Checking the Components
In order to use the GoodKnight 425, you must have the following items:
•
A breathing circuit
•
A non-invasive patient interface (mask), and all related accessories as specified in the instructions
for using it.
In addition to these accessories, your doctor may have prescribed the use of a humidifier. If so, check
that you have all the accessories required for the humidifier specified in the operating instructions.
If supplemental oxygen is required, you will also need an adapter (unless the oxygen supply connects
directly onto the interface). See the section titled “Fitting an Oxygen Adapter” on page 8 of this
manual.
Carefully check the device and each accessory. Check especially the tubings for damage. The interface
should not have any cracks or distortion in the mask or pillows (the part of the mask coming in contact
with the face).
Carefully check the device and the specific power supply module and verify that there is no obvious
fault. Plug the device into the power outlet using the power supply module, referring to steps 4 and 5
of the section entitled “Standard Installation” on page 7.
The device type is displayed temporarily,
then the following standby screen appears that displays the
time in the 24-hour format (the value displayed is given as an example only):
10:34 Ÿ

If the device is disconnected and then power restored, the screen displays the pressure. The device’s
pressure settings remain the same as those used when the power supply cord was disconnected.

You should hear the turbine start and increase speed to deliver the set pressure.
Stop the device by pressing the ON/OFF button
and unplug the power supply cord from the
power outlet.
WARNING
