A Study of Carbon Dioxide Elimination from Scuba, with Standard and Modified Canisters of the U. S. Navy Closed-Circuit Oxygen Rig

摘要

The canister from a U. S. Navy Standard Oxygen ClosedCircuit Breathing Apparatus was modified to accomodate reduced loads of pellet Baralyme. Polystyrene rods, inserted longitudinally, were used to occupy the vacated intracanister space. In a controlled laboratory environment, and with a mechanical respirator for the simulation of respiratory and CO2 production values, the relationships between absorbent weight and swimming duration were determined. A number of canister design and absorbent function characteristics were concurrently studied.
