7 Preparing for testing
In order for you to save time for both you and the client, we recommend that you prepare the environment, the client,
the test device setup and the OTOsuite software so that they are ready for the test.
To prepare for testing:
•
If this is the first test of the day, make a probe check. See

.
• If needed, connect the contralateral phone. See The contralateral phone ► 26 .
• Prepare MADSEN Zodiac and the Immittance module: select the patient and test setup. See the OTOsuite User Guide.
• Prepare the patient. See Inspecting the patient’s ear ► 38 .
• Prepare probe and eartip. See

7.1 Preparing the test environment
Immittance tests require no specific test environment with regard to noise.
7.2 Hygienic precautions
• Be sure to follow any established infection control procedures for the setting in which you are working.
• Always use clean eartips.
• Swab the probe tip with disinfectant between ears. If one ear is infected, test the healthy ear first and change eartips
between ears.
• To prevent cross-infection, use a clean eartip when you test the next patient.
7.3 Probe check
To make sure that the probe is functioning correctly, it is recommended that you perform a probe check at the start of
each day.
Caution
•
Always clean and disinfect the probe tip before you insert it into a test cavity.
See Cleaning the probe and probe tip ► 120 .
Note
•
If the test environment changes, for instance if there is an increase in humidity or if you are going to test
at a different altitude, make a probe check to verify that the system measures correctly.
Note
•
If the probe check result does not show a value of 1.9 - 2.1 mmho/cc/ml at 226 Hz, we recommend that
you make an admittance calibration. See Probe admittance calibration
