Warning
•
Always fit the probe with a new eartip when you place the probe in the ear canal of a new patient.
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
•
Avoid excessive force when you place the ear tip against the ear canal opening of the patient as this may
cause unnecessary discomfort, particularly if the eartip is small enough to enter the ear canal.
Fit the probe in the ear
1. With a hand-held probe you can use a slightly over-
sized eartip in order to achieve a seal when used
with a wider range of ear canal sizes.
The oversized eartip is not intended to enter the
ear canal.
2. Fit the eartip on the probe.
3. Ask the patient to sit very still and quiet during
the test, without moving head or jaw.
4. Press the probe against the patient's ear canal so
that a hermetic seal is achieved. The meas-
urement starts automatically.
5. 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 down-
wards and back.
Quick Check probe placement
6. A flat tympanogram together with an abnormally
small ear canal volume (ECV) indicates that the
probe is blocked
7. Any leakage will interrupt the test. The probe will
indicate if there is a leak.
When you get a leak detection signal, you must
briefly remove the probe from the ear before try-
ing again.
