Visiting patients, seen several times that nurses pay no attention to bubbles flowing into intravenous fluid hose.  Verbally spanked several occasions the nurses in charge,  like they do not pay attention nor care about this.

How dangerous is it ?   I do not know if is because some fitting is not tight, or else.  What happens with bubbles flowing into narrowing arteries ?

 

There should be a bubble trap under the bag. You might see bubbles go from the bag to the bubble trap.

Thanks,  StringJunky.   Am referring to bubbles traveling by the hose into the body.  Perhaps there is different kinds of bags or equipment.  With the dripping chamber or not.

I brought up similar concerns last time I was in and was told it wasn't actually a huge deal. Apparently taken care of by the lungs if in a vein.

I have to toss a couple of things to the table...

Blood in contact with air promotes coagulation.  That cannot be good.

Air embolia is neither a good thing...  ----> https://www.nhs.uk/conditions/air-embolism/

You need quite a large amount for that to happen. More than accidentally trapped bubbles in syringes.
