[Feasibility analysis of new dry electrode EEG sleep monitoring]

Objective:To evaluate the accuracy of the new carbon black polyurethane dry electrode electroencephalogram and clarify the value of the new dry electrode electroencephalogram. Method:Forty-three male-adult patients in the group were wearing both Ag/AgCl wet electrode and new dry electrode for sleep monitoring. The wet electrode recording was used as the gold standard for diagnostic accuracy analysis of dry electrode monitoring results. Result:The overall accuracy of the new type of dry electrode EEG was 74.53%, and the diagnostic efficiency of the dry electrode was significantly different among different stages. The sensitivity of WK, N1, N2, N3 and REM is 85.75%, 61.92%, 74.22%, 79.70% and 74.50%, and the specificity is 95.54%, 88.46%, 88.15%, 95.07%, 98.55%, respectively. Conclusion:The dry electrode EEG acquisition accuracy is good, especially for the WK, which is beneficial to improve the accuracy of the portable sleep monitoring equipment for the diagnosis of OSA disease.
