There's no air in blood, that's oxygen.

Air consists of more than just oxygen.

"Dry air contains roughly (by volume) 78.09% nitrogen, 20.95% oxygen, 0.93%argon, 0.039% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1%."

If there would be air in your blood, you'd die, it stops the blood circulation.

If you take a needle with only air, or fluid with an air bubble, you can die. That's why they tap the needle before using it in hospitals...
