An Extraordinary AEP Product

by Greg Ollick, Sr., M.A.


"We brought the new Integrity Gen 2 device into environments loaded with electro- magnetic interference which is very hostile to AEP testing, and the Gen 2 system was virtually unaffected....We were able to get clear, clean ABR and ECocGh responses with the patient awake, sitting up and occasionally talking, and we obtained all of this in substantially less time than with any other system."

Non-Sedated ABR

Minimize the risks and cost of sedation


An auditory brainstem response (ABR) assessment is valuable for estimating hearing thresholds of infants and young children, and for assessing suspected retrocochlear auditory dysfunction. A considerable disadvantage, however, is the use of sedation and/or anesthesia to minimize muscular activity which contaminates ABR recordings. Typically, infants, young children, and special needs adults have required sedation and/or anesthesia in order to obtain reliable ABR recordings.


The VivosonicTM Integrity V500 System is a unique wireless ABR system with technological advancements that make sedation and anesthesia an unnecessary requirement. This innovative technology improves patient care while providing superior response detection, clinical efficiency, and substantial cost savings of $5000 USD per test by avoiding anesthesia and sedation. Clinical evidence from Hall and Sauter (2010) confirms that ABR without sedation is a viable, practical, and cost-effective alternative to conventional ABR practices that use sedation. Furthermore, clinical experiences with Vivosonic non-sedated ABR indicate that clinical effectiveness and efficiency can be significantly improved by this approach.


Sedation and anaesthesia are associated with medical risks1,2 to patients, parental concern, scheduling delays, increased time and costs and specialized resource demands. Although interest in a safe and effective alternative is increasing, a report by the Pediatric Sedation Research Consortium identified ABR measurement as a procedure for which sedation is still commonly used.3 The report further revealed that monitoring guidelines published by the American Academy of Pediatrics (AAP), to ensure patient safety, were followed in only 52% of 114,855 cases of pediatric sedations. This lack of monitoring poses obvious risks to patients undergoing ABR under sedation.


A study by Cone et al. (2013) investigated innovations in the electrophysiological assessment of infant hearing. Cost modeling based on the findings conservatively estimated cost savings of $300 USD per day by using the innovative technologies of the Vivosonic IntegrityTM System, and a savings of $5,000 USD per patient by avoiding anesthesia and sedation.
