Gas embolism is a medical condition that occurs when gas bubbles enter the bloodstream and create blockages or damage to the circulatory system. There are several synonyms for this condition, including gas embolus, gas bubble embolism, and arterial gas embolization. These terms are often used interchangeably and refer to the same medical condition. Other related terms include decompression sickness, the bends, and air embolism. Gas embolism can be a life-threatening condition and requires immediate medical attention.
