Pure said:Good posting Des. It seems there is agreement around times, dangers, etc, and your medical expertise is welcome.
Just out of curiosity, why do you think something 'tied off' turns dark blue or purple fairly soon.? Surely if it were just a lack of blood, the flesh would look whitish/pale; possibly very light blue.
Best,

PinkOrchid said:I'd like to just add to Desdemiona's excellent explanation. After red blood cells bring oxygen to tissue, they pick up excess carbon dioxide. If the carbon dioxide is not removed from the tissue, it can change the acidity of the environment, which can kill cells just as easily as oxygen deprivation alone.
