Using the Everest 2 CPAP with the Heated
Humidifier and Optional Battery
When the Everest® 3 CPAP and Heated Humidifier are
connected to AC line po er, the CPAP and Humidifier ill
function normally as described in the patient manual. When
po ered by the optional battery assembly ho ever, the device
recognizes the loss of AC line po er and ill enter Enhanced
Energy Management mode (EEM). EEM extends the life of the
optional integrated battery.
Enhanced Energy Management humidification ill have the
follo ing characteristics that deviate from general AC po er
usage:
24
•The CPAP ill not offer preheat. If the unit changes
from AC po er to battery po er during preheat, the
function is suspended until out of battery mode. When
returning to AC po er, the unit ill resume at previous
setting.
•The CPAP ill offer only one humidification setting,
noted ith an asterisk (*) above the humidifier symbol.
•When humidifier shuts off, asterisk symbol ill
disappear and CPAP ill continue therapy ithout
humidification.
•Pressing the humidifier button ill toggle bet een
humidification ‘on’ and ‘off.’
•The humidifier ill automatically shut off after 5 hours
of therapy.
Note: After the Everest 3 CPAP device is disconnected from
AC line po er it ill take 20-40 seconds for recognition
of battery use. Follo ing device recognition of battery
mode po er, the device enters Enhanced Energy
Management mode and ill run the humidifier for a
maximum 5-hour period. After this period the
humidifier ill shut-off, but the CPAP ill continue to
run on battery po er for an estimated 3 hours at 20 cm
H20 prior to battery depletion.

25
Turning on the Blower
1. Ensure that the CPAP device has po er, the blo er is off,
and the preheated humidifier is active.
2. Position the patient interface (mask), according to
the instructions accompanying the patient interface
selected by your care provider.
3. Press the on/off button.
Warning Turn on the blo er as quickly as possible
after positioning the patient interface.
Exhaled air could be re-breathed if the CPAP
blo er is off. Re-breathing exhaled air for
longer than several minutes can, in some
circumstances, lead to suffocation.
When the blo er is on, the display sho s the therapeutic
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 ill automatically reduce the
pressure in approximately 1-60 seconds (depending on
therapy pressure and interface type). This is called
Interface Interrupt (refer to Inter ace Interrupt Feature). It
26
occurs hen your patient interface (mask) is removed
from your face and the air leak is excessive. The display
ill indicate that the therapy pressure has been reduced
due to the Interface Interrupt function.
Secure the interface and the pressure ill increase to
the prescribed level hen you resume breathing (the
display ill indicate therapy pressure).
Note: If the device is left off the face for more than one
hour, it ill shut off the blo er and enter Standby
mode. To resume device therapy, you must press the
on/off button to initiate the CPAP blo er.
Note: The CPAP device recalls the humidity setting during
therapy. The next time you begin therapy or turn on
preheat, the CPAP ill use the same humidifier setting.
Interface Interrupt Feature (if enabled)
The Everest® 3 CPAP ill automatically reduce therapy
pressure hen it detects that the interface has been removed or
has an excessive interface leak ( ithin 1-60 seconds, depending
on therapy pressure setting and interface type). This feature is
intended to minimize disruption to the user or bed partner (e.g.
reduce noise hen taking a bathroom break). The Interface
Interrupt feature also detects hen the interface is returned to
position on the face and breathing is restored (shortly after the
interface is repositioned) and ill restore CPAP to previous
therapy pressure.
Note: If the Interface Interrupt occurs during normal therapy
(indicated by the display sho ing four dashes instead of

27
the therapy pressure), please make sure all connections
to the CPAP are secure and that no excessive leaks have
been introduced. If this feature does not seems to be
orking properly, please contact Clinician or DME for
possible adjustment (reference Troubleshooting table
for additional information).
Enabling/Disabling Interface Interrupt
For Everest® 3 CPAP models, the default setting ill have
Interface Interrupt disabled, and this can only be changed by
the clinician. Once the setting is selected, the value is saved
ithin the device and does not change hen po ered off.
Note: If your CPAP is updated by a prescription created by the
PC Compliance soft are, the Interface Interrupt setting
ill automatically reset to disable. If this needs to be
enabled, the clinician must manually set this or
prescription updates cannot be used.
Note: When the Interface Interrupt Feature is disabled, the
device ill not offer ‘true compliance,’ as therapy session
information ill record hen the device is po ered up
independent of hen the device is actively being used.
28
Using the Ramp Function
The ramp gradually increases the pressure setting, allo ing you
to become accustomed to the positive pressure, so that you may
ease into the therapy hile falling asleep.
Note: If your clinician has instructed you to adjust your ramp
starting pressure, refer to Patient In ormation Settings.
1. The CPAP’s blo er is on:
Note: You must start the blo er 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 sho s
the ramp symbol. During ramp, the pressure gradually
increases to the prescribed pressure level.
Note: The actual pressure delivered during ramp is not sho n
on the CPAP display.

29
Once therapy pressure is reached, the ramp icon ill disappear
from the display screen.
Note: Pressing the ramp button during ramped pressure
delivery ill not affect the pressure delivered. If you
ish to stop the gradual pressure increase of the ramp
function you must turn off the device. The next time
the blo er is turned on it ill deliver the prescribed
therapy pressure.
Note: Interface Interrupt is not active during ramp.
Note: In the event of po er loss during ramp, the CPAP ill
resume at the full prescribed pressure as soon as po er
is restored.
