Abstract Ventilatory Response to Carbon Dioxide during Moderate Exercise: Masayoshi TAKAHASHI, et al. National Institute for Resources and Environment-Elevated carbon dioxide (CO2) concentration is one of the most important physiological stressors with closed-circuit breathing-apparatus (CCBA). We determined the ventilatory response to CO2 during moderate exercise by measuring the relationship between VE and PETCO2. Based on our findings, it is recommended that the permissible inhaled CO2 limit for CCBA in the Japan Industrial Standard (JIS) be lowered from 3% to 2%, and that the members of a rescue or fire fighter team who use CCBA be selected on the basis of their ventilatory sensitivity to CO2.
