Title Decompression bubbles in caisson workers.
Bibliographic information 30 Oct. 1977, Vol.32, No.4, p.529-533. Illus. 11 ref.
Abstract 152 tests to detect precordial decompression bubbles were performed with the Doppler ultrasonic bubble detector in 91 caisson workers. The results were: most of the bubble signals appeared and reached a maximum within 60 minutes after decompression; appearance of or increase in blood bubbles was stimulated by clenching the fist or raising the arms above shoulder height; bubble signals were heard in 88 (58%) of tests, including the 16 cases of decompression sickness requiring treatment; 48 cases with bubble signals were asymptomatic; occurrence and grade of decompression bubble signals in successive operations seemed to depend on decompression schedules.
