Definition
- Noun:
- A condition caused by the formation or introduction of air bubbles in the blood vessels or tissues, obstructing circulation: This is the primary medical meaning, often resulting from rapid decompression, such as in scuba diving, or from medical procedures.
- The pain and physiological effects resulting from a rapid change in ambient pressure: This meaning specifically refers to the symptoms, like joint pain, caused by nitrogen bubbles forming in the body upon ascent from depth or during high-altitude flight.
Usage Examples
- Noun:
- The diver was treated for aeroembolism after ascending too quickly from the deep wreck.
- A rare complication of the central line insertion was an aeroembolism.
- Pilots are trained to recognize the symptoms of aeroembolism, such as sharp pain in the joints.
Advanced Usage
- Medical Context: The term is used precisely in aviation and diving medicine. It is often synonymous with decompression sickness or "the bends" when referring to the formation of inert gas bubbles. However, aeroembolism can also refer specifically to an air embolism introduced iatrogenically (by a medical procedure).
- The case study differentiated between an aeroembolism from a misplaced syringe and decompression sickness from diving.
Variants and Related Words
- Decompression Sickness (DCS) (noun): A broader condition often encompassing aeroembolism, caused by dissolved gases coming out of solution to form bubbles in the body upon depressurization.
- Air Embolism (noun): A more general term for the blockage of a blood vessel by one or more air bubbles. Aeroembolism is a specific type of air embolism.
- The Bends (noun, informal): A common colloquial term for decompression sickness, typically manifesting as joint pain.
- Embolism (noun): The general medical term for the blockage of a blood vessel by a foreign substance or a blood clot.
Synonyms
- Air embolism: Blockage by an air bubble.
- Gas embolism: Blockage by a bubble of gas.
- Decompression sickness: Illness from bubbles forming due to pressure change (specifically when the gas originates from within the body).
Related Phrases (Medical Terminology)
- Arterial gas embolism (AGE): A serious condition where gas bubbles enter the arterial circulation, often considered a severe form of aeroembolism.
- The patient's neurological symptoms pointed to a cerebral arterial gas embolism.
- Venous air embolism: Air bubbles entering the venous system.
Notes
- Aeroembolism is a technical term primarily used in medical, aviation, and diving contexts. It is not used in everyday conversation. The condition it describes is a serious medical emergency requiring immediate treatment, often in a hyperbaric chamber.
Noun
- pain resulting from rapid change in pressure
- obstruction of the circulatory system caused by an air bubble as, e.g., accidentally during surgery or hypodermic injection or as a complication from scuba diving
