脑电阻图亦称脑血流图,用于测定颅内血液搏动性流动而引起的阻抗变化,借以反映大脑血管功能状态的一种无损伤的检查。由于设备简单,操作方便,反映客观,且可连续观察,因此,在临床上已广泛应用多年;近年来,预防医学方面应用脑电阻图观察接触各种职业性危害因素对大脑血管的影响。为了探索脑电阻图在职业体检和劳动卫生调查中的应用价值,我们测定了正常人、铅、苯、高频
Brain electrical resistance map, also known as cerebral blood flow diagram, is used to measure changes in impedance caused by intracranial blood flow to reflect non-invasive examination of the functional status of cerebral blood vessels. Because of its simple equipment, easy operation, objective reflection, and continuous observation, it has been widely used in clinical practice for many years. In recent years, preventive medicine has been used to observe the effect of exposure to various occupational hazards on cerebral blood vessels. In order to explore the value of the brain resistance map in occupational health examinations and occupational health surveys, we measured normal, lead, benzene, high frequency
