Why is there an air buble in the injection Lovenox?

More to the point, to allow complete injection of the drug- When giving injections intraperatoneally or intramuscularly(in the gut or butt) we take a tiny bit of air into the syringe so that there isnt any drug left over-to make sure you have your full dose.  This isnt done in IV injection because of the (low) risk of air embolism blocking a vessel.\nBut, the first answerer was correct as well, and they got here first...

It means you have an air leak in your emission system. No big deal, quite often a gas cap not sufficiently tightened. That will give you some idea of the problem.

They're right, it's air pressure...but more specifically, the air pressure outside the plane is lower, so to keep the pressure outside from crushing the plane while it's in the air, they have to pump air inside the plane from the inside.\nThink of a balloon underwater.  If you blow up a balloon under water, it is considerably more difficult to do so underwater than in the air, because the water's pressure is greater than that of air.\nSo, the reason why people's ears get "stuffed" is because the plane's inside is being pumped with air from the inside to prevent the plane from compressing.

that first answer was great and hilarious :) does that guy even read the questions he answers?\n\nanyway, what this could be is either popping from your acetabulofemoral joint, your sacroiliac joint or your lumbar joint...\n\nor it could be any of the internal organs emitting a strange sound...\n\nit would be wise at this time to get an xray of your lower abdomen/pelvic area and see if all the structures are aligned and balanced... good luck

blackpowder or gunpowder exploding makes the cracle sound. they just put it in smaller sections so it wont be as loud

I have no idea what you are talking about. Can you add some clarification please?\n\nAh...okay, it is called a "vapor trail" and it is left by aeroplanes as the air condenses behind the earoplane engines and wing tips. It is simply water vapour, the same as clouds are made of.

This is usually because you're also swallowing a large amount of air that has become trapped under the descending liquid. You may notice that you belch shortly after this happens.

its irritated adenoids. I suffer from allergies and will sometimes make the same noise . LOL scared my hubby on our wedding night , It is a way to try to alleviate the itchy feeling .

Its when theres an air pocket and we rub it and we push that air pocket...so it makes a farting noise.\n\nIt happened to my ex a few times long time ago, but I knew it was normal so it didnt phase me.\n\nAll men know its a normal thing, so dont wig out...its a beautiful thang.

you may have a bad coolant temperature sensor.  This causing a massive negative temp reading in pcm and runs the veh super rich.  also way it chuggs and farts while you get it to smooth out!

Yup...it is perfectly normal...albeit kinda embarrasing.  All it is is air that gets compressed during intercourse escaping from the vagina....

Air is blown across reeds.  Kind of like a backward clarinet, which may account for the ... unique... sound.

It's a gasket - prevention of leaks.  Look into the Challenger explosion.  They had an issue with faulty O-rings.

Your vocal cords are designed to vibrate in a mixture of Nitrogen and Oxygen (air) and when you replace that with lower density Helium the vibrations come out at a higher pitch and make your voice sound funny.

I think it's because they run Nitrous Oxide. Nitrous Oxide is also called laughing gas.

Do you mean you were having sex and a farting sound came out of your vagina? Hun, that's normal.  A guy pumping his penis in your vagina repeatedly is going to trap air in there, if you suddenly change position or your muscles clench or he suddenly thrusts is deeply then the air is going to be randomly pushed out causing the sound of fastly escaping air which sounds like a fart.  Just recognise that a 'vart' is normal and that it's going to happen everyso often, just laugh a bit and carry on.  If your guy has any sense or maturity about him then he knows what's going on and will just be waiting for you to stop laughing so he can get back to what you two were doing before hand.  Guy's don't care, why should they?  It's not like you dutch ovened him.  Forget about it, relax any clenched muscles and get back to the good lovin' :D enjoy
