CHARTR EP with PediABR is designed to provide fast assessment of hearing in babies. The instrument provides default linked protocols for infant testing, including Pediscreen, PediTone and PediBone protocols. It plots toneburst thresholds on the PediGram, a graph similar to an audiogram and features a continuous stimulation to prevent disturbances to the baby during testing. CHARTR EP with PediABR can be combined with ICS Medical’s CHARTR OAE which provides screening and diagnostic OAE capabilities.
CHARTR OAE runs under the NOAH database and can be used for both screening and diagnostic testing. It uses a Windows-based platform and offers a menu of testing options including “pass” and “refer” OAE screening, transient evoked OAE’s and distortion product OAE’s.
CHARTR EP with PediABR combined with CHARTR OAE is the only integrated system offering all the pediatric tests needed to evaluate hearing loss in infants, according to the company. This combined testing protocol can be used to follow-up infants who fail initial screening tests.
