$200 pulse oximeter for monitoring your oxygen saturation

Question - will the reading of the pulse oximeter discriminate against
carbon monoxide?

In other words, does the use of a pulse oximeter reduce the need of a carbon
monoxide detector? If carbon monoxide replaces oxygen, then the % of oxygen
would decrease and the oximeter would drop substantially when carbon
monoxide is present? Right?

I've never seen anything discussing the issue at all, so I'm guessing it
doesn't (not so much an issue for my ASH 26 E). Jim Skydell had an
article in Soaring about oximeters earlier, so you might check with him.
He's much more knowledgeable about them than I am.
