What happens if you get an air injection?

I believe that for many friends, both infusion and injection are familiar to them. Every time an injection or infusion is given, there are special medical staff to perform the operation. However, many friends are not familiar with the term air needle. So what is an air needle? As the name suggests, it means injecting air into the body. The peripheral blood vessels of the human body are divided into veins and arteries. So what will happen if an air injection is given? The following is a detailed introduction for you. I hope friends can patiently read the following content.

The principle of death caused by air injection is to form air embolism in the air, blocking blood circulation.

1. What is the process of air injection?

First of all, the prerequisite for an air injection is that one has to have the intention to kill someone like the paramedics in the case. Secondly, a sufficient amount of air is injected into the vein, and the components in it will first combine with the hemoglobin in the blood. Those that cannot combine will return to the heart and then enter the lungs and be discharged with the alveoli. If it is still not completely discharged, the remaining air in the heart will be mixed with the blood to produce a large number of blood bubbles.

2. How do air injections cause death?

On the one hand, the heart can only pump out very little blood, which can lead to acute heart failure and organ ischemia. On the other hand, the small bubbles that are ejected can enter the pulmonary artery or the cerebral artery, causing pulmonary infarction or cerebral infarction. A tiny embolism on any branch of a blood vessel can cause angina pectoris or even myocardial infarction.

3. Is it really that easy to give an air injection?

From an operational point of view, directly injecting a large amount of air into a vein requires the cooperation of the victim and a certain amount of medical practice experience. Directly injecting air into an artery that can kill a person requires more medical experience and a greater risk of being exposed. Therefore, the probability of this trick appearing in reality is much lower than in film and television dramas. The reason why the Italian paramedic in this case was successful was that each of his targets was a seriously ill patient, so it was easier to do so. Therefore, I appeal to everyone here not to have the intention to harm others.

Air injection was also a form of rescue

Given that air injections are known to be lethal, it is astonishing that injecting air into the human body was once considered an effective treatment for a long time.

This happened in the 1980s and 1990s. The method was to inject 10-15 ml of sterilized air into the patient's muscle and waist pain to relieve or cure the pain. Some people also reported in literature from various places that the cure rate reached 98%. Xiaoquan can only say that this dangerous behavior is simply risky and outrageous.

However, friends, don’t worry too much. Although this seems ridiculous, in fact, a small amount of air entering the human muscle tissue is actually harmless.

Will air get into our daily infusions and injections?

Speaking of the fact that air can be fatal when it enters the human body, you may worry that when we are sick and go to the hospital for infusions or injections, will there be a danger of air entering our blood vessels? There is no need to worry about this, as this kind of thing does not exist. There is negative pressure in the infusion bottle, and the air is lower than the human blood pressure, so air cannot enter.

Since infusion will not allow air to enter the human body, what about injections? You may have noticed that before each injection, the most important step for the nurse is to empty all the air in the syringe.
