Figure 1. Effect of 4 mg kg⁻¹ acetazolamide (i.v.) on the hyperoxic CO₂ sensitivities of the peripheral and central chemoreflex loops.

Effect of acetazolamide (4 mg kg⁻¹, i.v.) on the CO₂ sensitivities of the peripheral (S_P, left panel) and central (S_C, right panel) chemoreflex loops during hyperoxia. Each animal is represented by one symbol. Diagonal line represents line of identity.
