Diaphragmatic breathing is recommended for patients experiencing acute hyperventilation because it encourages the use of the diaphragm rather than the accessory muscles of breathing, which are often overactive during episodes of hyperventilation. This technique promotes slower, deeper breaths, which can help to normalize the respiratory rate and improve gas exchange. By engaging the diaphragm, patients can reduce feelings of anxiety and improve their ability to manage their breathing pattern. This method is effective in countering the rapid, shallow breaths characteristic of hyperventilation by helping to stabilize the respiratory rate and enhance overall oxygenation.

In cases of hyperventilation, techniques like pursed lip breathing may also be effective, as they can help to control airflow and increase carbon dioxide retention. However, diaphragmatic breathing specifically addresses the underlying physiology of hyperventilation more effectively.

Controlled breathing is a broader term that encompasses various techniques, and while it can be beneficial, it does not specifically highlight the emphasis on using the diaphragm and regulating breath patterns as prominently as diaphragmatic breathing does. Belly breathing is a term often used interchangeably with diaphragmatic breathing, yet it can be less specific in guiding patients through the exact technique needed to alleviate hyperventilation symptoms.
