Sera™

Prepare the equipment

  1. Turn on SeraTM by pressing the home/power button
  2. Select a new or existing patient on the device or use the Quick Test option.
  3. Select the TEOAE test protocol from the list.
  4. Select the ear for testing
  5. Pressing the Test button  starts the test.

Test environment
The ideal test environment for OAE testing is a quiet room. Loud ambient background noise adversely affects OAE measurements.

Prepare the baby
The baby should be sleeping or in a quiet and relaxed state. Sucking, blinking, crying or movement may affect testing.

Place transducer
Place an ear tip onto the probe tip and place the probe in the ear. Avoid holding onto the probe during the measurement as this can produce noise that may affect the test result.

Run test
Press the Test button 

Results

PASS result   REFER result  

INCOMPLETE result

         
When the pass criteria for the test is reached, a  is displayed in green above the measurement, indicating the test has PASSED.  

When the pass criteria for the test is not reached within the measurement time,  is displayed in amber above the measurement, indicating the test is a REFER.

  If the test is stopped before a PASS or REFER is generated by the system,  is displayed above the measurement indicating that the test is INCOMPLETE.

Prepare the equipment

  1. Turn on SeraTM by pressing the home/power button
  2. Select a new or existing patient on the device or use the Quick Test option.
  3. Select the ABR test protocol from the list.
  4. Select the ear for testing
  5. Pressing the Test button  starts the test.

Test environment
The ideal test environment is a quiet room where lights and other electronic equipment are turned off.

Prepare the baby

Patient state

The baby should be sleeping or in a quiet and relaxed state. Sucking, blinking, crying or movement may affect testing.

Skin preparation

If the baby’s skin is oily or covered in vernix, the electrode placement sites should be cleaned prior to placing the electrodes.
Use a conductive gel with the electrodes to improve impedances.

Place electrodes

Place surface electrodes using the specified test montage for the selected protocol (mastoid or nape).

Connect cables

Connect the cables from the preamplifier to the respective surface electrodes.

Place transducer
Place the probe or inset earphones in the baby’s ear/s or place the EarCups around the baby’s ears.

Run test
Press the Test button 

Impedance check 
An impedance check will begin. Impedances are indicated by the green/amber dots on the montage picture as well as in numerical format on the screen.

When a dot is amber, it means the impedance is poor (> 40kΩ) for the indicated electrode. Check that the surface electrode and cables are connected correctly. It may be necessary to re-clean the skin or use a conductive gel with the surface electrodes to achieve an acceptable impedance. Testing cannot begin until impedance indictors are green (< 40kΩ).

Results

INCOMPLETE result

         
When the pass criteria for the test is reached, a  is displayed in green above the measurement, indicating the test has PASSED.  

When the pass criteria for the test is not reached within the measurement time,  is displayed in amber above the measurement, indicating the test is a REFER.

About this quick guide

This quick guide provides instructions about how to place and attach the Sera™ and accessories on the cart. Follow the cart manufacturer’s instructions to assemble the cart prior to installing the Sera™ and accessories.

Installing the cradle

  1. Set the cradle on the cart with the front under the fall prevention plate.
  2. Pass the cradle power supply cable through the pass-through hole and connect it to the port on the back of the cradle.
  3. Attach the stabilizer plate over the cradle’s metal bar and fasten with screws.
  4. Plug the power supply into a power strip1 securing the cables with the post cable clips and tie wraps to create a neat appearance and prevent rolling over the cords during transport.

1  The power strip is not included with the cart. The customer must supply an appropriate power strip that meets local standards and has at least 2 outlets that can accommodate the plugs of the printer and cradle.


Installing the cables

  1. For storage/transport, place the preamplifier, electrode cables and transducers as shown.
  2. For storage/transport, place the probe as shown.
  3. For storage/transport, set the plug of power strip into the edge pocket as shown securing any hanging cables in attached bin to prevent rolling over the cord.

Installing the printer

  1. Attach custom plate with the pictured 5/16-18 screws to the printer.
  2. Insert the printer with the custom plate attached into the recess and fasten with the knob.
  3. Pass the printer power supply cable through the pass-through hole behind the printer and connect it to the charger port on the right side of the printer.
  4. Plug the power supply into the power strip securing the cables with the post cable clips and tie wraps to create a neat appearance and prevent rolling over the cords during transport.
