Transcript DESIGNING THE INFANT HEARING PROGRAM

INFANT HEARING PROGRAM:
Introducing the AccuScreen In-service
Spring 2015
ACCUSCREEN – Getting Started
• The AccuScreen is a touchscreen unit that has the
capability to screen using Automated Distortion
Product Otoacoustic Emissions (ADPOAE) or
Automated Auditory Brainstem Response (AABR)
or both, depending what the configuration is.
• The AccuScreen is a hand-held, battery powered
unit that can be charged in the docking station.
The battery will be fully charged after six hours.
A full charged battery will last eight hours,
depending on use.
ACCUSCREEN – Getting Started
Caring for the equipment
• What pieces are disposable?
• What is the easiest way to maintain equipment?
• Can we prevent breaks?
-Hold equipment carefully, to avoid dropping it.
-Keep wires tidy, avoid knots.
-Insert connections into the correct ports.
ACCUSCREEN – Getting Started
• To turn it ‘on’ press the grey button on
the side of the unit, press and hold the
bottom of the button to turn it ‘off’.
Probe Test
Battery
release
• To remove the
battery (reboot or
change battery)
press the battery
release and the
back will open.
• To self calibrate insert the probe
into the back of the unit.

ACCUSCREEN – Getting Started
Home page
• Find a Patient
• Create a New Patient
• View the Tests
• Print the Tests
• Delete Patients
• Quick Test to check your hearing
• Quality test to troubleshoot
• Settings to change i.e. date, time, log in
ACCUSCREEN – New Patient
• We do not store personal health information without encryption. Select
New Patient to get a new ID and perform the test.
ACCUSCREEN – New Patient
• To enter a numerical ID touch ‘123’ to switch from ‘aaa’. Touch the
checkmark after you entered the desired number.
ACCUSCREEN - Probe Tips and Eartips
• There are five disposable eartips available
for use with infants; 3.7mm yellow, 4.0mm
green, 4.5mm pink, 5.0mm blue and the
transparent tree tip 4-7mm.
• A clean eartip must always be used when
placing the probe tip into the ear canal.

Probe Tip
ACCUSCREEN – Connecting the probe tip
• Click the probe tip onto the speaker cable, then slide the appropriate
sized eartip on.
• To remove hold the probe tip at the top and bottom along the groves,
push together then outward.
IHP – Stage One Screening
Babies NOT at Risk
• A two step process.
• Step one with ADPOAE equipment.
• Step two if needed with AABR equipment.
• Step two should be done as soon as possible
to reduce parental anxiety.
IHP – Stage One Screening
• DPOAEs are generated by the outer
hair cells (OHCs) of the cochlea.
• Normal DPOAEs usually mean that
hearing is normal (at the time of
screening…)
• Absent DPOAEs suggest that
hearing may be abnormal and
further testing is needed.
IHP – Stage One Screening
Infants will either receive a pass or a refer result.
• A pass means that the baby is hearing at this time.
But, it is always important to monitor.
• A refer does not necessarily mean that the
infant has a hearing loss. Commonly,
debris in the ear canal, fluid in the
middle-ear or movements during the
test will affect results. A referral to
another stage of screening is needed.
ACCUSCREEN – ADPOAE
• The hearing screening is a quick, easy,
non-invasive screening test that does
not involve the performance of any of the
controlled acts under the Regulated
Health Professions Act, 1991.
• Provision of parental consent is required,
unless hearing screening is performed as
part of a hospital’s standard of care.
• Consent to share results with the
regional IHP is always required.
ACCUSCREEN – ADPOAE
• To screen with the ADPOAE connect the
cable with the blue base.
• Ensure the arrows are aligned properly.
• Select an appropriate eartip.
• Put on the probe tip and eartip.
• Select the ear for initial screen.
ACCUSCREEN – ADPOAE
• Touch the black arrow to begin. The equipment will calibrate and then
initiate screen. The screen is completed once three frequencies have a
clear response.
ACCUSCREEN – ADPOAE
• The Test Menu has tests completed and test results. The Test View
shows all attempts including missed calibrations and aborted tests.
ACCUSCREEN – DPOAE Errors
• If there is too much noise, reduce environmental noise i.e. turn off cell
phones and/or check the ear for debris. You can also try a Quality Test
to make sure the probe is OK.
ACCUSCREEN – AABR
• Soft sounds are played in the
baby’s ear and the brain’s
electrical response is recorded
using three sensors (electrodes).
• The brain’s response to the
sounds is automatically
analyzed and interpreted by the
AccuScreen.
ACCUSCREEN – AABR
• To conduct an AABR, connect both the green
and blue cords.
• Make sure the arrows are aligned properly.
• The red electrode goes on the right mastoid.
• The black electrode goes on the left mastoid.
• The white electrode is placed on the baby’s
forehead (high midline).
ACCUSCREEN – AABR
• Touch the black arrow in the Test Menu. Once impedance values are OK,
the black arrow is highlighted, touch to start. The testing page will appear.
The test is complete when the ABR bar or Progress bar is full.
ACCUSCREEN – AABR Errors
• If impedance values are good, the color will be green. Yellow means that
the connection is not as good. Red is unacceptable. A yellow reading can
turn red if the electrode is loose or falls off.
ACCUSCREEN – Troubleshooting
Quality Test
• Before testing babies each day, a Probe Test should be
done. Insert the probe into the test cavity at the back of
the AccuScreen. The test will start automatically.
• Results will appear as ‘Probe OK’ or
as ‘Probe failed’ with possible errors.
ACCUSCREEN – Troubleshooting
Loose Cord Error
• If your electrodes appear attached but
you still get poor impedance or loose
cord errors, perform an Electrode
Test to check the cables.
• Attach the electrode cable wires and
check with a Quality Test to make sure
they give good impedance.
• The Test results page will indicate the
condition of the electrode cables.
ACCUSCREEN – Troubleshooting
Other Errors and Solutions
• AABR does not start – press the triangle to start.
• Black screen – unit powered off (eject battery if needed).
• Timeout during pause – AABR was paused more than two minutes.
