ok this is something that i just made up, and it makes sense, is just like taking a breath
you first fiill your lungs with air (aspirate) than you push it out!
so when you get the needle you take a big breath! and then let it out!
lol it is ok to forget stuff, you know what... when i was giving lovenox shots, i used to get mad at the little bubble (air seal) and be like, why they always leave air in these needles! (lol!!! i used to flick the syringe and take the bubble out!) that happened to my first 2 days giving that med, than i made a comment to a really nice nurse, who first craked a loud laugh, then told me about the air lock!
