Several toxic agents can induce respiratory alkalosis by stimulating the respiratory center in the brain, leading to hyperventilation. Some common substances include:
- Salicylates: Overdose of salicylates, such as aspirin, initially causes hyperventilation and respiratory alkalosis before leading to metabolic acidosis. - Catecholamines: Elevated levels due to exogenous administration or endogenous release in response to stress can stimulate respiration. - Theophylline: Overdose can lead to central nervous system stimulation and increased respiratory rate. - Carbon monoxide: Although primarily causing hypoxia, it can also lead to hyperventilation as a compensatory mechanism.
