Venous Air Embolism

  • Carl J. Borromeo


Gas embolism refers to the abnormal presence of gas within the circulatory system. It is a complication that is known to occur with various surgical, therapeutic, and diagnostic procedures, and as the result of trauma. Gas embolism may be asymptomatic or may result in immediate cardiovascular collapse. The type and severity of sequelae depend on the composition and amount of gas involved, the rate and location of entry, and patient characteristics such as size, cardiopulmonary reserve, and presence of an intracardiac right-left communication. An understanding of the etiologies and pathophysiology of gas embolism is important in order to recognize, treat, and, most importantly, prevent this potentially catastrophic complication.
