WebIndividuals with high loop gain tend to experience periodic declines in respiratory drive, resulting in decreased activation of the upper airway dilator muscles, leading directly to repetitive breathing events (i.e., OSA), an important ventilatory regulator of which is carbonic anhydrase, which is also the rationale for CAIs in the treatment of …
