Sometimes.
The compensatory higher HCT (more "trucks") can cause a more O2 rich blood flow thus a higher reading. COPD of any duration usually causes a lower than within normal limts pulse ox. There are a lot of variables and while a noninvasive method of measuring is great, an arterial blood gas in room air would be the real way to tell what's going on.
