A chawber has been designed so that dogs can be exposed for prolonged periods to abnormal atmospheres. The concentrations of CO2 and O2 are continuously controlled and recorded. Exposure of dogs to approximately 3 percent CO2 in air for 6 days or more resulted in a decrease in the ventilatory response to CO2. In control dogs the breathing of 50 per cent oxygen for 30 minutes was associated with a slight to moderate increase in ventilation without a significant change in arterial pCO2. After acclimatization to CO2 oxygen breathing was associated with Little change in ventilation but with a rise in arterial pCO2.
