Abstract
The detection of intravascular bubbles with transcutaneous Doppler ultrasonic bubble detectors is widely used in decompression research. The acoustic signals returned by the Doppler equipment are complex and require interpretation by trained Doppler raters in order to detect and categorize bubbles according to classification schemes such as the Kisman-Masurel (KM) code. This interpretation involves a degree of subjectivity and the question remains as to the comparability of scores assigned by different raters. This question must be answered to validate the technique, to allow the divers in one experiment to be divided into groups and each group to be monitored by a different rater, to allow the results of different experiments to be combined, and to allow analysis of large collections of data. Two studies were used to investigate this problem. TRUNCATED
