USING THE GOODKNIGHT 425
This chapter shows you how to use the GoodKnight 425 after installing it as described in the previous
chapter. It also shows you how to use the pressure increase (ramp) function and how to access
information on device settings.
NOTE
You will not be able to alter the device’s settings; you can only view them.
WARNING
In the sections “Starting Treatment” and “Stopping Treatment” below, carefully follow the order
given. Failure to do so could increase the potential for fire in cases where oxygen is used. Refer to
the general warning on using oxygen on page 1.
Starting Treatment
Once the device has been installed, follow the instructions below to start treatment:
1. Start the device by pressing the ON/OFF button .
The display shows the pressure measured as well as the operation and compliance indicators (see
Figure 9).

NOTES
• The units of measure displayed for pressure (hPa or cmH
2
O) can be modified by the
Practitioner.
• The compliance operation indicator is not displayed until the device has been operating for
at least 15 minutes.
2. Put the patient interface (nasal mask) in place according to its instructions for use. If an interface
with an exhalation vent is used, it includes a hole by which the exhaled gases will be flushed out,
preventing them from being rebreathed. If an interface without an exhalation vent is used, your
doctor must provide you with a
Pirouette
™
silent leak or equivalent adapter, allowing gases to be
flushed out as close as possible to the nose.
NOTE
When using this device, always remember to breathe normally for best results.
WARNING
The vent hole associated with the interface should never be blocked. This CPAP device is
intended for use with interfaces (or connectors) that have vent holes to allow a continuous
flow of air out of the interface. When the CPAP device is turned on and is operating properly,
fresh air from the CPAP device flushes the exhaled air out through the interface vent hole.
However, when the CPAP device is not functioning, adequate fresh air will not be provided
through the interface, and exhaled air may be rebreathed. Rebreathing exhaled air for longer
than several minutes could, in some circumstances, lead to suffocation.
