Question
What is the typical kOhm range that I should be looking for when preparing for an ABR?
Answer
Ideally, for disposable electrodes the impedances should be very low, from 0.5 to 3 kOhm, but at a minimum it would be best that impedances should be equal or below 5 kOhm. Reusable electrodes are expected to have higher impedances than the disposable, so you may need to aim for impedances equal or below 5 kOhms.
