In brief: Yes

Carbon monoxide (co) stays tightly bound to hemoglobin, forming carboxyhemoglobin.
Co comes off the hemoglobin gradually as the hours go by. Studies show carboxyhemoglobin's half-life to be about 4 hours (3-5 hr) in regular air, but about 1 hour (30-90 minutes) when breathing 100% oxygen for treatment of co poisoning. Increased oxygen makes the co come off the hemoglobin and leave the body sooner.

In brief: Yes

Particularly high flow oxygen (delivered by a face mask) as this will decrease the half-life (time carbon monoxide stays in the system) dramatically.
