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 much air does it take to cause an air embolism?
To produce symptoms, it is estimated that
more than 5 ml/kg of air
has to be introduced into the venous system. However, complications can occur with even 20 ml of air. Sometimes even injection of 1 to 2 ml of air into the CNS can be fatal.

How much air in a vein is fatal?
A pressure gradient of 5 cm H
2
O between air and venous blood across a 14-gauge needle allows entry of air into the venous system at a rate of 100 mL/s. Ingress of

of air at this rate can cause lethal effects.
