Chamber Carbon Dioxide and Ventilation
Abstract
Maintenance of atmospheric carton dioxide (CO2) concentrations within physiologically acceptable limits is critical to the safe operation of hyperbaric chambers and manned diving systems. Quantitative understanding of CO2 accumulation in such systems is required to specify minimum ventilation rates and CO2 scrubbing capacities. Quantitative expressions are derived for computing the maximum carbon dioxide partial pressure (Pco2) attained ins well-stirred chamber at constant temperature and pressure during continuous and intermittent ventilation and for estimating the time course of CO2 accumulation in such a chamber where an internal scrubber continuously removes CO2.
