Preparing for testing
To save time for both you and the client, 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, perform a probe check. See
Probe check 32
.
•
If needed, connect the contralateral phone. See
The contralateral phone 23
.
•
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 34
.
•
Prepare probe and eartip. See
Fitting the eartip on the probe 34
and
Fitting the probe in the patient’s ear 35
.
7.1
Preparing the test environment
Immittance tests require no specific test environment about noise.
7.2
Health 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 perform a probe check at the start of each day.
See
Cleaning the probe and probe tip 115
.
If the test environment changes, for instance if there is an increase in humidity or altitude, perform a probe check to
verify that the system measures correctly.
1.
Use a new probe tip, or clean and disinfect the probe tip before you place it in the test cavity. Clean the probe tip to
make sure the probe tip does not influence the probe test, and the test cavity is not contaminated.
2.
Insert the probe tip without eartip in the 2-cc test cavity.
3.
Select the probe check function:
