A member asked:

Please explain if it is possible to use a pulse oximetry to check oxygent saturation for someone who inhaled carbon monoxide?

A doctor has provided 1 answer

Not infection: Using pulse oximetry will not show a real oxygen saturation of the hemoglobin. Co binds to hemoglobin more avidly than oxygen, shifts the saturation curve to the left as what is measured is occupied hemoglobin (reduced) even if the co is the one occupying it. It is best to use the abg.
