Title: [abstract] OXYGEN TOXICITY SEIZURES IN HYPERBARIC CHAMBER INSIDE ATTENDANTS.
Author: Wreford-Brown, CE; Hampson, NB
Abstract: Introduction: The incidence of central nervous system oxygen toxicity seizures (CNSOTS) among patients during routine hyperbaric oxygen treatment is estimated to be 1 in 10,000 exposures. However, only 2 incidents of CNSOTS among chamber inside attendants (IAs) have been reported. This study examines the incidence of CNSOTS among IAs in North American hyperbaric treatment chambers during the past five years. Materials and Methods: Every chamber in the United States and Puerto Rico listed in the 2001 UHMS Chamber Directory was surveyed by mail, phone or E-mail to query practice patterns for IA decompression in multiplace hyperbaric chambers and to record the details of any CNSOTS among IAs from 1996-2001. Overview: Of 376 facilities surveyed in 2001, all responded. A total of 56 chambers were closed or no longer conducted clinical hyperbaric oxygen treatment. Of the 318 operational chambers, 67 were multiplace only, 237 monoplace only, and 14 had both types of chambers. Among the 81 multiplace chamber facilities, 76 use oxygen in the decompression of IAs. During the past 5 years, none had experienced CNSOTS in their IAs. The maximum pressure at which the IA breathed 100percent oxygen varied from 1.3 atm abs to 3.0 atm abs, with a mean pressure of 2.6 atm abs and a median of 2.8 atm abs. The method of IA oxygen delivery used by all chambers was by an aviator style mask. Thirty facilities required that the mask be strapped in place, 30 facilities required that the mask be held manually, and 16 facilities allowed the option of either. Conclusions: We identified no cases of CNSOTS among IAs in multiplace chambers in the past 5 years, despite the fact that IAs are routinely administered oxygen under pressure. oxygen toxicity, seizures, attendant, hyperbaric
