Ask a Doctor and Get an Answer to Your Medical Question ASAP
Hi there. Thank you for your question. I will be helping you out with your queries
A small amount of air is nothing to worry about.
It requires at least 40-50 ml of air to potentially cause any issues
she did do it a few times is this a concern
So no worries.
No it is not a concern.
That would still be a very small amount of air.
is a blood test bottle no were near 50ml
A blood test bottle is usually around 5 ml
oh right ok so evan tho blood was not coming out in the bottle would air actualy of ben in the bottle
Did not get your question.
Can you please explain your last question.
would air of actualy been in the bottle when she pulled the syringe the first time
When there is an empty space there would be air.
and is this normal what she did? do the do it a lot if they cant get blood first time keep pulling the syringe back up and down?
That is something very common.
Done almost daily.
They do keep pulling the syringe up and down until they hit the vein
so basically a blood sample cant cause air in vein evan when pushing syringe back in and out a lot of times im just really worried I suffer with anxiety so worry alot
That is right
I think she was in a vein already cause she found it just wasn't giving any blood or if no blood comes out does that mean its not a vein
If no blood comes out it means she was not in the vein.
she said she was in a vein just no bloo coming out
Blood will always come out if a vein is hit properly.
So she either missed the vein or hit it and then the needle move.d
okay thank you she did try a few timesin both arms my veins had disappeared cause was cold
You are most welcomeWish you all the best.I would appreciate it if you rate me by clicking on one of the smilies below.Kindest regards

I am here to answer your concerns.
You can ask any number of questions until you are satisfied.
thank you just a worried person
Most welcome. I understand you are worried and I am here to help you in anyway else that I can.
This session is open for any further questions.
Rate me only when you are done asking your questions.
if air would of caused a problem would this of happened already got me blood done around 9 lastnight
Yes it would have happened already.
Air in the blood vessels causes what is called as air embolism
And this happens instantly.
So if this were to cause any problems you would have experienced the symptoms arleady.
what are the symptoms
are you really ill with them
Shortness of breath, chest pain, increased heart rate, palpitations.
You become severely ill actually.
so with it been lastnight something would of happened by now
Yes, something would have definitely happened already
so if she was in a vein and air went in when he pulled it loads of times that's fine caue only a small amount would of gone in?
and is this something they have to do to patients if no blood comes out do they keep trying and trying like that? or are they supoosed to stop once If no blood comes out?
Well, usually they would go in and out at least two or three times when they do not hit a vein.
While taking blood out a negative pressure is applied like a vacuum which is why the chances of air going into the veins is very low indeed.
she didn't take the needle in and out she was pulling the vaccum syringe in and out
The vacuum syringe would almost never cause air to be pushed into the vein because of the negative pressure in it.
So the chances of even a small amount of air going in is very low indeed.
Are you with me?
yes so basically no air would or probably went in
she put the needle in then pulled the syringe so pull the blood out and as none come out she pulled it up again still none come out so she pulled it again
Most likely no air went in
I di say to her are you allowed to do tha and she said yes
but I thought as you pulled the syringe well air filled the syringe if no blood did so if she then pushes it back in to my vein what about the air or would air not of gone in
If she pulled the syringe completely out then the vacuum or the negative pressure in the bottle is lost.
what do you mean
the needle was still in my arm she didn't pull the needle out just pulled the syringe
pulled the syringe back no blood come out so she pushed it back up to then pull again so blood come out
If the blood came out it means that the negative pressure was still there in the syringe
So it is not possible for air to go into the veins when there is negative pressure in the syringe
no blood come out this is what I am saying
But it did come out the second time around.
she pulled the syringe but no bloo come out so she pushed the syrnge back up to try again
no it didn't
she tried atleast a couple of times
So your sample was not taken?
I mean they were not able to draw blood in the end of it all?
yes after she tried a few times of pusing the syringe up and down
whats the thing called at the end of th bottle what they pull to get your blood out? is it a syringe or am I wrong cause I may have you confused if I aint saying he right thing
and she used the same syringe, is that right?
There is a needle
And there is a bottle attached to it.
The bottle has a vacuum in it.
she puts the needle in then a bottle attached and the a syringe on the end aint there or I it called vaccum?
well yes she pulled the vaccum up and down few times
so if she was doing that was air flling the bottle
Air cannot fill up the bottle unless she took out the needle completely without blood being in the bottle. There is no air in our body or under the skin or there is no way for air to enter the bottle from underneath the skin.
oh right okay so as she is under my skin vein or not as she was pulling the vaccum in and out air was not filling that bottle I just though if there was no blood coming well would air be filling
so only if she was getting blood then pushed it backup abit woud that of caused air
That is not possible. Air cannot go into the bottle unless the needle is taken out completely.
right okay thanks you that's helped me a lot
and stopped my worrying
Was I able to clear your doubts?
how would air get in cause I have heard about air going in is that only in blood was in the bottle then she pushed back up
Usually the stories on the internet of air going in are when one has an IV line attached.
It does not happen when we draw blood like this.
Or the other possibility is when we are giving an intravenous injection to a patient.
It does not happen while drawing blood.
yes with you
Is that it or you want to ask more questions?
