ii GoodKnight 420G - Patient Manual
Revision C
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.

Revision A
Checking the components
In order to be able to use the GoodKnight 420G with its specific electrical power supply, you must
have at least the following items:
• A patient tubing.
• A nasal mask (often called an “ interface ”) with all its fastening accessories as specified in the
instructions for using this mask.
In addition to these accessories, your doctor could have prescribed the use of a humidifier. In this
case, check that you have all the accessories for this humidifier specified in its operating instructions.
In the case of an additional oxygen supply, you must also have an adaptor (only in the case where the
oxygen supply is not fitted directly onto the mask). See the chapter “Fitting an oxygen adaptor”. (See
page 8).
Carefully check the device and each accessory. Check especially that the hoses are not damaged and
that the mask does not have any cracks or distortion in the mask housing or seal (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 to the mains using its power supply module, referring to steps 4 and 5 of the
chapter “Standard installation”. (See page 7).
The type of the device is displayed for a few seconds then the following standby screen showing the
hour (the value displayed is given as example):
9:31
(the two points are blinking).
Figure 1 – View of the display when the device is in standby mode
If the device was disconnected while the motor was running, the screen displays the pressure. The
device shows the same adjustments as at the time of the power supply cord disconnection and is set
on the pressure used at the time of disconnection.
Start the device by pressing the ON/OFF button. (See reference 4 in Figure 2, page 5). The blower
should start up and the noise should be regular.
Stop the device by pressing the ON/OFF button and unplug the power supply lead from the mains.
Standby Indicator
WARNING
In the event of problems or if you discover any anomaly, do not start the treatment and contact
your home service provider.
