There are plenty of ways of removing blood without exposing it to air. I regularly handle materials which are much more sensitive to oxygen then blood.

Blood is not blue. It's red. When it's oxygenated it's very bright red, and when it's deoxygenated it's a darker shade (maybe almost purpley but certainly not blue). So you heard wrong. Sorry.
