Twenty panic disorder patients underwent a 35% CO2 challenge test and a hyperventilation provocation test. CO2-induced anxiety proved to correlate significantly with respiratory symptoms. These symptoms appeared to be considerably more severe during CO2 inhalation than during the hyperventilation provocation test, which induced no significant anxiety.
20名惊恐障碍患者接受了35%二氧化碳激发试验和过度通气激发试验。结果表明,二氧化碳诱发的焦虑与呼吸症状显著相关。这些症状在吸入二氧化碳期间似乎比在过度通气激发试验期间严重得多,后者并未诱发明显的焦虑。
