7、nimum Requirements for PolygraphInstrumentation and Software5.1 A minimum of two channels of respiratory activity shallbe simultaneously recorded, one thoracic and one abdominal.5.1.1 A minimum of one channel of exosomatic electroder-mal activity, via resistance or conductance, shall be recorded.5.1
8、.2 A minimum of one channel of cardiovascular activityshall be recorded.5.1.3 Additional channels may be recorded but shall not beused in place of respiration, electrodermal and cardiovascularactivity.5.1.4 The instrumentation and software shall allow a way tomark the recorded information with the f
