Preparing for Testing Echo-Screen III Pro Instructions for Use
Apply the electrodes for ABR screenings:
1 If the patient's skin is dry or oily, prepare the skin for the electrodes by using saline or
NuPrep
®
gel. Skin preparation reduces electrical impedance, allowing for better
conductivity of the ABR electrical signals.
• Oily skin responds well when cleaned with mild soap and water, followed by an
application of NuPrep
®
gel (gel for neonates).
• Dry skin responds well to an application of saline or NuPrep
®
gel, or a drop of saline
under each electrode.
Note: Alcohol dries the skin. If alcohol use is permitted, follow it with a wet
gauze wash or apply NuPrep gel to rehydrate the skin.
IMPORTANT: If the electrodes appear discolored or hard, or are not sticky when removed from
the foil pouch, dispose of the electrodes and use new ones. Do not use damaged or expired
electrodes.
2 Attach the clips of the PCA cable to a triplet of disposable Jelly Tab electrodes: Squeeze
each clip open and place it on the tab of the electrode. Keep the cable side of the clip and
the gel side of the electrode on the same side. Attach the clips to the electrodes before
removing the electrodes from the adhesive liner card.
3 Hold the electrodes by the tabs. One at a time remove the liner card from each electrode
and attach the electrode to the patient, orienting all the electrodes in the same general
direction:
• Black clip: Vertex (center forehead, as high as possible, nearest to the hairline and
away from eyebrow and eye area. Avoid the forehead muscles to increase screening
efficiency.)
• White clip: Nape (centered on back of the neck, not on the skull or back.)
• Green clip: Common (back of either shoulder, not touching the nape sensor.)
IMPORTANT: Failure to place electrodes in the recommended locations can result in
significantly slower screening and increased Refer rates.
WARNING

Do not use soap or alcohol on an infant’s skin unless permitted by your facility’s
standard protocol.

Do not prepare skin or apply electrodes to damaged or compromised tissue or to
babies with marked jaundice.

Do not leave electrodes on a baby for prolonged periods. If the baby perspires under
an electrode that has not been removed, irritation may develop.
CAUTION Connect the PCA cable clips only to the purple colored tab section of the electrode. Do
not allow the PCA clip to come in contact with the hydrogel portion of the electrode.
Myogenic readings may be affected.
