Carotid Body O2 Chemoreception: Respiratory and Nonrespiratory Aspects

摘要

>The respiratory and nonrespiratory hypotheses of O₂ chemoreception in arterial chemoreceptors have been compared to provide a perspective that both mechanisms can potentially coexist. The nonrespiratory membrane mechanism operates at a relatively higher level of PO₂ and that respiratory metabolic mechanisms at a lower level. The two mechanisms may overlap in the intermediate range of PO₂.
