A LOW PRESSURE CHAMBER FOR ESTIMATION OF THE GAS EXCHANGE RATIO,

Abstract

An experimental system for exposing small laboratory animals to specified gas mixtures is described. System pressure may be set at levels up to atmospheric. A demand regulator is used to add oxygen to a pre-set pressure level, in proportion to the amount of carbon dioxide removed. Flow-meters and gas analyzers are provided for obtaining the oxygen flow rate into and the carbon dioxide removed from the system. Data from these instruments are read out as often as once a minute and are punched into IBM cards which are processed in a computer. The system is designed for experiments that last for several days or weeks. (Author)
