Abstract:

Adaptation to CO2 produces a typical breathing pattern of increased tidal volume and lowered respiratory rate. Anatomical and physiological deadspace, as well as arterial-alveolar CO2 and O2 gradients, are increased under these conditions. The relationship of these findings with the well-known respiratory response to high CO2 concentrations after CO2 adaptation is discussed. Evidence for CO2 adaptation in routine diving is presented.
