The interior air of a simulated underwater habitation was continuously washed or scrubbed with sea water by means of a gas exchanger of the venturi type. The sole method for supplying oxygen and removing carbon dioxide was the scrubbing process. A microburner placed inside the experimental habitation chamber continued to burn until it was intentionally extinguished. Two rats maintained in the chamber for 8 hours suffered no discernible ill effects.
