1. What is carboxyhemoglobin? When and why would we be concerned with this level?
1.Carboxyhemoglobin is when carbon monoxide is rapidly absorbed into the blood it binds to hemoglobin to form carboxyhemoglobin in the red cells (cherry red appearance).
An abnormal form of hemoglobin. This reduced heme is combined with carbon monoxide instead of oxygen. The bond carbon monoxide makes is 210 times stronger and therefore carbon monoxide tends to displace oxygen in hemoglobin and remains attached to hemoglobin.
A carboxyhemoglobin concentration higher than 3% in nonsmokers and higher than 10% in smokers indicates some degree of carbon monoxide poisoning .
The treatment for carbon monoxide poisoning is :-
Breathing in 100% oxygen at more than 1.4 atmospheres within a hyperbaric chamber.
