The DeVilbiss SleepCube™ should be used only with masks recommended
by DeVilbiss, your physician or respiratory therapist.
To avoid rebreathing of exhaled air, do not use a CPAP mask unless the
device is turned on and providing a supply of air. Venting in the mask
should never be blocked. When the device is turned on and providing a
fresh supply of air, exhaled air is flushed out of the mask vent. However,
when the device is not operating, exhaled air may be rebreathed.
Rebreathing of exhaled air for longer than several minutes can in some
circumstances lead to suffocation. This warning applies to most CPAP
devices.
The DeVilbiss SleepCube is not a life support device and may stop
operating with certain device faults or with a power failure. It is intended
to be used on spontaneously breathing individuals weighing 66 lbs/30 Kg
or greater.
To avoid electric shock, always unplug power cord from wall outlet power
source when performing cleaning.
Use only accessories recommended by DeVilbiss.
CAUTION–The circular data port connector located on the back of the SleepCube is used to
attach accessories to the device. The connector must only be used with accessories approved for
use by DeVilbiss. Do not attempt to attach any other device to this connector as it may damage
the CPAP or the accessory device.
CAUTION–Never rinse or place the device in water. Never allow liquids to get into or around
any of the ports, switches or air filter; doing so will result in device damage. If this occurs,
discontinue use and remove the power cord from the power source. Allow the device to
completely dry before use.
CAUTION–Do not place the SleepCube where it can be bumped onto the floor or where the
power cord may create a trip hazard.
CAUTION–Only the DeVilbiss DV5 series Heated Humidifier system is recommended for use
with the SleepCube. Other humidifier systems may prevent the device from detecting snoring and
may cause inappropriate pressure levels in the mask.
CAUTION–Oxygen is a prescription gas and should only be administered under the supervision
of a physician.

Intended Use/Indications for Use
The DeVilbiss® SleepCube™ Model DV5 Series is intended for use in treating obstructive
sleep apnea in patients 66 lbs/30 kg and above.
Contraindication
Do not use SleepCube if your upper airway has been bypassed.
NOTE–Symptoms of dryness of the throat, nasal passages, and the mouth are common with positive airway
pressure therapy. This is especially true in dry climates and during the cold season when humidity in
the air is typically lower than at other times. The SleepCube features an optional humidifier system
to help minimize these effects.
What Is Obstructive Sleep Apnea (OSA)?
Obstructive Sleep Apnea (OSA) is a breathing disorder that affects more than 22 million
Americans – approximately 4% of middle-aged men and 2% of middle-aged women.
Physiological factors such as size of tonsils, shape of the nose, narrowing of the upper airway,
or any combination of these can contribute to the potential for having OSA. During sleep,
your airway can relax so much that it begins to collapse and becomes obstructed. Relaxation
allows the tissue at the back of your throat to vibrate as you breathe causing snoring. But as
your airway collapses more fully, it blocks your airflow and stops your breathing altogether.
(In fact, the word “apnea” is derived from a Greek term meaning “without breath.”)
This stoppage occurs repeatedly throughout the night, each episode lasting from just a few
seconds to more than a minute. As your blood oxygen level drops to dangerous levels, your
central nervous system triggers a sudden gasp for breath, partially awakening you and
preventing you from experiencing the sustained, deep sleep your body needs. As a result, it
is common to feel fatigued, stressed and irritable the following day – a less-than-optimal and
potentially dangerous condition in which to work, drive, and make decisions.
There are important medical concerns as well. OSA starves your heart, brain, and organs of
life-sustaining oxygen. Over time, this deprivation can seriously impact your health

potentially resulting in memory loss, impotence, hypertension, coronary disease, strokes,
and heart attacks. Recent studies indicate that OSA has the same risk factor for heart
disease as smoking, high cholesterol and alcohol, and estimate that as many as 38,000
people a year die from the effects of OSA.
Clearly, OSA is a serious medical condition that requires attention and treatment.
How CPAP Therapy Works
There are several treatments for OSA including surgery and CPAP therapy. However, CPAP
therapy has proven very effective for most patients. CPAP stands for “continuous positive
airway pressure” which is exactly what the DeVilbiss SleepCube device delivers to your
upper airway, acting as an “air splint” to keep the passage open while you sleep.
This reduces or eliminates the obstruction, allowing you to enjoy the deep, refreshing,
uninterrupted sleep you need. More importantly, your body will get the rest and oxygen it
needs with more continuous, uninterrupted sleep – helping you avoid some of the serious
health risks associated with OSA. And the SleepCube is designed to provide this therapy to
you quietly and comfortably so that you can sleep through the night without distraction.
The DeVilbiss SleepCube AutoAdjust® system automatically adjusts air pressure by
measuring your snoring and breathing patterns on a breath-by-breath basis, and
compensating to meet your pressure needs. Your breathing patterns are continuously
analyzed, stored and used to make any needed pressure adjustment.
The rate of pressure adjustment can be as high as 10 cmH2O in a 10 minute period with
changes made gradually enough to prevent disturbing your sleep yet quickly enough to
respond to your pressure needs. In the absence of respiratory events, the pressure is
reduced to maximize your comfort. The SleepCube AutoAdjust is also capable of operating
in CPAP mode – without the automatic functionality described above – to give your
physician maximum versatility in prescribing treatment for your sleep condition.
Acclimating To Your Therapy
Naturally anything new – including CPAP therapy – takes some getting used to. Having your
mouth or nose (or both) covered by a mask may make you feel anxious or claustrophobic.
Feeling the rush of air from your SleepCube may cause discomfort or concern. But don’t
worry – every successful, long-term CPAP user began where you are today with the same
reactions and concerns, and overcame them to enjoy the full benefits of their therapy.
Here are some steps to help you gradually ease into your therapy and overcome your
anxieties:
1. Try attaching the mask to the CPAP unit, and switching the unit “On.” Practice
breathing through the mask for one hour while watching television, reading, or
performing some other sitting activity.
2. If you nap, use the CPAP during this time.
3. Use CPAP at least during the first initial 3-4 hours of nighttime sleep.
4. Use CPAP through an entire night of sleep.

SE-DV54
EN
introDuction
Advance through the above steps one step at a time and progress to the next step as soon
as you can carry out the current step without anxiety.
Benefits Of Your Therapy
As a DeVilbiss SleepCube user, you are on your way to living a happier, healthier life – a life
free from the sleep disruptions and health risks associated with OSA. After you become
acclimated to CPAP therapy, you may be surprised at how much better you feel, both
physically and emotionally. CPAP therapy may give you the opportunity to finally experience
the deep, restful sleep you’ve been missing out on. Many patients find they have more
energy, better judgment, and improved concentration during the day. With effective therapy
you’ll be less stressed, less irritable and more like your old self again, with a healthy, positive
outlook on life. In fact, you may well wish you’d gotten your SleepCube sooner!
Helpful Resources
As you begin your SleepCube therapy, remember: you’re not in this alone! You’re part of a large
and growing network of CPAP users, and many resources are available to answer your questions,
address your concerns, and help make your therapy as effective and effortless as possible.

heater controls and status are displayed as noted in the image.
NOTE–If the display on your device is not similar to those listed above,
refer to the chapter section titled “Patient Messages” on page 15.
Using The Comfort Delay Feature
Your SleepCube has a comfort delay feature to help make it easier for you to fall asleep. The
airflow will start at a low pressure and then gradually ramp-up to the prescribed setting over
the last few minutes of the specified delay time.
NOTE–When the delay comfort feature is activated, a message will flash on the display periodically,
indicating the amount of time remaining in the delay.
You can adjust the amount of time spent in comfort delay by
using the advanced device controls. The Delay Time can be
adjusted from 0 to 45 minutes in 5-minute increments. Refer to
page 12 for details.
NOTE–If you are unable to change the delay time, your provider has locked this setting. Refer to the
keypad menu guide on page 12 for details.
Comfort Delay Feature In Standard CPAP Mode

Press the delay button to activate the comfort delay feature. The airflow pressure will drop to
the prescribed comfort delay pressure.
In the final 10 minutes of the delay period, the pressure will gently rise to the pressure
prescribed for your therapy. You may repeat the comfort delay by pressing the delay button
again if you have not fallen asleep during the first use.
Comfort Delay Feature in AutoAdjust Mode
When you use the comfort delay feature while your SleepCube is operating in AutoAdjust
mode, the airflow you receive at the beginning of your therapy is the lowest pressure
prescribed by your physician when the device was setup.
You do not need to activate the comfort delay; it will turn on automatically. The airflow
pressure will rise only to the low pressure setting and remain there for the duration of the
delay period. The AutoAdjust will not adjust the pressure setting during the comfort delay
period, allowing you to fall asleep without responding to early respiratory events.
Shut Down
Press the ON/OFF button to turn the device off. You may also simply remove your mask.
After a few seconds the device will display the message “Mask Off. Please check mask fit.” If
you do not put the mask on again the device will automatically turn off in about 20 seconds.
Pressing any button will remove the message from the display.
NOTE–If the DeVilbiss SleepCube does not turn off automatically, the feature may have been disabled. In this

press any key or button to clear the message from the display, but the SleepCube will
operate normally even if the message is not cleared.
Two kinds of messages are displayed: Reminders and Notifications.
Reminders
Reminders alert you when parts of your system need to be replaced. Some components of
your system wear over time and, if not replaced, may compromise your therapy. If you see
a message on the display that is not listed below, you may have the optional DeVilbiss
SmartLink™ Module attached to your device, which provides additional messages. Refer to
the documentation that was provided with the SmartLink Module.
Clean Filter – The filter should be checked every 10 days for signs
of dirt or wear so that it can be cleaned as needed. This message
helps to remind you to check it regularly.
Notifications
Notifications identify conditions in your SleepCube that may require action by you or your
home care provider in order to maintain a high level of therapy. If you see a message on the
display that is not listed below, you may have the optional DeVilbiss SmartLink Module
attached to your device, which provides additional messages. Refer to the documentation that
was provided with the SmartLink Module.
NOTE-The values displayed are examples only.
Delay Running xx Minutes Left – While a comfort delay is active,
this message is flashed on the display every 5 seconds to let you
know how much time is left in the delay.
Mask Leak – This message means the SleepCube has detected a
large amount of airflow during therapy for at least 10% of the time
during your previous use session. This notification is displayed when
the device is turned on. If this message is displayed, put on the mask and adjust the headgear
to ensure the mask is properly fitted to your face. Follow the mask manufacturer’s directions
for adjusting the mask and headgear for proper fitting. Available on AutoAdjust models.
Mask Off – This message appears whenever a high airflow
condition occurs. High airflow is normally due to a poor mask fit or
a removed mask. Check for leak around the mask seal and make
adjustments as necessary according to the mask manufacturer’s instructions. This message
will be displayed until the high airflow problem is corrected. If the high airflow condition
persists for about 20 seconds, the device will automatically turn off (if AutoOFF is enabled).
Device Fault – If a device fault message is displayed, refer to
Troubleshooting for instructions.

International Power Changes
Your DeVilbiss SleepCube is equipped with a universal power supply. This means that it is
automatically capable of accepting line voltages of 100 to 240V~ 50/60Hz. You do not need
to make any adjustments to the device if you are traveling to another country where the line
voltage is different than your domestic line voltage. Simply contact your home care provider
for the correct style power cord for the region in which you will be traveling (refer to
Accessories/Replacement Items for the correct part number).
Altitude
Your SleepCube automatically compensates for changes in altitude between sea level and
9000 ft (2750 m). You do not need to make adjustments to the device for changes in
altitude.
sleePCUbe DC oPeRaTion
Battery Power
Your SleepCube can be operated from a 12V DC power source in a motor home, boat or
other recreational vehicle. The power source can be used with a 12V DC accessory cable
or a 12 V DC stand-alone battery. Both parts are available from your home care provider
(refer to Accessories/Replacement Items for the correct part numbers). Both accessory
cables are required for stand-alone battery operation. The stand-alone battery connection
uses clamps that attach to the terminal connections of the battery.
NOTE–The heater for the SleepCube’s humidification system will not operate directly from a 12V DC power
source. If you need humidification, passover humidification is still available. Alternately, instead of
connecting12V DC power directly to the SleepCube, you can pass the DC power through an inverter
that will deliver AC power to the system. This will allow the heater to function. The power rating of
the inverter must be at least 200 watts @ 110V~ / 400 watts @ 220V~.
NOTE–The SleepCube will automatically switch power sources between AC and 12V DC if both sources are
available. If your unit is connected to both AC and 12V DC power sources, it will operate on AC
power as long as AC power is present, and automatically switch to 12V DC power if AC power is
lost. When AC power is restored, it will return to the AC source. You do not need to reset or adjust
any settings when the power source switches, but remember that your heater will not operate on
12V DC.

Supplemental oxygen is sometimes prescribed in addition to CPAP for treatment of
Obstructive Sleep Apnea. If your physician prescribed oxygen for your sleep therapy, you
can add the oxygen in one of two ways:
1. Obtain the optional oxygen adapter (part #7353D-601) from your home care provider
and connect it to the outlet port on the SleepCube. Connect one end of the air supply

tubing to the open end of the adapter and the other end of the air supply tubing to the
mask.
2. If your mask is equipped with an oxygen port, your physician may request that you
apply oxygen directly to your mask.
WARNING-OXYGEN USE
Oxygen supports combustion. To avoid possible physical injury, do not
smoke while using this device with supplemental oxygen. Do not use this
device near hot objects, volatile substances or sources of open flames.
Always turn on the SleepCube before turning on the oxygen source. Turn
the oxygen source off before turning off the SleepCube.
This device is not suitable for use in the presence of a flammable
anesthetic mixture with air or oxygen, or nitrous oxide.
At a fixed flow rate of supplemental oxygen, the inhaled oxygen
concentration will vary depending on the pressure setting, patient
breathing pattern, mask selection, and leak rate. This warning applies to
most types of CPAP devices.
Never allow the oxygen source to run continuously while connected to the
SleepCube if the device is not in use. If the SleepCube is not being used,
turn off the oxygen flow.
CAUTION–Oxygen is a prescription gas and should only be administered under the supervision
of a physician.
CAUTION–The flow setting of the oxygen source must be specified by a physician.
