Auditory Evoked Potentials with the GSI Audera Pro

Please note: exam questions are subject to change.

1. Prior to utilizing a new ABR system, careful review of test protocols is recommended. Important parameters to review are: Amplifier gain and filter settings. Modulation rate L1 and L2 F1 and F2
2. Cross correlation is Only used during ASSR testing Performed during active waveform collection A way to compare 2 ABR protocols A measure of the similarity between two waveforms or areas of waveforms.
3. Compare 2 Selected Recordings will Calculate and display the cross-correlation value Only helpful with DPOAE testing Calculate and display the difference in Wave V latency between ears Create a grand average waveform
4. The ABR CPT code 92651 is defined as “ABR for hearing status determination, broadband stim only; with interpretation and report.” An example of a broadband stimulus is The speech sound ‘da’ CE Chirp and click Frequency modulated pure tone Amplitude modulated pure tone
5. The new CPT code defined as “ABR for threshold estimation at multiple frequencies; with interpretation and report” is 92652 92557 92585 92700
