Abstract
Although there may be many mechanisms associated with decompression sickness, the most probable initiating factor is still believed to be the formation of bubbles. Since bubbles interact strongly with sound waves, considerable research has been gone into the detection of bubbles in humans and animals by ultrasonic methods. The ultrasonic scanning method enables the detection of gas bubbles in tissue and the Doppler method the detection of moving bubbles in the circulatory system. This review article deals primarily with the Doppler method, its uses, bubble classification schemes, automatic bubble detection systems, and applications for decompression and other diving related studies. There is a good correspondence between decompression sickness and Doppler-detected bubbles and bubbles can be used as indicators of decompression stress.
