We examined the effects of different modes of airway CO2 load on the ventilation-CO2 output (VE-VCO2) relationship during mild to moderate exercise. Four young and three older male subjects underwent incremental steady-state treadmill exercise while breathing a mixture of CO2 in O2 (CO2 loading) or 100% O2 with and without a large external dead space [DS loading and control (C), respectively]. During DS loading, the elevated arterial PCO2 (PaCO2) remained constant from rest to mild exercise and… CONTINUE READING
