Air embolism
Other causes of air embolisms
Air embolisms alsooccur during surgery or other medical procedures, but this is rare.
In hospitals and health centres, care should be taken to prevent this. For example:
- before injections, air should be removed from syringes and intravenous lines
- catheters or other tubes inserted into the body should be inserted and removed using a technique that minimises the possibility of air getting into the blood vessels
- patients should be closely monitored to help ensure air bubbles don't form in blood vessels during surgery
Air embolisms resulting from surgery, anaesthesia or other medical procedures can be difficult to treat. Treatment is usually needed to support the heart, blood vessels and lungs.
For example, fluids may be used to treat a fall in blood pressure and oxygen may be given to reduce levels of other gases in the blood vessels.

Introduction
An air or gas embolism is a serious problem that can affect scuba divers. Read about the causes, symptoms and treatments.
How serious is it?
The seriousness of the blockage depends on which part of the body the affected blood vessel supplies blood to and the size of the air bubble. For example, an air embolism in: the arteries to the bra
Warning signs
Divers should always be carefully monitored by their colleagues and supervisors so any air or gas embolism can be immediately identified and treated. Signs and symptoms of an air embolism can include
Treating air embolisms
If a diver develops an air embolism, the only effective treatment is immediate recompression treatment in a special pressurised room called a hyperbaric chamber. The diver should be given 100% oxygen
Preventing an air embolism while diving
The following advice can help reduce your risk of developing an air or gas embolism when diving. Limit the depth and duration of your dives. Come up to the surface slowly and always perform safety
