"SCUBA divers as a result of gas bubble formation in the blood, which occurs due to rapid reduction in the ambient pressure during a diver's ascent"
"May show some of the above plain radiograph features in greater detail, as well as allow direct visualisation of gas in the systemic veins (usually seen along the injection trajectory e.g. subclavian, innominate, and SVC) versus the positive contrast, right-sided cardiac chambers, or main pulmonary arteries."

"Training and periodic orientation of staff dealing with automatic injectors in the radiology suite to avoid intra-vascular inadvertent air injection and recognise the manifestations of air embolism as early as possible is a must to avoid this serious complication"
"Durant's manoeuvre: position the patient in a left lateral decubitus in Trendelenburg position (head down), with the aim to prevent the gas passing from the right heart into the pulmonary arteries"

"The risk of death is affected by both the amount of gas and the speed of introduction; the minimum lethal volume and injection rate in humans are thought to be around 300-500 mL and 100 mL/sec, respectively 4."
