When an air bubble enters a vein, it’s called a
venous air embolism
. When an air bubble enters an artery, it’s called an arterial air embolism. These air bubbles can travel to your brain, heart, or lungs and cause a heart attack, stroke, or respiratory failure. Air embolisms are rather rare.

Can you get an air embolism from a PICC line?
Because a PICC line is a central venous catheter, it carries with it the same risk of air embolism while it is in place as other CVADs. However, because it is peripherally inserted, it
presents negligible risk of symptomatic air embolism during removal
.
How do I unblock a PICC line?
- Attach the 10 ml syringe with the urokinase 5000 units in 2 ml to the 3-way tap, at a 90 ̊ angle to the PICC.
- Open line clamp (if there is one)
- Open 3-way tap to the empty syringe and blocked PICC and draw back on the plunger of the syringe as far as it will go.
How much air in IV line can cause embolism?
Therefore, the lethal volume of air may be greater in adults with normal cardiac function. In summary, estimates of
200–300 ml air
have been reported to be lethal.
Can a PICC line damage the heart?
Irritation of the heart: If the line is too close to the heart, or in the heart, it can irritate the heart and cause a cardiac arrhythmia, an abnormal heart rhythm. If the problem is not diagnosed quickly, the PICC
line rubbing against the beating heart can cause damage to the heart muscle or valves
.
What can go wrong with a PICC line?
- Bleeding.
- Nerve injury.
- Irregular heartbeat.
- Damage to veins in your arm.
- Blood clots.
- Infection.
- A blocked or broken PICC line.
Why do you hold your breath when removing a PICC line?
Ask patient to hold their breath at the end of expiration before the last 15cm of the PICC is removed. During inspiration, negative intrathoracic pressure can encourage air to enter the exit site and cause an air embolism.
Can you sleep on your side with a PICC line?
Find a comfortable sleeping position: It’s generally best to sleep on your back to prevent any friction or movement to the port, but
some prefer to sleep on their side
. If you must sleep in any position other than flat on your back, sleep on your non-port side.
What is the alternative to a PICC line?
The TIVAD (totally implantable vascular access device) is a long hollow tube that is inserted into one of the large veins in the body. TIVADS are also called Ports or Portacaths. Another PICC line alternative is
the Tunneled CVC (central venous catheter)
.
What happens if you don’t flush a PICC line?
Risks associated with drawing blood specimens from a PICC include
infection and catheter occlusion or rupture
if the PICC isn’t flushed properly afterward. For patients with severely compromised venous access, though, the PICC may be the only option for drawing blood specimens.
How often do PICC lines need to be flushed?
Flushing a PICC
The PICC needs to be flushed
once weekly
with 10mls of 0.9% Sodium Chloride to maintain patency when not in use or after any infusion or bolus injection. There is no need to withdraw blood into the syringe prior to a routine flush with saline (RCN 2010).
How long does PICC line last?
A PICC can stay in your body for your entire treatment,
up to 18 months
. Your doctor will remove it when you don’t need it anymore. Having a PICC shouldn’t keep you from doing your normal activities, such as work, school, sexual activity, showering, and mild exercise.
Does an air embolism go away?
A pulmonary
embolism may dissolve on its own
; it is seldom fatal when diagnosed and treated properly. However, if left untreated, it can be serious, leading to other medical complications, including death.
What should you do if you suspect an air embolism?
Air or gas embolisms can cause serious and potentially fatal conditions, such as a stroke or heart attack. Call 999 and
ask for an ambulance
if you or someone you’re with feels unwell after scuba diving and you suspect an air or gas embolism.
