The O2 has to get to your lungs, which exchanges CO2 with O2 in the tiny blood vessels in your lungs. If your airway is blocked up-less O2 can get to your lungs. Also, the cold may affect the way your body reacts to the O2. O2 is also used topically with wound care-so your idea about the O2 going directly through the blood vessels in your nose may not be too far off.
