Final answer:
Hyperventilation causing respiratory alkalosis can be induced by factors such as anxiety, fever, liver failure, and salicylate toxicity, which lead to excessive CO₂ loss and an overly alkaline blood pH.
Step-by-step explanation:
Hyperventilation causing respiratory alkalosis can be induced by several factors, including anxiety, fever, liver failure, and salicylate toxicity. These conditions can lead to an excessive loss of CO₂ and subsequent decrease in blood carbonic acid levels, making the blood too alkaline.
Anxiety often precipitates hyperventilation as a part of the body’s 'fight or flight' response, which can lead to respiratory alkalosis. A fever can increase the body’s respiratory rate to cool down, potentially causing hyperventilation and alkalosis. In liver failure, the body’s balance of acids and bases can be disrupted, which may contribute to altered breathing patterns and respiratory alkalosis. Lastly, salicylate toxicity, often due to aspirin overdose, can initially cause metabolic acidosis, which the body attempts to compensate for by hyperventilating, thus leading to respiratory alkalosis.
