Title: [abstract] WORKING DIVES AT ALTITUDE: A PRACTICAL EXPERIENCE
Author: Smookler, M; Cianci, PE
Abstract: BACKGROUND: These is scant data providing guidance for working dives at altitude. METHOD: We report greater than 200 dives at altitudes from 900 to 1900 meters, all involving moderate to heavy work loads, e.g., changing out 200 kg valve stems in mountain dams. Depths of working dives raned from 15 to 150 feet (4.57 to 45.7 meters) and involved no decompression, standard decompression, and surface decompression with oxygen. Altitude corrections (Cross) were utilized for all dives at altitudes greater than 1000 feet (304.8 meters). An ascent rate of 25 ft (7.62 meters) per minute was used for all dives, and all were conducted using surface supplied air and Superlite 17 or 27 helmets. Thermal protection was afforded by the use of dry suits, with the occasional diver opting for use of a wet suit. Thirty-nine percent of all dives involved surface decompression with O2 in accordance with US Navy surface decompression procedures without modification. RESULTS: There were no cases of decompression illness or diver injury. CONCLUSION: While current guidelines for diving at altitude would appear to have been directed primarily to the sport diver, these data suggest that dives at altitude involving heavy work loads, even those utilizing surface decompression on oxygen, can be done safely using the described protocols.
