Respiratory alkalosis occurs when there is an imbalance in the body's acidity levels due to increased respiration, leading to a loss of carbon dioxide (CO2). This condition is typically associated with hyperventilation, which can be triggered by several factors, one of the most common being anxiety. When an individual experiences anxiety, they may breathe more rapidly and deeply, which decreases CO2 levels in the bloodstream and resulting in respiratory alkalosis. This highlights the direct link between anxiety-induced hyperventilation and respiratory alkalosis.

Understanding the other conditions can also provide valuable context. Hypoventilation, for instance, would typically lead to respiratory acidosis because CO2 would accumulate rather than be expelled. Similarly, a respiratory infection could lead to altered ventilation patterns, but it usually does not produce the rapid breathing associated with alkalosis. Hypoxia, characterized by insufficient oxygen levels, might lead to various compensatory mechanisms, often resulting in acid-base imbalances, but in a different manner than anxiety-driven hyperventilation. Thus, anxiety is the condition most closely associated with respiratory alkalosis through its direct impact on breathing patterns.
