1. How far do you pull the plunger back?
2. If there is no blood then what is pulled into the syringe, is it air?
3. If there is blood then you pull it out and start again. Is it ok to re inject again with the same syringe and blood mixed gear?

1. pull the plunger back as far as it takes to see the air buble come into the syringe. i know some guys that just pull it back till u can see it in the needle (the lil plastic part) i pull it back until its into the syringe itself. there will be quite a bit of resistance on the plunger when u pull it back, also make sure you dont move around to much itll hurt like hell the next dayOriginally Posted by king6
2. yes its air bubble
3. i would change the needle if you restart and maybe alcohol the spot again as well. but im very cautious
Is it safe then to re inject that air bubble into you?Originally Posted by Haro3
when u switch needles flick the syringe itll bring air bublles to the top then jus push the air out. the blood wont hurt u but if you can avoid it u dont want to inject a big air bubble.Originally Posted by king6
but if you mean after you have pulled back and the bubble comes into the syringe yes you can inject that. you'll see what i mean, when u pull back there will be a resistance and if you let the plunger go it will suck itself right back down. youll find out when u actually do it.
yes, it came out of you...it'll go back in w/o any danger.
it takes about 10ml of air injected to kill you, I think....maybe less but its more than most people think
your not injecting in a vein so a small bubble wont hurt you
you'll know if u hit a vein,i did yesterday for the first time when u aspirate there will be no resistance and blood will come very quick,just change pins pick a diff spot and proceed as usual,it's very uncommon i believe to hit a vein
Cool, thanks for the info gents.
This has happened to me several times as well, you really do not need to pull THAT HARD on the syringe. If you have hit the vein, you'll be able to tell quite easily, as the blood rushes in quite fast. Just an easy pull-back is enough, and as they mentioned above, try NOT to move much.Originally Posted by reppedout1
So if you hit a vein, you wont need to asparated to know, the blood will just enter the needle as is?Originally Posted by Terinox
The point of aspirating is to make sure you have not hit a vein. Its really easy, just take it nice and slow. Make sure you take your time injecting as well (about a minute per CC).Originally Posted by king6
No, I said that you don't have to pull that hard. A light pull-back is enough, because IF you were in a vein, it does not take that much force to get the blood into the syringe.Originally Posted by king6
Ok, and then just inject real slowly to avoid getting the lump.Originally Posted by Terinox
no you have to aspirate as normal,just as sonn as you see blood you'll know u hit a vein,i aspirated and blood immediately shot into the barrel as soon as i pulled back
I use to make sure I had an air bubble in the syringe when i asparated, you dont have to force that hard. Like everyone said, when your in a vein just the slightest pull will make the blood go into the syringe. Take a pin and try to asparate in a glass of water with one hand, youll see it doesnt take much to get none oil based stuff in the pin. Throw out the pin after, dont reuse it![]()
Here is some info for you dudes with regards to air in the syringe and what it actually take to kill you. Now this is into a vein.
SCIENCE IN CRIME DETECTION
DEATH BY AIR INJECTION
Dr. Anil Aggrawal
Technically known as cases of "air embolism". The word embolism comes from Greek en, "in," and ballein, "to throw or cast". Henceforth we will be using the term "air embolism".
Before telling anything further about death by air embolism, let us first understand a little bit about the way our blood circulates in our body. This is very essential to understand how a person is killed by injection of air. Our heart is comprised of 4 chambers. There are two chambers on the right and two on the left side. The chambers on the right side are known as right atrium and right ventricle, while the chambers on the left side are known as left atrium and left ventricle. Bad blood (deoxygenated) from legs, head, arms and in fact from every part of the body returns to the upper right chamber called the right atrium.
With each contraction of the heart the right atrium sends this bad blood to the right ventricle. The right ventricle, in turn, sends this blood to the lungs via pulmonary arteries. Do not let the complicated names baffle you. Just remember that atrium and ventricles are fancy sounding names of some chambers of the heart. Ventricle is a larger chamber than atrium. Also keep in mind that "artery" is the name of a conduit which takes the blood away from the heart while vein is the name of a conduit which brings blood to the heart. The word pulmonary comes from Latin pulmo, "the lung". Thus "pulmonary artery" refers to a conduit which takes the blood away from the heart towards the lung.
In the lung, the bad blood is purified (oxygenated). This is done by the help of the air which we breathe all the time. The pure blood is returned to the heart via pulmonary veins. The blood comes in the third chamber of the heart known as left atrium. Left atrium sends this blood to the left ventricle, which in turn, pumps this pure blood to the whole body via a very big conduit known as the aorta. The body organs use this pure blood, and when this blood becomes impure, it is once again returned to the right atrium. And thus the circulation goes on.
Now we are ready to understand how air embolism works. First of all we must appreciate that nature has made this whole system of circulation air-proof. This means that there is no way, air could enter this system of conduits and pipes. If somehow air could enter the system (such as by injection of plain air through a syringe), the air will form an "air lock" within the system. This "air lock" is quite familiar to plumbers and owners of diesel engines, where the normal flow of liquid through tubes is wholly or partially blocked by air. Quite in the same manner this air lock blocks the flow of blood through the arteries and veins, thus bringing the circulation to a halt. Let us make this a little more clear.
Air could be made to enter the circulation either through the arteries or through the veins. When an injection of air is given, the air bubbles start travelling towards the right atrium. From right atrium they keep travelling onwards till they come to the lung. Here the capillaries are too narrow to allow the big bubbles to pass. The result is that these bubbles get entangled in the blood vessels of the lung. The whole blood traffic stops and the person dies very quickly. In fact this bad blood can not be purified by the lungs, because the traffic of blood towards the lungs has been stopped. The body can not imagine that such a sinister thing has happened. It "thinks" that the blood is not getting purified because of lack of air. So it quickens the respiration. The person starts gasping. But nothing helps because the cause lies somewhere else and the person dies.
Now this is where discrepancies lie…in how much is needed. This article cited 200 mL (cc’s), which I think is an exaggeration. Other articles I have come across state wide ranges…anything from 20 mL to the above mentioned 200. I say about 20 mL, as an educated guess…and I read that in some nursing journal during schooling as well. 20 mL is approximately the length of an IV line…so those who’ve been in hospital can now envision how much is needed.
I have never been able to pull hard enough to get air into the syringe when I am all twisted around like a gumby.
The one time I got blood when when I pulled up with my index finger (like I always do) and viola, there was blood.
