Last year, I tried to draw attention in the dekoblog to disturbing reports of carbon monoxide (CO) in breathing gas. For example, an Italian technical diver in Sharm el-Sheikh discovered helium contaminated with carbon monoxide (CO) in the diluent before a CCR dive. The industry is now addressing this problem. Halcyon will soon launch the first multi-gas analyser that can measure not only oxygen and helium, but also detect carbon monoxide. Halcyon Trisense Symbios It is sus

A 50-year-old diver went diving in a Swiss lake with his closed-circuit rebreather (CCR). The plan was to dive to a depth of around 55 meters with a bottom time of approximately 20 minutes (time until leaving the depth). Compressed air was used as the diluent, at a constant oxygen partial pressure of 1.3 bar. The last decompression stop was at 6 meters. The diver complied with all decompression requirements and ended the dive after a total of 54 minutes. However, about 30 min

Ein 50-jähriger Taucher unternahm in einem Schweizer See einen Tauchgang mit seinem Closed-Circuit-Rebreather (CCR). Geplant war ein Tieftauchgang auf rund 55 Meter mit einer Grundzeit von etwa 20 Minuten (Zeit bis zum Verlassen der Tiefe). Als Diluent kam Pressluft zum Einsatz, bei einem konstanten Sauerstoffpartialdruck von 1,3 bar. Der letzte Dekompressionsstopp erfolgte auf 6 Metern. Der Taucher hielt sich an sämtliche Dekompressionsverpflichtungen und beendete den Tauchg
