Thirty patients who were considered to have the hyperventilation syndrome on clinical grounds (history and observation) were referred for testing: 29 patients completed a forced hyperventilation provocation test, and 28 underwent hypnosis during which time a psychological challenge was introduced which was meaningful to each individual patient. In 19/27 of these patients the PetCO2 fell by an average of 18.2 mmHg and persisted spontaneously for more than three minutes. In 10 normal controls studied in a similar fashion there was an average fall of 5 mmHg. The difference in response between responders and controls/non-responders was highly significant (P less than 0.001). A review of the literature is presented for comparison. It is considered that a psychological challenge under hypnosis may have important implications for diagnosis and therapy in some patients considered to have the hyperventilation syndrome.
根据临床依据（病史和观察）被认为患有过度通气综合征的30名患者被转诊进行检测：29名患者完成了强迫性过度通气激发试验，28名患者接受了催眠，在此期间引入了对每位患者都有意义的心理挑战。在这些患者中的19/27中，呼气末二氧化碳分压（PetCO2）平均下降了18.2 mmHg，并自发持续超过三分钟。以类似方式研究的10名正常对照者平均下降了5 mmHg。反应者与对照者/无反应者之间的反应差异非常显著（P小于0.001）。为作比较，对文献进行了综述。认为催眠状态下的心理挑战可能对一些被认为患有过度通气综合征的患者的诊断和治疗具有重要意义。
