If the air bubble is small, it will generally circulate in the veins and reach the lungs where it will get removed in a couple of minutes. The lungs will usually filter out the air so that it can’t travel to the brain or the heart. In addition, the body may also absorb the air itself before it can even get to the lungs.
All in all, small air bubbles are not dangerous to humans, so it’s okay if the syringe has a few air bubbles inside it. However, it is better if there are no air bubbles, as we cannot sometimes gauge the size of the air bubble, and even if it looks small on the syringe, it may be big enough to clog blood vessels.
The subcutaneous injection may not pose threats to the body if there is a small buildup of air bubbles on the syringe used for it. Studies show the air bubbles on subcutaneous injections would only be absorbed by the body from the inside. An air bubble may be dangerous if it is injected directly into the blood vessel, as that is where it will clog the blood flow. This clog is often called a gas embolism.
According to research, an injection to a blood vessel that transfers 100 milliliters of air at 100 milliliters per second can be dangerous to the body. If this amount of air is injected into the artery, it may cause instant death. These problems are the reasons why people should be trained on how to use syringes before testing it on a patient, as an untrained one may perform errors that can lead to severe damages to the body. Fortunately, reports of deaths caused by a gas embolism are rare, and it is all thanks to the knowledge and training that is provided to nurses to prevent medicinal errors from occurring.
How do you prevent air bubbles from appearing inside the syringe?
The key to not getting or removing air bubbles in the syringe is by keeping the tip of the syringe in the medicine so that it won’t come into contact with air. Once you have done the first step, you must then tap the syringe so that the air bubble will rise to the top. Next, you need to push the plunger gently in order to push the bubbles back to the medicine container. If a lot of bubbles appear on the syringe, you would need to empty it and fill it again with the medicine. Don’t forget to do the first three steps while getting medicine inside the syringe again. After you are done using the syringe or if you are going to put it down, remember to put the cover back on its tip so that no air can get inside the tube. Also, make sure that you dispose of the syringe immediately after putting the cover on the tip.
As mentioned before, it is easy to utilize a syringe, but it is difficult to perfect the use of it. It is best that people should not self-medicate and inject themselves with medicine, as most of them may not have enough training to use a syringe. If you are experiencing any aches or pains in your body, you must consult a doctor and see what medicines or procedures he or she can recommend.
