SCUBA diving has several risks associated with it from breathing air under pressure--nitrogen narcosis, barotrauma and decompression sickness (the bends). Trimix SCUBA diving involves regulating mixtures of nitrogen, oxygen and helium in an attempt to overcome the risks of narcosis and decompression sickness during deep dives, but introduces other potential hazards such as hypoxia and oxygen toxicity convulsions. This study reports on a seizure during the ascent phase, its potential causes and management and discusses the hazards posed to the diver and his rescuer by an emergency ascent to the surface.
水肺潜水会因呼吸加压空气而产生一些风险,如氮麻醉、气压伤和减压病(潜水病)。混合气体潜水(例如使用氮、氧和氦的混合气)是为了尝试克服在深潜过程中麻醉和减压病的风险,但这也引入了其他潜在的危险,如缺氧和氧中毒性抽搐。本研究报告了在上升阶段发生的一次癫痫发作,探讨了其可能的原因和处理方法,并讨论了紧急上升到水面对潜水员及其救援人员构成的危险。
