Warning
•Caution: Federal law (United States) restricts this device to sale
by or on the order of a physician.
•This device is not intended for life support.
•The Everest®2 Integrated CPAP System must be set up and
adjusted by a trained CPAP provider before it can be used for
therapy.
•When operating properly, the CPAP system flushes out
exhaled air through the vent in the patient interface. Exhaled
air could be re-breathed if the CPAP blower is off, not
operating properly, or the vent is blocked. Re-breathing
exhaled air for longer than several minutes can, in some
circumstances, lead to suffocation.
•The air temperature produced by this device can be as much
as 10ºF higher than the temperature of the room. Exercise
caution if the room temperature is warmer than 90ºF (32ºC).
•In ambient temperatures greater than 95ºF (35ºC), the CPAP
unit must be placed at least 5 feet (1.5m) away from the user.
•Do not block or otherwise obstruct the exhalation ports of
the patient interface. Follow the Patient Interface
Instructions for your interface.
•This equipment is not suitable for use in the presence of a
flammable anesthetic mixture with air or with oxygen or
nitrous oxide.
•Emptying and cleaning the humidifier reservoir daily will help
to prevent mold and bacteria growth.
•Use of accessories or a humidifier other than defined in this
manual is potentially unsafe.
•The CPAP system is only to be used with the supplied and
recommended accessories. Use of accessories not
recommended may result in increased emissions or decreased
immunity of the CPAP system.
•The CPAP system should not be used adjacent to or stacked
with other equipment. If adjacent or stacked use is necessary,
the CPAP system should be observed to verify normal
operation.

3
Oxygen Use Warnings
•If oxygen is used with this device, the oxygen flow must be
turned off when the device is not in operation.
•Turn the device on before turning oxygen on. This will prevent
oxygen from accumulating in the device.
•Do not inject oxygen through the air inlet of the device.
•At a fixed flow rate of supplemental oxygen, inhaled oxygen
concentration will vary depending on the pressure settings,
patient breathing patterns, mask selection, and leak rate.
Caution
•Do not sterilize the CPAP system.
•Power the CPAP system only from the AEIOMed®supplied
power supply, optional battery pack, or mobile power supply.
Reference Appendix 1 for Reorder Numbers.
•Reference the Everest®Integrated CPAP Patient Manual only
after receiving appropriate training in the use of the CPAP
system.
•At low CPAP pressures, the flow through the exhalation port
may be inadequate to clear all exhaled gas from the airway. Some
re-breathing may occur.
•Use patient interface devices with a leak flow rate of at least 12
L/min at 4 cm H2O.
•Contact your healthcare provider if you experience redness or
skin irritation.
•Discontinue use of the CPAP device or humidifier if respiratory
irritation occurs.
•Do not introduce liquids or objects into the CPAP device’s air
inlet/outlet connector.
•Inspect the power cord for signs of wear or damage before each

When a power source is connected to the Everest 2 CPAP
device, the CPAP displays the total number of therapy hours♠
and a flashing hourglass symbol for 3 seconds. Your clinician or
homecare provider may request that you report these hours.
Following the initial display of the therapy hours, the CPAP
device is in Standby mode—the CPAP is ready, the blower is
off, and the display shows the following:
Note: If the CPAP loses power while delivering therapy, it will
immediately resume delivering therapy as soon as power
is restored (the CPAP will skip the initial therapy hours
and Standby screens)
♠Therapy hours = operating time at therapy pressure, as monitored by the device. 16
StartingTherapy
Without humidifier:
1. Make sure that the CPAP device is connected to a power
source. (If necessary, refer to Powering the Everest®CPAP
Device.)
2. Ensure the display is in Standby mode.
3. Attach the patient interface 22 mm airway
connector to the 6’ flexible tubing.
4. Position the patient interface (mask),
according to the instructions
accompanying the patient interface
selected by your care provider.
5. Press the on/off button.
Warning! Turn on the CPAP blower as quickly as possible
after positioning the patient interface. Exhaled
air could be re-breathed if the CPAP blower is
off. Re-breathing exhaled air for longer than
several minutes can, in some circumstances,
lead to suffocation.
6. The blower is on, and the display shows the therapeutic
pressure setting.
7. Check that the hose and patient interface have a tight seal and
that there is no excessive air leak.
Example of the
HeadRest® with
Nasal Seal

17
Note: If you remove or do not securely position the patient
interface, the device will automatically reduce the
pressure in approximately 60 seconds. This is called
Interface Interrupt. It occurs when your patient interface
(mask) is not securely positioned on your face and the
air leak is excessive. Secure the interface and the
pressure will increase to the prescribed level when you
resume breathing.
Note: If you do not breathe with a correctly positioned patient
interface within one hour, the device will shut off the
blower and enter Standby mode.
18
With humidifier:
Warning! The humidifier reservoir must be filled to the
MAX fill line (see humidifier lid) with distilled
water at the start of each therapy session.
Caution! Do not submerge the humidifier in any type
of liquid; damage may occur.
The optional heated humidifier relieves nasal dryness and
irritation in patients by adding moisture to the airflow.
Warning! If moisture collects in the hose (sometimes
referred to as rainout), stop therapy and adjust
the humidity setting. Reducing the humidity
setting usually stops the collection of
moisture.
Warning! Do not spill water into the CPAP air outlet
connector.
1. Remove the humidifier reservoir from the humidifier base.
2. Attach the humidifier base to the bottom of the CPAP
device.

3. Press the on/off button.
Warning! Turn on the blower as quickly as possible after
positioning the patient interface. Exhaled air
could be re-breathed if the CPAP blower is
off. Re-breathing exhaled air for longer than
several minutes can, in some circumstances,
lead to suffocation.
The blower is on, and the display shows the prescribed pressure
setting. Check that the hose and patient interface have a tight
seal and that there is no excessive air leak.
Note: If you remove or do not securely position the patient
interface, the CPAP will automatically reduce the
pressure in approximately 60 seconds. This is called
Interface Interrupt. It occurs when your patient
interface (mask) is not securely positioned on your face
and the air leak is excessive. Secure the interface and

23
the pressure will increase to the prescribed level when
you resume breathing.
If you do not breathe with a correctly positioned
patient interface within one hour, the device will shut
off the blower and enter Standby mode.
Note: The CPAP device recalls the humidity setting during
therapy. The next time you begin therapy, the CPAP
will use this same humidifier setting.
Using the Ramp Function
The ramp gradually increases the pressure setting allowing you
to become accustomed to the positive pressure, so that you may
ease into the therapy while falling asleep.
NOTE If your clinician has instructed you to adjust your ramp
staring pressure, refer to Adjusting Patient Settings.
1. The CPAP’s blower is on:
Note: You must start the blower before selecting the ramp
function. You should adjust your patient interface at the
full therapy pressure setting.
2. Press the ramp button.
The pressure drops to a reduced level and the display shows
the ramp symbol. During ramp, the pressure gradually

Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,1 should
be less than the compliance level in
each frequency range.2
Interference may occur in the
vicinity of equipment marked with
the following symbol:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
1 Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the measured field strength in
the location in which the CPAP System is used exceeds the applicable RF compliance level above,
the CPAP System should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the CPAP System.
2 Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
