I'm not sure if it would be able to register from a few seconds of smoke passing over it, the way that a smoke detector probably would. Maybe ... who knows? Someone should try putting a detector in a closed garage with a running car and see how long it takes to go off.
or get a big bag put the detector in there and blow it full of smoke.
also i dont think your body would take a huge amount of CO in (remember your breath in about 18% oxygen and exhale about 17-17.5% oxygen)
