In 20 patients with expanding intracranial lesions the cerebral blood flow was determined by the method of Kety-Schmidt in an own modification with an original device--N2O-meter, with simultaneous continuous measurement of the intraventricular pressure and arterial blood pressure. This made possible determination of the cerebral perfusion pressure and of the effect of its fluctuations on the cerebral blood flow. Lowering of the cerebral blood flow below the normal value occurred when the perfusion pressure fell below 60 mm Hg, but its further fall, even to 20 mm Hg, caused no proportional decrease of the cerebral blood flow.
在20例颅内病变不断扩大的患者中，采用凯蒂-施密特法的一种自行改良方法，使用原装设备——氧化亚氮测定仪，同时连续测量脑室内压力和动脉血压，以此测定脑血流量。这使得测定脑灌注压及其波动对脑血流量的影响成为可能。当灌注压降至60毫米汞柱以下时，脑血流量会降至正常值以下，但其进一步下降，即使降至20毫米汞柱，也不会导致脑血流量成比例减少。
