Despite the uncalled for aspersions cast upon our esteemed colleagues from the Mid West, I have to agree there are an astounding number of folks that seem to believe that blood is in fact blue. That reaction with air turns it red. I drives me fricken nuts. Or that it is a reaction with light that turns it red. Gaaahhhhhh! I don’t think any of the people I remember believing this were from the mid west though, not that there aren’t nutjobs in the mid west, just that I don’t hang out there so I would not know any of them. ---

You want brilliantly, profoundly, impressively red blood? OD on carbon monoxide sometime. It makes ordinary old fully oxygenated hemoglobin look positively dull. ---

[QUOTE=Qadgop the Mercotan] You want brilliantly, profoundly, impressively red blood? OD on carbon monoxide sometime. It makes ordinary old fully oxygenated hemoglobin look positively dull. [/QUOTE] See QTM you are giving the blue blooders ammunition. Now they will claim that red blood is contaminated with CO, thanks. I know you thought it was funny but you need to think about the harm you do. Remember “First, do no harm.” You are a doctor, many of us know it, and many of us are idiots. Do you really want to promote idiocy? Or do you suggest blood is blue? ---

[QUOTE=askeptic] In the sense that oxygenation turns it a darker red, thanks for doing your part to spread ignorance…WTF is uncomfortable about knowing that oxygenation turns blood a deeper red when arguing with some idiot that claims it is blue? [/QUOTE] Bloody hell. Venous blood (relatively low in oxygen content) is a darker red compared to bright red arterial blood (higher in oxygen content). Of course, vampires have a more pallid complexion during the day as opposed to nighttime, which just goes to show you. ---

Title of the thread is “Thank You”, and perhaps you need to relax a little bit, eh? The Queen of England is not a horseshoe crab and vampires are not real. Also, there was at least one spelling error in the OP that you perhaps should jump all over. ---

[QUOTE=askeptic] In the sense that oxygenation turns it a darker red, thanks for doing your part to spread ignorance… [/QUOTE] Sorry, but oxygen makes blood _brighter red_ dark red blood is venous. To prove that blood is, indeed, red inside the body, watch as blood is drawn into a vacuum tube… red, no blue.
