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 correct reduced oxygen levels. Treatment in a hyperbaric chamber is occasionally needed in these cases.

Air embolism is one of the leading causes of death in the diving community. Air embolism can be caused by a number of factors — most commonly diving — but certain medical procedures can also cause gas bubbles in the blood.

The exact prevalence of air embolisms is not known; more minor cases may go untreated and can be without symptoms. This article will look at the causes, symptoms and diagnosis of air embolism. It will also include ways to avoid the condition when diving.

An embolism, in general, refers to anything untoward that has become trapped within the vascular system. An air embolism, specifically, is a bubble, or bubbles, of gas trapped within the blood vessels.

The bubbles will, at some point, cut off the blood supply to a particular area of the body. Air embolism can easily cause significant and permanent damage to the central nervous system and as such must be treated as an emergency. A venous embolism is not as serious as an arterial embolism, which is itself not as serious as a cerebral embolism.

However, all of the above have the potential to cause severe damage to organs and systems if left unchecked. Some medical procedures can cause small amounts of air to enter the venous system; via an intravenous drip, for instance.

In general, these are stopped at the lungs and do little or no harm. In rare cases, they can reach the heart and disrupt its workings. Arterial gas embolisms are much more serious. The embolism might potentially prevent oxygenated blood from reaching the target organ and cause ischemia an inadequate blood supply to an organ ; if the heart is affected it can produce a heart attack.

If an arterial gas embolism reaches the brain, it is referred to as a cerebral embolism and can cause a stroke. An injection of ml of air into the cerebral circulation can be fatal.
