Why is it that when a person is injected?

Question

with a needle with nothing in it, they die? But when theres something in it they don't die? I don't get it.

Answer 1

To put it simply, if we inject air into an artery, that air will soon reach the brain/heart. Normally causing death as an outcome.

The same cannot be said when injecting air into a muscle, this will only hurt a lot, but not necessarily kill the person.

It is essential to evacuate any gases from a syringe before injecting, for this you simply hold the injection-needle up- and apply a small amount of pressure. Once a small amount of liquid is evacuated, there shouldn't be any gas inside.

Answer 2

if there is nothing in it that means its full of air. Air in your blood is not good you will die air is oxygen if there is a liquid in there liquid can go in your blood and mix which is also liquid.........comprende

Answer 3

Air embolism kills.

Answer 4

Because if there is nothing in it, then that means that it is filled with air.  When you inject air into your veins, you experience a thing called an air embolism.  This will travel through your blood stream and to your heart or lungs causing you to stop breathing, or causing your heart to stop beating.

Answer 5

In most cases of venous air embolism, the air bubbles will be small enough to get stopped at the lungs, but if a large amount of gas is in the veins, that bubble can become lodged in the heart and can cause blood to not be able to get from the right ventricle of the heart to the lungs, and that blood will not be able to become oxygenated, resulting in death or severe oxygen deficiency.

Gas in an artery is called arterial gas embolism, and is much more severe because the air bubble can block blood flow to large areas of the body. This may cause stroke or heart attack.
