I doubt about oxygen being needed for Fire Release jutsus, this is a series where people actually breath out fire, make water out of nowhere, produce lightning out of their body and many more. So I doubt about Chakra needing Oxygen to become fire. well the elemental natures of chakra are not the real deal, a shinobi shooting out a giant fireball isn't shooting out a real fire its simply chakra that has the properties and appearance of fire

Pretty much confirmed by the fire release page
