What happens if a syringe filled with air is pushed inside a human's body?

Nothing. Its a common misconception that a air bubble can kill you. It depends on how much air you pump in. A 2 ml or a 5 ml syringe cannot kill anyone.

I heard of "Z tract" technique, where you use your hand, or finger, to pull the skin and muscle while you inject a deep Intramuscular injection and let it go when you pull out the needle. This is because sometimes when you do a deep injection, the medicine "seeps" back up and out of your skin a little where the needle went in. Z technique blocks the medicine from doing this if it is irritating to the skin layers.

The individual who is responsible for inserting the needle could be pricked by the needle and become infected and criminals are still people.  It is only moral to do this for them.

It is a possibility yes, I am 35 years old, and have been a nurse for 11 years. You are at risk of many different infections/ skin infections. If your skin was peirced, you are at risk for : Hepititis, Tetnus, lead posoning, any bacterial/viral skin infections, and maybe HIV. However HIV does not die when it reaches air, especially if your blood is exposed to the virus. You really need to report this person, and get a throrough exam from a Doctor. Yu may need a Tetnus shot if you havnt had one within 5 years. Even if there is no blood. Your skin has been broken, and contamination may be in the tissue.

call the doctor and make sure he/she does not get dehydrated. push fluids.

There is more pain in imagining it over and over again.  Stop it.  That is why I always press my phobic patients to get some work done right away.  So they keep their imagination in check.  If you hear that is way in the back of your mouth and the needle is an inch long will it make you feel better?   Just think about squeezing the assistants hand,  the music playing in the background, and the outcome that you can control.

By strangulation: pressure on the hernial contents may compromise blood supply (especially veins, with their low pressure, are sensitive, and venous congestion often results) and cause ischemia, and later necrosis and gangrene, which may become fatal. Most hernias can be pushed back into the abdominal cavity. However, if it cannot be pushed back through the abdominal wall, this can lead to a strangulated loop of intestine. If left untreated, this portion of the intestine dies because of loss of blood supply.\nPlease see the webpages for more details on Hernia.

Dont take the item out of the body, it will cause internal bleeding and possibly cause more damage than needed..

An air embolus will travel to the heart and get stuck. Basically, the heart can't fill back up with blood because it can't get the air out of the chambers.\n\nIt takes about 50-100cc of air to cause a problem.

Generally someone is under anesthesia.  The gas is under pressure before it goes to the patient.  Pneumatic pressure would be important in this.

This is sort of a myth, with some exceptions.  I remember as a kid hearing that a single bubble of air would kill you.  This is simply not the case.  A small bubble in your vein is not harmful.  Now if you send a large bubble of air back to your heart, you create an air embolism.  Air takes up space and in an enclosed area, like a blood vessel it can get lodged and can prevent blood getting past it.  Even then it may not kill you, but it could cause an infarct (lack of blood/O2 supply causing cellular death)

I'd think at zero pressure you'd get dissolved gases coming out of solution in liquids (blood, urine, etc) and tissues, causing a general expansion of body contents.  The head being a relatively unflexible container, you'd have bulging eyes, brain leakage and hemorrhage.  Blood vessels in the lungs, being thin-walled and directly exposed to the vacuum, would rupture and leak.  This all happens while your body remains at normal body temperature, which wouldn't be very long, since you're dead.  Ultimately you'd freeze and the fluids would slowly sublime out of your body.\nEDIT:\nOogs's listed site and another I found (ref.) provide the following:\nGenerally the problems relate more to existing pockets of gas expanding and dissolved gas coming out of solution, rather then liquids boiling\nYou lose consciousness in ~10 sec due to loss of blood oxygen via the lungs\nBlood doesn't boil, vapor pressure of water at body temp is only 47 mm Hg (0.9 psi) which normal blood pressure can contain\nGas in the digestive tract will expand possibly causing pain and shock\nYou might get the bends\nYou don't explode\nYou die in a couple of minutes\nIn rapid decompression, forcefully holding the breath will overexpand the lungs causing ruptures and capillary tearing

Well the obvious is that you will damage something and not feel it.  An overdose can cause a heart attack even in young guys.  Its used by some people to prolong the sexual act by decreasing the guy's sensitivity.

It depends on the medicine being administered, but usually it means clamping off the IV so that fluid isn't flowing and inserting the needle into the IV access port (use alcohol to clean this port first).  Then administer (push) the medicine into the IV at the rate required for that medicine (some are fast, some are slow, etc...).  Then unclamp the IV fluid and let it flow!

The amount of some materials in the sample can be changed by chemical reactions, including those that occur inside cells.  The rate of many chemical reactions is decreased by lowering the temperature.\n\nFor example, blood for "blood gases" is placed on ice, and rushed to the lab.  There, it is injected, from the original syringe, into the testing machine.  One of the analytes is oxygen; the loss or gain of oxygen must be minimised.  Thus, the cells are chilled; WBC use oxygen.  The blood is not decanted from the syringe into a tube, for transport, as it may equilibrate with air.\n\nCooling also reduces changes in pH of the blood, which would otherwise result from metabolism, including that of the RBC.\n\nIn general, it slows the rate of change of the sample, so values from tests reflect what was going on in the patient, at the time it was taken.

That is blood pooling under the skin from the needle puncturing your vein...this too shall pass...your body will re-absorb the blood.

Don't worry, it's not nearly as bad as you think. Although, you will feel a little sting, and they will be using a slightly larger gauge needle than would be used for an injection, it won't be bad at all. Also, you will definitely NOT feel the blood coming out. \n\nIt won't take long at all.\n\n1. They will search for a good vain, either by sight or by gently touching the vain\n2. They will disinfect the injection/withdrawal site with either an alcohol or iodine swab.\n3. They may ask you to make a fist\n4. They will insert the needle and withdraw a couple small vials of blood.\n5. It will be over before you know it, and you will probably be saying to yourself  "was that it?"\n\n\nIf you are still feeling squeamish tomorrow, just don't watch while they are taking the blood.\n\n\n                     YOU'LL BE FINE!!\n\nHopefully, this answer helped a bit!!!
