred to that. I'll see if I can track down one of the books, and if anyone else can expand this article or add more references, please do. Jeeves 10:33, 10 Jun 2005 (UTC)
[edit] Poisoning
I'm not a doctor but I heard certain poisonous agents cause cyanosis.. cyanide? CO2? May be someone better qualified could put these in the article. 86.144.47.154 23:55, 6 May 2006 (UTC)
[edit] Solution/Cure
Is there a solution/cure for this skin discoloration problem?
[edit] Blood Colour
Blood is always red, whether that be dark red or a lighter red. How does blood cause this blue effect, known as Cyanosis, if blood is red? I can only presume it is the same reason veins appear blue. Tainted Deity 16:02, 9 August 2007 (UTC)
