Abstract:

The Prototype MK 12 SSDS, Helium-Oxygen System, was evaluated to test the ability of the system to support a working diver. The study was performed in two parts. First, helmet carbon dioxide levels during graded exercise were measured to ensure that helmet ventilation is adequate to support a diver performing sustained heavy work, equivalent to an oxygen consumption of 3 liters per minute. Secondly, cannister effluent carbon dioxide levels were measured during prolonged moderate work, equivalent to a carbon dioxide production of 1.5 litersminute, to establish cannister duration. Analysis of the data clearly shows that while helmet ventilation is adequate to support a diver performing sustained heavy work for short periods, cannister duration was inadequate to support moderate work throughout an operational dive.
