ABR test procedure
10.2 Checkt
The test stimulus in ABR tests can be provided either by inserting the
probe into the ear, as for OAE testing, or by applying an ear cup to the
ear and inserting the probe into the ear cup. Ear cups can be particularly
useful in neonates with very small ear canals where a secure probe t is
not possible. They can also be useful in preventing the probe from being
dislodged by movement during testing.
If ear cups are not in use then Checkt proceeds as for OAE tests (see
section
7.2 for details).
Checkt with ear cups is described below.
10.3 Ear cup Checkt
To test with ear cups, the Ear Cup mode in ABR Other Settings must
be set to Auto or On. The T7M tip (UGS probes) or the R7M tip (UGD
probes) should be used to secure the probe to the ear cup. See section
15.2.4 for more details.
Ear Cup mode set to Auto
In Checkt, the device will check whether ear cups are being used by
checking if a large cavity has been detected. If this is the case, then the
user will be prompted with a message to conrm. There will be three
options: Yes, No and Checkt. Using the probe direct in a neonate ear will
always create a small cavity, but using large (adult) ears may trigger the
prompt.
If No is selected, the device will go into normal Checkt.
