Steady-state ventilatory response

In the chemoreflex model the respiratory control system acts like a chemostat. This is consistent with the well-known experimental observation that ventilation increases with increasing chemical stimulation. The steady-state ventilatory response to CO2 inhalation is given by ... 

In an extension of Gray s early work, Lloyd and Cunningham (38) tried to quantify the ventilatory response at steady state in terms of the alveolar 02 and C02 tensions. By having subjects breath gas mixtures high in C02 at different alveolar oxygen partial pressures, the curves shown in Figure 5 were obtained. Based upon these observations, the steady-state ventilation was described by...
