SpletBackground: Carbonic anhydrase inhibitors such as acetazolamide cause a mild metabolic acidosis and may stimulate breathing. Some patients with severe chronic obstructive pulmonary disease (COPD) develop chronic hypercapnic ventilatory failure. In theory, they may benefit from use of these drugs with a fall in arterial carbon dioxide level (PCO2) and … SpletVentilation is influenced and regulated by chemoreceptors for Pa CO 2, PaO 2, and pH located in the brainstem, and in the aortic and carotid bodies as well as by neural impulses from lung stretch receptors and impulses from the cerebral cortex.

Responses of laryngeal receptors selected for their responsiveness to 10% intralaryngeal CO2 were recorded in single fibers of the superior laryngeal nerve at a wide range of systemic PCO2 values and before and after carbonic anhydrase inhibition in anesthetized, paralyzed, ventilated cats.

Splet21. jun. 2024 · Respiratory acidosis is a state in which there is usually a failure of ventilation and an accumulation of carbon dioxide. The primary disturbance of elevated arterial PCO2 is the decreased ratio of arterial bicarbonate to arterial PCO2, which leads to a lowering of the pH.
