In 1993, the National Commission on Sleep
Disorders Research stated that as many as
18 million Americans may have signs and
symptoms of Obstructive Sleep Apnea
(OSA). OSA is a condition where the upper
airway relaxes during sleep causing the
airway to obstruct. Apnea is a word
meaning “without breath.” People diagnosed
with OSA stop breathing repeatedly during
sleep which can result in extreme
exhaustion and damage to vital organs.
HOW DOES THE REMREST HELP?
The RemRest is a CPAP (Continuous Positive
Airway Pressure) device which provides
constant non-invasive air pressure to your
upper airway causing the airway to stay
open. In doing so, you are able to sleep
with no interruption allowing your body to
rest and regenerate. Small, adjustable,
lightweight and quiet, the RemRest is our
contribution to reaching your dreams.

Instructions For Use
IMPORTANT SAFEGUARDS
Follow all basic safety precautions. Please
read instructions before using. Precautions
are not limited to the safety information
provided. Important information is
highlighted as indicated:
WARNING
Important safety information for hazards
that might cause serious injury.
CAUTION
Important information to prevent damage
to the device.
NOTE
Information requiring special attention.
6 RemRest
Save These Instructions
The RemRest system consists of a CPAP flow
generator, tubing and a nasal interface.
Other accessories may be used and are
available as needed from your care provider.
Comfortable fit is very important. Please
discuss with your care provider to determine
the best nasal interface that will meet
your needs.
WARNING
Do not under any circumstances plug any
vent holes on your mask. These are for
proper exhaling and plugging them might
cause carbon dioxide buildup. This warning
does not pertain to any capped holes on your
mask. These are for diagnostic purposes and
may remain plugged.
WARNING
This CPAP unit should be used only with
masks (and connectors) recommended by
the manufacturer of the CPAP machine, your
physician, or respiratory therapist. A mask
should not be used unless the CPAP is turned
on and operating properly.
Explanation of the Warning: This CPAP unit is
intended to be used with special masks (or
connectors) which have vent holes to allow
continuous flow of air out of the mask. When
the CPAP unit 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 machine
is not operating, enough fresh air will not be
provided through the mask, and exhaled air
may be rebreathed. Rebreathing of exhaled

WARNING
This device is not suitable
for use in the presence of
a flammable anaesthetic
mixture with air or with
nitrous oxide.
WARNING
This is not intended for
use as a life supporting
or life sustaining device.
It is intended for use
on spontaneously
breathing adults.
WARNING
All settings of your
RemRest are to be
adjusted by authorized
personnel. Settings are the
result of physician
supervised diagnosis and
must not be changed
without physician
authorization.
air for longer than several minutes can in
some circumstances lead to suffocation.
This warning applies to most models of
CPAP units.
CAUTION
At low CPAP pressures, the flow through the
exhalation port may be inadequate to clear
all exhaled gas from the tubing. Some
rebreathing may occur. This warning applies
to devices with rebreathing testing which
demonstrates that rebreathing may occur at
low pressures within the operating
pressure range of the device.
CAUTION
The air flow for breathing produced by this
device can be as much as 4°F higher than
the temperature of the room. Caution
should be exercised if the room temperature
is warmer than 90°F. (This caution applies
to devices in which the temperature of the
output of the device is more than 3°F above
ambient under typical test conditions.)
REMREST TUBING SET-UP
Smooth-bore tubing is designed to deliver
air pressure to your nasal interface. Attach
one end of your tubing to the RemRest air
outlet. The other end of the tubing is used
for the nasal interface. See diagram on
page 5. When humidifier or oxygen
equipment is used with the RemRest
system, please follow the user instructions
provided with the humidifier or oxygen
equipment to set up the system. For best
results, it is recommended you use the
RemRest Heated Humidifier with this device.

RemRest Flow Generator Operation
• Place the RemRest device on a flat, sturdy
surface with the back of the unit away
from heating vents, radiators, curtains
and other objects that could restrict air
intake.
• Secure the mask, connect the tubing, and
prepare any accessories you might use
prior to operation of the RemRest device.
It is recommended that the device be left
plugged in when not in use. This is especially
helpful for Tier 2 and 3. Tier 2 does not have
a battery and therefore only “remembers”
plugged in time with regards to time used
and time plugged in. Tier 3 has an internal
battery and therefore will “remember” all of
its times without being plugged in. However,
it will save the battery if the unit remains
plugged in when not being used, i.e. during
the day.
RemRest Tier 1
There are two options to provide power to
the CPAP: AC or DC power.
1. For AC Power, plug one end of the AC
power cord into the AC inlet plug located
on the back of the RemRest device. Plug
the other end into the wall socket. Go to
Step 3.
2. If using the DC power cord with auto
adapter for operation of the RemRest in a
motor vehicle or recreational vehicle,
insert the plug into the DC jack located on
the back of the CPAP and plug the other
end into the vehicle’s 12V DC outlet.
RemRest 9
NOTE
The device will draw a
small amount of power
when plugged in but
not “On”.
3. The two green lights (on/off light and
ramp light) will turn on for two seconds
then will remain off until the motor/blower
is turned on and/or the ramp function is
