Dr. Shahzad MD :

Hi there. Thank you for your question. I will be helping you out with your queries

Dr. Shahzad MD :

A small amount of air is nothing to worry about.

Customer:

hya

Dr. Shahzad MD :

It requires at least 40-50 ml of air to potentially cause any issues

Customer:

she did do it a few times is this a concern

Dr. Shahzad MD :

So no worries.

Dr. Shahzad MD :

No it is not a concern.

Dr. Shahzad MD :

That would still be a very small amount of air.

Customer:

is a blood test bottle no were near 50ml

Dr. Shahzad MD :

no

Dr. Shahzad MD :

A blood test bottle is usually around 5 ml

Customer:

oh right ok so evan tho blood was not coming out in the bottle would air actualy of ben in the bottle

Dr. Shahzad MD :

Did not get your question.

Dr. Shahzad MD :

Can you please explain your last question.

Customer:

would air of actualy been in the bottle when she pulled the syringe the first time

Dr. Shahzad MD :

When there is an empty space there would be air.

Customer:

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?

Dr. Shahzad MD :

Yes

Dr. Shahzad MD :

That is something very common.

Dr. Shahzad MD :

Done almost daily.

Dr. Shahzad MD :

They do keep pulling the syringe up and down until they hit the vein

Customer:

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

Dr. Shahzad MD :

That is right

Customer:

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

Dr. Shahzad MD :

If no blood comes out it means she was not in the vein.

Customer:

she said she was in a vein just no bloo coming out

Dr. Shahzad MD :

Blood will always come out if a vein is hit properly.

Dr. Shahzad MD :

So she either missed the vein or hit it and then the needle move.d

Dr. Shahzad MD :

moved*

Customer:

okay thank you she did try a few timesin both arms my veins had disappeared cause was cold

Dr. Shahzad MD :

You are most welcome
Wish you all the best.
I would appreciate it if you rate me by clicking on one of the smilies below.
Kindest regards

Customer:

so evn if she did pump air in tey do that to most people who theycant draw blood from

Customer:

sorry so evan if she did pump air in they do that to most people they cant draw blood from*

Customer:

yes not a problem

Dr. Shahzad MD :

Yes

Dr. Shahzad MD :

they do that to most people and even if a small amount of air goes in that is not a problem

Customer:

sorry I have payed 11 pound but not getting much detail just one word ansers

Dr. Shahzad MD :

I am here to answer your concerns.

Dr. Shahzad MD :

You can ask any number of questions until you are satisfied.

Customer:

thank you just a worried person

Dr. Shahzad MD :

Most welcome. I understand you are worried and I am here to help you in anyway else that I can.

Dr. Shahzad MD :

This session is open for any further questions.

Dr. Shahzad MD :

Rate me only when you are done asking your questions.

Customer:

no problem

Customer:

if air would of caused a problem would this of happened already got me blood done around 9 lastnight

Dr. Shahzad MD :

Yes it would have happened already.

Dr. Shahzad MD :

Air in the blood vessels causes what is called as air embolism

Dr. Shahzad MD :

And this happens instantly.

Dr. Shahzad MD :

So if this were to cause any problems you would have experienced the symptoms arleady.

Dr. Shahzad MD :

already*

Customer:

what are the symptoms

Customer:

are you really ill with them

Dr. Shahzad MD :

Shortness of breath, chest pain, increased heart rate, palpitations.

Dr. Shahzad MD :

You become severely ill actually.

Customer:

so with it been lastnight something would of happened by now

Dr. Shahzad MD :

Yes, something would have definitely happened already

Customer:

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?

Customer:

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?

Dr. Shahzad MD :

Well, usually they would go in and out at least two or three times when they do not hit a vein.

Dr. Shahzad MD :

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.

Customer:

she didn't take the needle in and out she was pulling the vaccum syringe in and out

Dr. Shahzad MD :

The vacuum syringe would almost never cause air to be pushed into the vein because of the negative pressure in it.

Dr. Shahzad MD :

So the chances of even a small amount of air going in is very low indeed.

Dr. Shahzad MD :

Are you with me?

Customer:

yes so basically no air would or probably went in

Dr. Shahzad MD :

Yes

Customer:

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

Dr. Shahzad MD :

Most likely no air went in

Customer:

I di say to her are you allowed to do tha and she said yes

Customer:

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

Dr. Shahzad MD :

If she pulled the syringe completely out then the vacuum or the negative pressure in the bottle is lost.

Customer:

what do you mean

Customer:

the needle was still in my arm she didn't pull the needle out just pulled the syringe

Customer:

pulled the syringe back no blood come out so she pushed it back up to then pull again so blood come out

Dr. Shahzad MD :

If the blood came out it means that the negative pressure was still there in the syringe

Dr. Shahzad MD :

So it is not possible for air to go into the veins when there is negative pressure in the syringe

Customer:

no blood come out this is what I am saying

Dr. Shahzad MD :

But it did come out the second time around.

Customer:

she pulled the syringe but no bloo come out so she pushed the syrnge back up to try again

Customer:

no it didn't

Customer:

she tried atleast a couple of times

Dr. Shahzad MD :

So your sample was not taken?

Dr. Shahzad MD :

I mean they were not able to draw blood in the end of it all?

Customer:

yes after she tried a few times of pusing the syringe up and down

Customer:

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

Dr. Shahzad MD :

and she used the same syringe, is that right?

Dr. Shahzad MD :

There is a needle

Dr. Shahzad MD :

And there is a bottle attached to it.

Dr. Shahzad MD :

The bottle has a vacuum in it.

Customer:

she puts the needle in then a bottle attached and the a syringe on the end aint there or I it called vaccum?

Customer:

well yes she pulled the vaccum up and down few times

Customer:

so if she was doing that was air flling the bottle

Dr. Shahzad MD :

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.

Customer:

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

Customer:

so only if she was getting blood then pushed it backup abit woud that of caused air

Dr. Shahzad MD :

That is not possible. Air cannot go into the bottle unless the needle is taken out completely.

Customer:

right okay thanks you that's helped me a lot

Customer:

and stopped my worrying

Dr. Shahzad MD :

Was I able to clear your doubts?

Customer:

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

Dr. Shahzad MD :

Usually the stories on the internet of air going in are when one has an IV line attached.

Dr. Shahzad MD :

It does not happen when we draw blood like this.

Dr. Shahzad MD :

Or the other possibility is when we are giving an intravenous injection to a patient.

Dr. Shahzad MD :

It does not happen while drawing blood.

Dr. Shahzad MD :

Are you with me?

Dr. Shahzad MD :

Anymore questions?

Customer:

yes with you

Dr. Shahzad MD :

Is that it or you want to ask more questions?

Dr. Shahzad MD :
