5.3
Fitting the probe in the patient's ear
1. Look into the ear canal. It is strongly recommended that you perform an otoscopy to assess the status of the outer ear
before you insert the probe.
2. If the ear canal is blocked, this may affect the result of the test. Clean the ear canal if needed.
Caution
•
The probe can be damaged if fluids enter the probe.
Warning
•
Never place the probe tip in the ear canal of a new patient without using a clean eartip.
Warning
•
The eartip can be used for both ears. If you suspect infection in one ear, use a clean eartip and probe tip
before you continue testing on the other ear.
Caution
•
Always use a suitably sized eartip. Using a probe with an unsuitably sized eartip or applying excessive force
may cause unnecessary discomfort to the patient.
Procedure
1. Fit the eartip on the probe.
2. To stabilize the probe and to avoid blocking the probe against the ear canal of the patient, grasp the pinna and gently
pull the pinna back and slightly away from the patient's head.
–
For adults: pull the pinna upwards and back.
–
For infants and children: pull the pinna downwards and back.
3. Insert the probe in the patient's ear canal while twisting the probe gently.
4. Make sure that the eartip fits well. This will minimize the risk of blocking the probe tip against the ear canal wall.
Probe status and leakage
The status indicator in the lower left corner of the device screen, or, if applicable, on the AudioConsole screen, will show
the status of the probe.

Description
Blocked

the ear).
Leak
Indicates that the air seal between the probe and the ear is not tight.
