引言：

尽管不存在一个适用于所有情况下记录脑电图的最佳方法，但下列标准被认为是除小儿（见指南2：小儿脑电图最低技术标准）外的各年龄组临床记录脑电图的最低要求。最低标准下的记录不会使脑电图人员满足，也不能确保检测满意。最低标准仅仅是确保对患者和相关医生履行一定的责任。特别推荐最低标准是为了改善操作的标准化，也是为了促进北美各实验室之间记录和判定的交流。更多细节详见国际临床神经电生理联盟的相关文献。

1．设备

1.1 在尽可能多的头皮同步记录，对于发现脑电活动是必须的。同步记录的导联太少，解释发生错误的机会就增加，相对地，使用越多导联，这种错误发生的可能性就会减少。对于短暂性的活动这点尤为突出。要显示大多正常和异常脑电图波形，至少需要16导联的记录。有些生理活动检测需要更多导联。

1.2 交流电线路应该符合保险公司对于医院设备需要遵循的实验室标准。所有交流电插座必须提供合适的接地设施。在脑电图室，患者每一个部位的所有设备必须在一个公共接地点。

1.3 一般的诊室环境，在患者和设备间不必设屏蔽，除非证明有必要。

1.4 辅助设备应包括能对患者发出高频闪光刺激的装置。

1.5 数码设备应符合指南8的要求。

附英文原文

1.Equipment

1.1 To find the distribution of EEG activity, it is necessary to record simultaneously from as many regions of the scalp as possible. When too few channels are used simultaneously, the chances of interpretive errors increase, and, conversely, when more channels are utilized, the likelihood of such errors decreases. This is particularly true for transient activity.

Sixteen channels of simultaneous recording are now considered the minimum number required to show the areas producing most normal and abnormal EEG patterns. Additional channels are often needed for monitoring other physiologic activities.

1.2 Alternating current (AC) wiring should meet the Underwriters Laboratories standards required for hospital service. Adequate grounding of the instrument must be provided by all AC receptacles. All equipment in each patient area in the EEG laboratory must be grounded to a common point.

1.3 In the usual clinical setting, electrical shielding of the patient and equipment is not necessary, and such shielding need not be installed unless proven necessary.

1.4 Ancillary equipment should include a device for delivering rhythmic, high-intensity flash stimuli to the patient.

1.5 Digital equipment should conform with the recommendations in Guideline 8.
