title: Influence of electrode impedance on auditory brain stem response recordings in the intensive care nursery.
abstract: ABR results from 400 newborns were examined for skin contact-electrode impedance effects on screening results. Neither high electrode impedance nor unbalanced impedance between the active electrodes appeared to have a significant effect on the screening results. Caution is advised in interpreting the results of this study. The authors are not advocating poor skin-electrode contact. However, satisfactory responses have been recorded with higher than previously reported optimal electrode impedance.
