The Puritan Bennett GoodKnight 420 Evolution device (GK420 Evolution) is
intended for the treatment of patients suffering from Obstructive Sleep Apnea
Syndrome (OSAS). The main characteristic of this pathology is the occurrence o
multiple respiratory events caused by contraction of the upper airways, that disturb
sleep. The GoodKnight 420 Evolution 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 use of this device. Therefore, please read
this manual carefully before using the GoodKnight 420 Evolution.
The information contained here is intended to help you use this device unde
optimum conditions of safety and operation. For any questions relating to the
equipment and its use, contact your medical team or your home care provider.
Your doctor has decided on the treatment of your illness. He/she has prescribed the
different parameters that the hospital or your home care provider will set. The home
care provider will adjust these parameters, as needed.
CAUTION
Federal (U.S.A.) law restricts this device to sale by or on the order of a physician.

Revision A
Indications for use
The GoodKnight 420 Evolution device is indicated for use in the treatment of obstructive respiratory
sleep disorders, particularly Obstructive Sleep Apnea (OSA). Patients who have been diagnosed with
this condition may use the GoodKnight 420 Evolution if they weigh over 66 lbs (30 kg) and are able
to breathe spontaneously. Their treatment may be administered either in a homecare or hospital
environment.
Precautions for use
Clinical research indicates that CPAP therapy may be contraindicated for patients with any of the
following pre-existing conditions:
· Extremely low blood pressure
· Pneumothorax or pneumomediastinum (collapsed lung/air trapped in the lung tissue or in the
tissue between the lungs)
· Severe bullous emphysema or previously complicated by pneumothorax
· Massive epistaxis or previous massive epistaxis (nose bleed)
· Decompensated cardiac insufficiency or hypotension, especially in case of depletion in blood
volume or cardiac rhythm disorder (inadequate blood pressure)
· Pneumoencephalus (air trapped around the spinal cord), traumatism, or recent surgery with the
after-effect of a cranio-nasopharyngeal fistula (abnormal opening between head, nose, and throat)
· Acute sinusitis (inflammation of the sinus cavity), otitis media (earache), or perforation of the
tympanic membrane (eardrum)
· Severe claustrophobia (fear of being shut up in a confined space).
Modem transmissions
When it is time to review the information stored on your GoodKnight 420 Evolution, your home
care provider may set up a modem connection, which is a telephone communication device. The
modem translates computer signals into telephone signals that are sent and converted to computer
data that will be reviewed with SilverLining 3 special software.
NOTE
Your home care provider will set up the modem connection, and instruct you on how to use it.

Revision A
Checking the components
To use the GoodKnight 420 Evolution with its specific electrical power supply, you must be
provided with the following items at least:
· A spiral tubing enclosing a second small transparent tubing
· A nasal-mask (often called an “interface”) and all related accessories as specified in the
instructions for using this interface.
In addition to these accessories, your doctor may have prescribed the use of a humidifier. In this case,
ensure that you have all the accessories required for this humidifier, as specified in its operating
instructions.
In the event that an additional oxygen supply is needed, you must also have an adaptor (but only in
cases where the oxygen supply is not fitted directly onto the interface). Refer to the chapter “Fitting
an oxygen adaptor”. (See page 8)
Carefully examine the GoodKnight 420 Evolution and each accessory. Check the tubings for damage.
The interface should not have any cracks or distortion in the cup and bellows (part of the mask
coming in contact with the face).
Verify that the GoodKnight 420 Evolution and the specific power supply module have no external
damage, verify that there is no obvious fault. Connect the device to the mains using the 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 a guide only) ; the device’s display should show the time in the
24 hour format:
¹
11:23
Standby Indicator
(the two points are blinking).
Figure 1 – View of the display when the device is in standby mode
If the device was disconnected while it was running, the screen displays the pressure. The device
shows the same mode as at the time of the power supply cord disconnection and is set on the pressure
used at the disconnection time.
Start the device by pressing the ON/OFF button (see Figure 2, page 5). The turbine should start up
and the noise should be regular.
To stop the device, press the ON/OFF button and unplug the power supply lead from the mains.
WARNING
In the event of problems or if you discover any anomaly, do not start the treatment and contact
your home care provider.
