different aspiration bubbles

[Dk]

Not sure if its anything, probably isnt.

But it doesnt hurt to ask why haha.

Whenever i aspirate in my quad, its always one big bubble, comes in, goes back out.

now when i do delts it is always a ton of tiny little micro bubbles that rush in then go out.

i know, its nothing most likely, but what difference would it make where im aspirating?

this isnt just a once in awhile thing, these forms of bubbles are aspirated 100% of the time in each said site.

obviously not worried haha, just wonder why

I would say and this is just a theory that it's due to the size of the muscle fibers, the quad obviously having more thicker/longer fibers would make a larger bubble and the shoulder have small muscle fibers due to the overall size of the muscle would have more smaller bubbles.. that's just my theory, in the end it does not matter, as long as you are not pulling out blood your good to inject.

^ this makes sense. our bodies are not in a state of vacuum. they do contain air space, and Canadianmuscle0803 has a good theory

Haha don't worry about it.It just the pressure inside the needle as soon as you let go the the air is gone,plus the muscle can absord some air,plus you would have to put a large volume of air in the vein.I always have some small air bubbles.

Its next to impossible to keep it air free . you would need 3cc of air to do damage .
next time you see someon in the hospital that is on an IV drip , just look at all the air that goes into the vein . the line always has air spots . the nurses try to keep as much out as possible , but you need a large amount to do damage.

but I think canadianmuscle's theory makes sens

The air is not an issue at all. It diffuses out if introduced outside of the blood vessels.

The reason for aspiration, and the only concern (besides injecting 3cc of air into a vessel) is to make sure you're not injecting into a vein/artery and potentially passing out due to the sudden acidosis of the blood.

i noticed the exact same thing when i aspirate.

[Amoral]

I've always been taught it was the pressure difference between the inside of the body and the inside of the syringe. When you introduce pressure/temperature differences to a substance, you can induce formation of bubbles.

Although sometimes I get the larger bubble up the needle, ie. quad shots, and then sometimes I get like 100 tiny ass bubbles that appear out of nowhere and disappear when the plunger is released, ie. bi shots.

I'm almost thinking it has to do with different parts of your body having different relative pressures compared to outside the body, but this might possibly go hand in hand with what canadianmuscle0803 is saying. The smaller the fibre, the more of a vacuum the muscle creates...
