Air bubbles in iv picc line
My concern with this document, and many others on the same topic, is that peripherally inserted central venous catheters PICC lines are lumped in with subclavian and internal jugular central venous catheters and tunneled catheters, when the risk of air embolism on removal is not at all the same. If you have any instances of this occurring, I would be grateful if you could share this with me and encourage those involved to document these cases in the literature as evidence of the risk.
The dressing is not changed daily after removal, and the patient does not have to be observed for 30 minutes post removal. Patients are not put in the supine position for PICC removal. I am finding it hard to justify implementing your recommendations. I would be interested in your feedback on this issue.

If all precautions are taken to maintain a closed system during PICC line removal i. The Authority thanks you for calling this to our attention and providing us the opportunity to make this clarification.
Authority analysts sought additional input from Bruce Hansel, ECRI Institute, because of his extensive experience investigating catheter-related problems, including air embolism.
External Reviewer Comment Air embolism is diagnosed based on manifested signs and symptoms. Air embolism may occur with PICC line removal, but the amount of air may be so minimal that it does not produce symptoms. The absence of symptoms is not sufficient to ensure that no air has entered the vessel. However, this discussion centers on symptomatic embolism.
However, because it is peripherally inserted, it presents negligible risk of symptomatic air embolism during removal. In that regard, the precautions suggested in the Advisory article and recommended in the literature for removing CVADs are unwarranted for PICCs for two reasons: 1 the pressure gradient favoring air ingress is much lower at a peripheral site than at a more centrally located CVAD insertion site, and 2 the diameter of a PICC track through the tissue is smaller than that of most CVADs.
Furthermore, when removing a peripheral catheter, supine or Trendelenburg is less favorable pressure-wise than a more favorable seated position with the arm at waist level. To prevent air ingress when removing a peripheral intravenous catheter, the exit site needs to be lower than the heart. The same measures used for removing short peripheral intravenous catheters should be applied to PICCs. However, a PICC site may be more likely to bleed after removal because it will have a larger and more mature track through the tissues than a short peripheral intravenous catheter.
About the Authority. About Us. Media Resources. Right to Know.As an educator for Teleflex, I see many practices. My thoughts are this is absolutely nuts, crazy, stupid, I could go on. We now have lots of information about the effect of microbubbles in the circulation.
I had to read your post 3 times because I couldn't believe it. How could any clinician think this is a good idea? I agree with the previous postings. This is not a practice that I would take on as a prudent nurse.
From years past experience, patients heard saline flushing post PICC without air bubbles. The value of injecting air in this manner is low and the risk is high. I would definitely recommend a tip locator system, before advocating this weird practice! I am shocked that this is a practice that any prudent RN would use.
I have never heard of this practice. Some MD taught them this is my guess. Just like the rampant use of stiff wiring that I come accross every day it seems. My suggestion as you work for a vendor is to give this team a copy of the IFU's and inform them that what they are doing is not in the labeled use of indications. If it is not they are performing a procedure not santioned by the hospital.
That is the best you can do. I'm with Mari - I had to read this 3 times too.
I can't believe someone would be doing this practice - even if an MD showed you this. Reminds me of what our parents used to always ask us - if your friend jumped off a bridge would you too. Even in the instances of a bubble study during an echo, it is done with a physician present and in a controlled setting with probably much less air that they are injecting through this picc line. I would like your input on the following situation. Ever heard of this? What are your thoughts?
In my case, I believe a MD showed him to do that as well as read his own Xrays. Too funny cause IN doesn't allow that I could go on, but I will leave it at that. Skip to main content.

Hello fellow nurses! I have a question for you all. I've seen her 3 or 4 times before and another patient with a PICC line at my home health job, not to mention, I deal with them all the time at the Medical.Xr5 radiator
But yesterday for some reason, after I changed her dressing and hanged the cap and was about to flush, I seen a bunch of little tiny air bubbles in the line. This hasn't happened before, so of course I didn't flush, I pulled back to see if I could get the air out, I kept pulling until there was about 2 mL of air in my 10 mL NS syringe. I pushed the air out, and pulled more air out of th PICC.
At one point, I thought I was going to be able to flush, but when I tried again, I saw those air bubbles once again! After about 10 to 12 more attempts of trying to pull air out and flush, I decided not to flush the PICC line. The patient is also an RN and agreed with me. She also goes back to the oncologist on Tuesday. It makes me wonder if it was a problem with the syringe or cap?World history ancient civilizations answer key
I made sure everything was on tight. Never had this happen before!how to remove air bubbles from iv line
When I told my DON about it, she acted as if I should have flushed it anyway because it's not enough air to kill anybody. I don't understand that either, I wouldn't wanna risk it! I also never got any blood return. Has this ever happened to any of you?Sharon tate house tour
Thank you! If you were sure the caps were tight, I wonder if the catheter itself was cracked outside of the body? I would wonder if the PICC has flipped in RAD they have sometimes flipped a PICC back into place by using forceful flush, but had one patient whose PICC flipped upward when they injected meds and he began feeling the burn of the morphine; when x-ray was done to confirm location, sure enough the PICC was angled toward his head where he had been feeling the burn!

Thank you. UBBFriend: Email this page to someone! We switched pumps used to use the apple shaped pump and now using the baby bottle one. Sometimes, the air is in the line in the middle of the infusion! I called the pharmacy and they said not to worry about it. Today, after the infusion was done, I flushed with normal saline.
When I took it off the picc and put the heparin on, something i'm assuming air? Yesterday, i got air in as well and I immediately get a headache in the back of my head.Ps3 a connection error has occurred 80130128
Happened again today. I might be herxing it's scary that I never got these types of headaches before I started doing the infusions myself. Any help would be appreciated. I'm scared the air bubbles might be getting to my brain and causing damage.
Sometimes, little baby ones. I don't know how big today's bubble that shot thru my arm was. First, check to make sure that that your extension sets and end caps are secured on as they should be. Make sure that your PICC is not visibly broken or leaking in any place.
Before you start your IV's remember to prime the tubing. That means run the air out of the tubing so that the medicine drips down to the tip. Also, hold your syringe flushes upright and push the air out of them before you attach them to your PICC lines. This should help keep air bubbles out. That way you leave the bubble inside the syringe. Hopefully you won't have any more problems.
There’s an air bubble in my IV line. Should I panic?
A few bubbles every now and then won't hurt. Alot of air is not good. It was smart of you to call your pharmacist right away when you were concerned with the infusion. Hopefully everything will get easier and you'll feel better soon. I don't know if my headaches are due to the air or to the lyme flaring up. I'm scared I might have done some harm to myself.
Do you know the amount of air that's acceptable? The pharmacy said 10ml's. Is that right? Lots of things can cause headaches so it's hard to say what's causing it now. So about the air bubbles yesterday.
Take a look at your extension set, mine is 7" long.Forgot your password? Or sign in with one of these services. I am also recently new to allnurses. So would there be no difference? PeakRN specializes in Adult and pediatric emergency and critical care. The consequences and risks of air embolism depends more on the individual patient and less on the access type.
If a patient has no shunt between the left and right sides of the heart then the air will end up in the pulmonary vasculature. If the patient has a shunt such as a PDA, PFO, ASD, VSD, single ventricle pathology, surgical shunt, or any other communication diagnosed or not, and the air can enter the left side of the circulation and result in injury to the heart, brain, or other left sided vasculature.
These are typically more debilitating than right sided insults. It basically couldn't happen through a picc line though it can theoretically happen if you remove an IJ or subclavian central line with poor technique and the patient creates enough negative pressure via breathing to quickly pull in that much air - this is why you lay the patient flat, have them breathe in an hold their breath before you pull said central line, etc.
However, an arterial air embolism can be dangerous at about 1 cc of air. Thats enough to cause a stroke or MI if it gets into the arterial blood and travels to the wrong place. Most air bubbles in the venous blood are harmlessly removed from the blood when that venous blood travels to the lungs. However a patient with much of a shunt can be in more danger. Still, its possible when coughing, during mechanical ventilation, etc.
Or the patient can have a shunt caused by damaged lung tissue, etc. They would have to be pretty unlucky for a small venous air bubble to cause a damaging arterial air embolism, but it can happen. With all that said, most bubbles you see in iv tubing are substantially smaller than 1 cc anyway. Ever watched a bubble study during an echocardiogram?
They fill the heart with thousands of tiny air bubbles, and it's not considered dangerous. You don't have to sweat the tiny bubbles, whether in a picc or otherwise. Been a nurse for 40 years. NEVER have seen a single patient or heard of a single patient that was harmed by air bubbles. I did have one patient when I was doing home health who had a faulty pump unbeknownst to me. When it alarmed "air" she kept pushing the button to override it. So she pumped herself full of air.
Her mom called me in a panic because patient was SOB. DIdn't know what else to do. Called provider.
They said place on left side. OK then what? Provider had no idea. So patient layed on left side for about 30 minutes. Which is what happened and patient was fine. So do be vigilant, but relax, you'll be fine.
OP, the likelihood that you would even have a syringe with more than, say, 1mL of air inside is pretty small. The pre- filled saline flushes at my hospital have about 1mL and I either squirt it out before flushing or purposely hold the syringe with the plunger up so the air is away from the luerlock and only flush with about 9mL basically, watching what I'm doing.
When I draw a med out of a vial I always draw out the whole volume, shake the syringe a couple of times to make the air rise to the luerlock, squirt it out, and then waste appropriately if I don't actually need the whole volume.How do they get there? How do we get rid of them? And do we need to worry about them in the first place? Perhaps you have been a patient in hospital and had a drip running. And perhaps you have looked down and noticed some tiny bubbles in the IV.
Somewhat alarmed you watch as they slowly float down the tubing and then disappear up into your arm. You vaguely remember watching a TV drama where someone was killed in a hospital by the villain injecting air into their IV line.
In most cases, it would require at least 50 mL of air to result in any significant risk to life. So, you can be assured that it usually requires a very large volume of air in the IV to produce a life threatening risk of air embolism. Much more than you will typically see in your IV line. This is of particular concern in older patients and those with multiple medical problems.
So… do not be alarmed with those small air bubbles which often appear mysteriously in the line. And be assured that medical staff are always attempting to minimise the risk of them forming.
But what about when the bag is empty, can air run down the line then? If your IV is on an electronic pump, it will automatically stop once the bag is empty.
It also has bubble detectors that will stop the pump and sound an annoying alarm if any air bubbles are detected. If your IV is not on a pump, the plastic IV bag collapses as it empties forming a vacuum inside that stops any further flow.
Instead, notify a nurse. And as you can see there is really no need to obsessively watch your IV line. But to improve your knowledge and help identify potential problems to staff, here are some of the preventable things that could lead to a more significant amount of air in your IV line. Drip chamber not filled properly. This occurs when the nurse or doctor has not adequately primed the drip chamber. The drip chamber is usually marked with a fill line and if it is under filled it may increase the likelihood of air bubbles making their way into the IV line.
Especially if it is running at faster rates or if the IV tubing is jiggling around when you are being transported somewhere for example. Before connecting your IV staff will run fluid from your IV flask down through the tubing to prime it and remove all the air. If distracted or interrupted there is a risk that the tubing may not have been fully primed and it can be difficult to tell if the IV tubing is full of fluid or air on a quick glance.
An un-primed IV line presents a potential for a more significant volume of air to be accidentally infused into the circulation.
Air is added to the IV bag when injecting additives. Medical staff should ensure that there is no extra air injected from the syringe into your IV bag when adding medications or electrolytes.When was the last time you, or one of your loved ones, was in a hospital bed with an intravenous line attached to your arm and a bag of intravenous fluid hanging from an IV pole beside you?
Perhaps when the bag of fluid began to empty, a health care worker entered the room to hang another bag of the lifesaving liquid, or maybe just attach a smaller bag of medication to run into you intravenous line.
But out of the corner of your eye you noticed a large bubble of air slowly advancing down your IV line toward your arm. This explanation is usually followed by another short explanation about how it would take a massive amount of air to cause you any harm, and that there is nothing to worry about with those little bits of air.
Unfortunately, this scenario is repeated thousands of times by health care workers who still consider venous air bubbles as inconsequential, and subsequently spend their careers disregarding small amounts of air bubbles entering the venous circulation through an intravenous line.
These bubbles are often referred as iatrogenic air coming from the activity of a health care provider. What is interesting is the fact that there is absolutely no reason why any amount of air or air bubbles should be allowed to pass through an intravenous line in any patient. But more importantly, air bubbles have the potential to cause harm and are not in the best interest of the patient … let me explain why. First of all, regardless of the size of the bubble or its point of entry into our arterial or venous blood streams, bubbles or any particles entering our bloodstream are alien to our circulation and our physiology.
The bubbles are immediately coated by platelets, white blood cells and other proteins as they travel toward the right side of the heart. During their course through the bloodstream, they can damage or degrade the blood vessels delicate lining called endothelial glycocalyx and its underlying endothelial cells resulting in endothelial cell edema, inflammation, localized platelet and white cell activation and even blockages in the tiny pulmonary capillary vessels, much in the same manner that a solid or fat embolus would do.
The normal size of our capillaries microcirculation is somewhere between microns in diameter, but the bubbles trying to pass through these capillaries can be hundreds or thousands of microns larger.
If those bubbles break up and enter the arterial blood going to the brain, they have the ability to cause neurocognitive dysfunction memory loss, emotional upset, etc or stroke.
