## What is MedRx iVRA?

Visual Reinforced Audiometry is a test designed for pediatrics when the child is too young for normal pure tone testing. This test is typically performed with children 6 months to 2-3 years of age. The iVRA system utilizes cartoon videos reward system to help determine responses from the child. 

General Use:

Swipe right to display a reward (must present a tone and be within response window(s) to display reward)
Swipe up to increase level
Swipe down to decrease level

Conditioning Mode: The conditioning mode allows you to present rewards without linking to a presentation stimulus. This is designed to allow a tester to condition the child to receiving visual rewards in preparation for the test procedure. No data is stored from conditioning mode.

Manual Mode: The manual mode will allow for manual testing. You can choose level, frequency and ear in which you to present tones. Catch trial are still present in manual mode. Double tap the number to save a threshold. All data presented will store inside of the Studio log files when saving data. You must save the data for the thresholds to transfer into Studio. 

Automatic Mode: The automatic mode will allow for automatic testing. In this mode, you can select frequency and starting level. Once you present a tone for a frequency, the level will be adjusted automatically until threshold is determined for the frequency. Continue with next frequency until all desired testing is completed. All data presented will store inside of the Studio log files when saving data. You must save the data for the thresholds to transfer into Studio.
