Low-dose acetazolamide reduces CO(2)-O(2) stimulus interaction within the peripheral chemoreceptors in the anaesthetised cat.

Abstract

1. Using the technique of end-tidal CO(2) forcing, we measured the effect of the carbonic anhydrase inhibitor acetazolamide (4 mg kg(-1), I.V.) on the CO(2) sensitivities of the peripheral and central chemoreflex loops both during hyperoxia and hypoxia in 10 cats anaesthetised with alpha-chloralose-urethane. 2. In the control situation, going from hyperoxia… (More)
