In this case, the air should be evacuated during the administration of the drip, so that the infusion set avoids entering the air and the air does not enter the blood vessels. If there are a few air in the infusion set that enters the blood vessels, the amount is relatively small, and the air can be metabolized through the body’s metabolism, which does not have a great impact on the human body. In general, it will not cause clinical symptoms to the patient. So don’t worry too much about a few air bubbles getting into the blood vessels when you’re on an IV. The body can metabolize the gases inside, such as carbon dioxide and oxygen, into the bloodstream, and then excrete them through the lungs, so that the air disappears.
