What happens if there is air in an IV line?

When an air bubble enters a vein, it’s called a venous air embolism. When an air bubble enters an artery, it’s called an arterial air embolism. These air bubbles can travel to your brain, heart, or lungs and cause a heart attack, stroke, or respiratory failure. Air embolisms are rather rare.

How do you avoid air in IV tubing?
