Decompression Dilemma page 2A University of Wisconsin team led by researchers R. Tass Dueland and Charles Lehner is concerned that dive tables and computers might not adequately account for a fairly common diving pattern called "bounce" diving, whereby recreational scuba or commercial divers make many dives to different depths and of different durations in a day's diving. Studies of recreational divers who practice "bounce" diving have found that these divers can incur damage to bone tissue, a condition called dysbaric osteonecrosis (DON). In turn, DON can later lead to painful and permanently disabling arthritis. In addition, studies of recreational divers, especially among those engaged in deep diving, also have shown evidence of brain lesions. In their current study, the University of Wisconsin researchers will collect the "dive profiles" from high-risk, repetitive divers such as commercial seafood divers in Maine and Puerto Rico. This critical information can be used to more accurately determine the level of risk faced by recreational scuba divers. This risk can then be reduced through education, new medical treatments, and better diving guidelines and equipment. |
