Checking oxygen saturation for person with carbon monoxide inhalation, any suggestions?

A doctor has provided 1 answer

Use ABG: The problem with co monoxide poisoning is that the co binds tightly to the hemoglobin and if you use saturation, yes that ligand is occupied and will be saturated so saturation is up in the spectrophotometry method. The actual method which is the blood gas will show how much o2 is bound to the hemoglobin.
