Construction well divers in Taiwan reportedly suffer a high prevalence of dysbaric osteonecrosis.
We studied five divers working at the same construction site.
We recorded their diving methods, diving depths, bottom times, work pattems, water temperatures, body temperatures, and heart rates.
We also monitored gas bubbles in the subclavian vein in selected dives.
A crude but effective hot-water system protected divers against hypothermia and allowed them to work in 24°-27°C water.
Divers worked approximately 6.6 h a day and progressed approximately 3.0 m a day while excavating an average of 148 buckets of sand and rock each weighing 49.5 kg.
The divers sustained a heart rate increase of49%. Sixty percent of their equivalent single dive bottom times exceeded the U.S. Navy's no-decompression limits.
Two cases of venous bubbles were detected, and one of these divers showed symptoms of decompression sickness.
The prolonged bottom time and lack of a decompression schedule probably contributed to a risk of decompression sickness and dysbaric osteonecrosis.
