4.4.1
Preparing the patient for insertion of the ear probe
General preparations of the patient
1.
Position the patient so that you can easily access the ear to be tested.
2.
Grasp the pinna and gently pull back and slightly away from the patient's head.
3.
Look into the ear canal.
If you can see apparent narrowing of the ear canal, it probably is not straight.
Because newborn ear canals are very soft, they are easily pressed out of shape. If this is the
case, wait until the ear canal returns to its original shape.
Release the pinna and try again. Gently massaging the area may help opening the ear canal.
4.
Inspect the ear canal to make sure it is clear of vernix or debris as this may affect the result
of the test.
4.4.2
Fitting the eartip on the probe
1.
Select an eartip that fits the patient's ear canal. You may have to try out a number of sizes in order to select
the appropriate size.
2.
Gently push the eartip onto the probe tip until it rests firmly against the base of the probe. It is much easier to attach
and remove the eartip if you turn it gently. When you do so, make sure that you hold the probe by the probe body
and
not by the cable
.
Caution: Make sure that you gently push the eartip onto the probe tip until it rests firmly against the base of the probe.
Note: Accurate testing is only guaranteed if you use the eartips provided.
Note: The eartip can be used for both ears. If you suspect infection in one ear, change the eartip and clean the probe tip, or
replace it with a spare, before you continue testing on the other ear.
Caution: Using a probe with an unsuitably sized eartip or applying excessive force may irritate the ear canal.
Note: In case of a probe error, make sure that the probe tip channels are clear (see
) and that
the probe is connected.
