Is it harmful to the body if air enters the blood vessels during infusion?

In daily life, infusion is a common medical method for treating physical diseases. It cures physical diseases by administering liquid intravenously. However, it is easy for air to enter the blood vessels during infusion. Generally, a small amount of air entering the body is harmless to the body. The air will be absorbed by the body. If a large amount of air enters, it will cause great harm to the body, so you need to pay attention.

Is it harmful for air to enter the blood vessels during infusion?

Although a small amount of air enters the human body and enters the blood vessels, it will be turned into smaller bubbles by the impact of blood flow in the blood vessels and then absorbed, so it will not endanger life. However, when the amount of bubbles is too much, for example, more than 30ml, the shock and impact of the blood are no longer obvious. Once the bubbles enter the heart and blood vessels, they will cause the formation of air embolism. Everyone knows that blood clots are harmful to the human body because they will block blood vessels. Whichever blood vessel is blocked by the thrombus, the blood supply to the organ controlled by that blood vessel will be reduced, and even life-threatening. The principle of air embolism is the same as that of blood clots. These gases that cannot be absorbed enter the blood and block whatever area it encounters. Of course, it is harmful to the human body and may even endanger life. The same is true for exhausting air when giving an injection in a chair. A small amount of small bubbles is harmless.

For ordinary people, it is not a big deal if a small amount of air enters the blood vessels. However, if the amount of air reaches a certain level, it will form "air embolism", which can actually cause death in severe cases.

According to literature records and studies, it is necessary for about 2ml/kg of air to enter the body to threaten life. According to this standard, a 50kg person would need to be injected with 100ml of air, and the injection must be completed within 1 minute before he would die.

This situation is also unlikely to happen during infusion. During infusion, we will see a small cylinder with some air in the middle that keeps dripping water. It is called Murphy's tube, which is used to prevent air from entering the tube.

Of course, this does not apply to children or people with heart problems, and ordinary people should never try it lightly.
