Interacoustics OtoRead - Indicators, System Checks, and Patient Preparation

OtoRead Screener Operating Instructions Page 23
The results will be saved even if the unit turns off or the
batteries are temporarily removed. This screen again indicates
the test ear and further gives the results of the test. “Pass” on
the screen indicates the patient passed the screening,
“REFER” indicates that the patient did not pass the screening.
“NOISY” indicates that excessive noise was present during the
test. ”NO SEAL” indicates that a seal was not maintained
throughout the test.
“FIT ERR” indicates inadequate probe placement in the ear
canal to produce target stimulus intensities. When the test
result is “Noisy”, “No Seal”, or “FIT ERR” the tester should
reposition the probe, selecting a different size eartip if
necessary, and retest. If the test result is “REFER” the tester
can determine from the printout whether the test should be
repeated. To review the results, push the DOWN arrow key to
return to the bar graphs.
After reviewing the results, again push the DOWN arrow key
to return to the Main Menu. Once a new test for that ear is
started, the previous results are erased. By default, the
OtoRead instrument will save only the last test for each
ear. When testing is completed, the results should be
printed before a new patient is tested. Note, however, that
the OtoRead instrument can be configured to store up to 250
tests in the unit for printing at a later time. It is important to
keep a record of the test number for each patient if this feature
is used. See Save Mode/Storing Test Results on page 30 to
set up the device to save 250 tests in memory.
Test Technique
As with other otoacoustic emission test instruments, there is a
technique to learn when using the OtoRead instrument,
especially for newborns and infants. Experience with existing
OAE systems suggests that it may take up to 3 months to
become completely proficient at screening newborns. When
testing a newborn or infant with the OtoRead instrument, the
following suggestions might be helpful: The newborn has to be
relatively quiet and calm; it is usually preferred for the infant to
be asleep. A pacifier may be used to calm the newborn;
