摘要
The effect on CO2 storage and elimination of variations in the slope and intercept of the ventilatory response to CO2 curve was examined. Theoretical and experimental results show that although CO2 elimination rate following a transient ventilatory disturbance in decreased at low ventilatory response slopes, this decrease can be compensated by elevated PCO intercepts, or thresholds. Conversely, high CO2 elimination rate following a ventilatory disturbance due to a high ventilatory response slope can be off-set by a depressed PCO threshold. The results suggest that elevated thresholds which often accompany depressed ventilatory response slopes may be part of a compensatory mechanism for minimizing transient hypercapnia and acidosis. © 1978.
