The Puritain Bennett GoodKnight® 420G device (GK420G) is intended for treating
patients with Sleep Disordered Breathing including Obstructive Sleep Apnea Syndrome
(OSAS). The main characteristic of this pathology is the occurrence of multiple
respiratory events caused by contraction of the upper airways that disturb sleep. The
GoodKnight 420G delivers a Continuous Positive Airway Pressure (CPAP) that
prevents the upper airways from becoming obstructed thus eliminating apneas.
It is essential for you to understand the limitations on the use of this device. Therefore,
please read this manual carefully before using the GoodKnight 420G.
The information contained here is intended to help you use this device under optimum
conditions of safety and operation. For any question relating to the equipment and its
use, contact your Health Care Provider or your home Medical Equipment Provider.
Your doctor has decided on the treatment of your illness. He or she has prescribed the
various parameters that the hospital or your home care provider will program. You
must not make any adjustment, except under direct supervision of your Home Care
Provider.
CAUTION
Federal (U.S.A.) law restricts this device to sale by or on the order of a physician.

USE
This chapter shows you how to use the device 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
settings (you will not be able to alter these settings, but only view them).
WARNING
In the sections “Starting treatment” and “Stopping treatment” below, please follow the
directions carefully. If these directions are not followed, an accident can occur, especially where
the use of oxygen is concerned.
Starting treatment
Once the device has been installed in accordance with the instructions given in the previous chapter,
please follow the instructions below to start treatment:
1. Start the device by pressing the ON/OFF button.
The display shows the pressure available as well as the operation and compliance indicators (see
Figure 9).

NOTES
•
•
The pressure unit displayed (hPa or cmH2O) can be modified by the Practitioner.
The compliance operation indicator is displayed only after 15 minutes operation of the
device.
2. Put the nasal mask in place according to the instructions for its use. If a mask with exhalation
vent is used, it includes a hole by which the exhaled gases will be flushed and could not be
rebreathed. If a mask without exhalation vent is used, your doctor must provide you with an
adaptor allowing gases flushing as close as possible to the nose. Breathe normally.
WARNING
A CPAP mask with hose should not be worn unless the CPAP device is turned on and
operating properly. The vent hole(s) associated with the mask should never be blocked.
This CPAP machine is intended to be used with masks (or connectors) that have vent holes
to allow continuous flow of air out of the mask. When the CPAP device is turned on and
functioning properly, new air from the CPAP machine flushes the exhaled air out through
the mask vent hole. However, when the CPAP device is not operating, enough fresh air will
not be provided through the mask, and exhaled air may be rebreathed. Rebreathing of
exhaled air for longer than several minutes can in some circumstances lead to rebreathing
CO2 or possible suffocation. This warning applies to most models of CPAP devices.
3. If you are using a heated humidifier, turn it on according to instructions for use.
4. If you are using oxygen, open the flow now.

WARNINGS
•
•
When the device is in operation mode, check that it delivers an airflow. If no airflow is felt,
turn off the device and contact the service provider.
At lower CPAP pressures, the flow through the exhalation port may be inadequate to clear
all exhaled gas from the hose. Some rebreathing may occur.
Stopping treatment
When the GoodKnight 420G is operating, follow the instructions below to discontinue the treatment:
1. If you are using oxygen, stop the flow now.
2. Remove the interface (nasal mask).
3. If you are using a heated humidifier, turn it off according to the instructions for use. Disconnect
the humidifier from the unit.
CAUTION
Do not leave the humidifier connected to the unit or to the tubing when the humidifier is
not in use, as humidity could enter the device and degrade device performance.
4. Turn the device off by pressing the ON/OFF button. The device will return to standby mode and
display the following standby screen showing the time:
Ÿ
9:38
CAUTION
Check that no humidity appears in the tubing. If so, let the tubing dry before you use it again.
Using the ramp
First of all adjust the starting ramp pressure of your GoodKnight 420G device by observing the
following instructions:
NOTE
If the ramp time is set to zero, this adjustment is not accessible.

The pressure value can then be changed by using the ON/OFF and Ramp keys.
The ramp function enables you to make the rise in pressure progressive. Thus, the pressure level is
low at the start of the night to help you to fall asleep. You can also use this function if you have to
get up during the night and have difficulty going back to sleep. The pressure rise time up to the final
pressure is prescribed by your medical team and the setting carried out by your service provider is
between 0 (no progressive rise) and 30 minutes in 5-minute increments. The ramp may have been
preset to 0 according to your medical team’s prescription. In this case, the ramp function is disabled
and pressing the Ramp button on the front panel of the device has no effect. (Refer to reference 3 in
Figure 2, page 5).
1. To start the ramp, just press the Ramp button when the device is on. The pressure will fall to a
lower value, as previously described, then increase progressively up to the prescribed pressure
level, so as not to wake you. The device will run normally, delivering a treatment pressure
throughout the night unless you press the Ramp button again.
2. To end the ramp, press the Ramp button again and the function will be disabled. To reset the
