From a medical point of view, helium is of little relevance outside of diving. Accordingly, its kinetics have been insufficiently studied in comparison to other inert gases used in medical research and diagnostics, for example as tracers (1). To date, the helium algorithms used in diving medicine are based predominantly on the data set published by Bühlmann.

Helium besitzt ausserhalb des Tauchens kaum Relevanz. Entsprechend ist seine Kinetik im Vergleich zu anderen Inertgasen, die in der medizinischen Forschung und Diagnostik beispielsweise als Tracer eingesetzt werden, nur unzureichend untersucht (1). Bis heute beruhen die in der Tauchmedizin verwendeten Helium-Algorithmen überwiegend auf dem von Bühlmann publizierten Datensatz.

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
