Abstract

Abstracto1.Oxygen consumption (M_O₂) may be independent or dependent upon environmental partial pressure of O₂ (P_IO₂). The degree of regulation depends upon the species, the physiologic state of the individual, as well as temperature and salinity of the environment.2.A model of gas exchange is presented where M_O₂ depends upon the P_O₂ gradient between the environment and mitochondria and on the O₂ conductance (G_T) through the animal: M_O₂=G_r (P_iO₂-P_mO₂).3.Regulators compensate for a fall in P_IO₂ by increasing O₂ conductance such as via increased ventilation (V_G) or circulation. Different strategies are evident by examining changes in V_G and O₂ extraction and percent utilization.4.Three types of conformers are designated depending upon the extent to which they compensate anaerobically for a drop in P₁O₂.5.Five types of recovery patterns from hypoxia are designated depending upon the nature of the O₂ debt.
