Abstract
The Doppler ultrasonic technique is now widely used for detection of gas bubbles in divers. At DCIEM, the technique has been used to monitor divers in three series of bounce dives on air and two saturation dives. Our results have been supplemented through cooperative research with both French and United States Naval laboratories. The principles of the Doppler ultrasonic technique will be described. Results will be presented illustrating the use of the technique as a tool to classify the decompression stress associated with experimental dives. Ultrasonic techniques can also be used to obtain more basic information about decompression bubbles and to obtain diagnostic information about the diver but further research is required in all areas.
