Accelerated Decompression from Saturation at 132 Feet of Sea Water With Isobaric oxygenation at 60 Feet of Sea Water

摘要: Abstract : Survivors of a disabled submarine (DISSUB) would experience rise in internal pressure, and, if awaiting rescue long enough, become saturated increasing their risk decompression sickness (DCS) to nearly 80% Previous work has demonstrated that breathing hyperbaric oxygen before reduces the DCS. A combination pre-breathe, coupled with shorter schedule enable safe extraction survivors from DISSUB for subsequent re-pressurization chamber controlled on surface. Yorkshire swine (70 kg) were catheterized an external jugular catheter via Seldinger technique and allowed recover. Subjects exposed 132 feet seawater (fsw) 22 hr, then decompressed one 3 possible profiles (staged, rapid, mixed gas). The accelerated examined here supports its consideration emergency situations such as DISSUB. Further schedules pre-breathing merit additional study.
