Air embolism, also known as a gas embolism, refers to a condition where gas bubbles enter the bloodstream and obstruct blood flow. It can occur due to various reasons such as during surgery, diving, or even during invasive medical procedures. Some synonyms for air embolism include gas embolism, pulmonary barotrauma, arterial gas embolism, and venous gas embolism. Each of these terms refers to a specific type of air embolism that affects different parts of the body. Gas embolism typically affects divers when bubbles form in the bloodstream during sudden or rapid decompression. Meanwhile, venous gas embolism is when air bubbles enter the venous system, and it can lead to severe symptoms such as shock, cardiac arrest, and even death.
