air embolism

The presence of gas in blood vessels, which is most significant in the coronary and cerebral arteries. An estimated 100 cc of gas (air) may suffice to cause death, as it blocks blood flow, not unlike a vapour lock in a hydraulic system. To document AE at autopsy, the organ must be opened underwater to detect bubbling.
