Embolisms refer to a blockage in the blood vessels. With an air embolism, the blockage in the blood vessel is air. Air embolisms can affect the arteries or veins, but embolisms of the artery are more severe because they are more likely to reach the brain, causing a stroke. If the air embolism travels to the lungs, the lungs can fail. A heart attack can occur if the air embolism reaches the heart.
