Title Tolerance and ventilatory response to inhaled CO2 during exercise and with inspiratory resistive loading.
Bibliographic information 1979, Vol.22, No.1, p.43-53. 19 ref.
Abstract The use of self rescuers in mines is likely to be associated with inhalation of CO2. This study investigates tolerance to the effects of 2, 3, and 4% CO2 under conditions similar to those of miners wearing a self-rescuer. The average minute volume increased with CO2 concentration. Individuals showed considerable differences. A majority of subjects experienced breathlessness and headache when inhaling 4 and 5% CO2. The design of respirators for use under conditions in which increased CO2 might be inhaled should allow for the resulting increased ventilation.
