通过对在异常仔细监测的条件下进行颈动脉血管造影的患者进行分组，已经表明低碳酸血症与低血压下的血管舒张相关，而与高血压无关。本文还讨论了其机制，认为低碳酸血症性血管舒张可能是脑缺氧的一种反应，并可能通过脑内自主神经通路传递。对50例患者进行了临床和血管造影诊断。
By grouping patients who had carotid angiograms under unusually carefully monitored conditions it has been shown that hypocapnia is associated with vasodilation at low blood pressure but not at high blood pressure. The mechanism is discussed in general terms and it is suggested that the hypocapnic vasodilation may be a response to cerebral hypoxia and may be transmitted via an intracerebral autonomic pathway. Clinical and angiographical diagnoses are given for 50 patients.
