The question I have is related to the fact that when a large amount of Carboxyhemaglobin is present we flood the patient with 100% O2 to remove the carbon. It is my understanding that flooding a patient with 100% O2 is useless in the presence of a large amount of Methemaglobin, because of the fact the hemaglobin is reduced and oxidized so it can not pick up the O2 anyway. Is this the truth? Or should we continue to give these patients 100% O2.
