On/O/Standby-Button
Press this button to switch the EVE
on/o or, in the case of ongoing
ventilation, to switch it to Standby
mode.
Fast tracking keys
To prevent operator errors, the desired fast
tracking key must be pressed for 0.5 s,
aer which it starts to flash green.
Pressing the key again for 0.5 s will then
start or switch to the selected ventilation
mode.
Acoustic alarm suppression
If the key is pressed again within 5 s,
the alarm suppression is canceled.
Pressing the key again aer 5 s has
passed will start an new 2 minute
countdown.

2 Button „Inspiration Hold“
3 Button „Aerosol“
4 Toggle button „Day/Night“
5 Control knob „IGR“
6 Lock/Unlock touchscreen

Functional description
Button „Preoxy“
Press the „Preoxy“ button to administer
a pre-adjustable inspiratory oxygen
concentration for a certain preset
interval. These settings can be con-
figured in the „System Settings/Function“
menu. At the same time, the display of
the set oxygen concentration changes
to the pre-set „preoxy“ value. The alarm
limits for oxygen concentration are
adjusted automatically. The button
is green while pre-oxygenation is in
progress.
Button „Inspiration Hold“
Pressing this button during inspiration
will hold inspiration at the end
of the normal inspiration phase for
the duration for which the button is
pressed (maximum 15 s). Pressing
the button during expiration will
trigger a mandatory inspiration using
the set ventilation parameters.
Button „Day/Night“ Toggle
This button lets you toggle the
display, alarm indicator and
patient/function buttons
between day and night mode.

Functional description
Button „Aerosol“
Press the „Aerosol“ button to switch on
aerosol nebulization. The medication
nebulization duration can be set to
between 5 and 30 min in the „System
Settings/Function“ menu. The nebu-
lization ends automatically at the end
of the set time or when the button is
pressed again. The button is green
while nebulization is in progress.
Aerosol nebulization is only possible if
O2is connected to the ventilator.
Lock/Unlock Touchscreen
Pressing the control knob for three
seconds will lock the touchscreen.
Press the control knob again for three
seconds to unlock the touchscreen.
When you tap the locked touchscreen,
a lock icon appears in the „System
Settings“ field.
Control knob „IGR“
Use the control knob to select and
activate all indirect functions.
The control knob has the following
functions:
• Switching within the menus
• Selecting and executing menu
functions
• Selecting and confirming parameter
settings

To connect the oxygen cylinder:
• Fit the oxygen cylinder to the bracket on the
mobile stand and secure.
• Connect the pressure regulator
• Connect the O2hose to the O2input on the left
side of the EVE.
• Slowly open the valve and then slowly
release it completely.
Note safety instructions
Changing the oxygen cylinder
• Hand-tighten the valve on the gas cylinder
• Drain any residual gas from the pressure
regulator via the output until the pressure
gauge on the pressure regulator shows „0“.
• Loosen the O2nist screw connector from
the O2input
• Loosen the fastening buckles on the
support frame and carefully remove the
oxygen cylinder
• Remove the pressure regulator from the
valve by turning the screw connector
counter-clockwise and connect to the
new cylinder
• Place the new cylinder in the support
frame and close the fastening buckles
• Fit the O2nist screw connector to the
O
2input
• Open the pressurized gas cylinder‘s valve
Preparation for use

Connection to the central gas supply
If the device is not operated with an oxygen
source, it must be connected to the CGS.
Connect the O2hose to the O2connector on the
left side of the EVE and to the CGS wall outlet.
Connection to a low pressure
oxygen concentrator
When using oxygen with a concentration of
93% an adapter must be screwed on to EVE‘s
oxygen inlet and the „LPO“ option must be
activated.
Preparation for use
„LPO“ adapter,
Art.-No. 107061187
The input flow must be at least
3 l/min. The Fio2setting on the
device is deactivated.
The oxygen concentration must be
set on the concentrator.

1 Start/Test EVE with double limb tube
system (Art.-No. 107061203) and Y-piece

The EVE lets you use both distal (away from the
patient) and proximal (close to the patient)
expiration valves.
A proximal expiration valve is used only with the
emergency hose system for adults.
The distal expiration valve is used for all other
hose systems.
The distal expiration valve is connected directly
to the expiration port and linked to the tube
system.
Carefully insert the expiration valve in
the corresponding connection on the right
side panel and allow to engage.
Do not tilt the expiration valve or press it in
with force. Danger of breakage!
Installing the expiration valve

Installing the flow sensor
EVE measures pressure and flow via the flow
sensor (PNT). The measurement is taken
proximally between the Y-piece and the tube
connector. For this purpose, a flow sensor
head is fitted between the two parts.
The dierential pressure resulting from the
flow sensor head‘s resistor is a measure of
the volume flow. Separate flow sensors are
available for adults and children.
The flow sensor is connected between the
expiration valve and the endotracheal tube
(ETT). The images show the additional
connection of a bacterial
filter.

Turn the flow sensor measurement line
connectors upward to prevent conden-
sate from entering the
measurement lines.

This display indicates the current ventilation
mode, the active additional functions, the patient
type and the flow sensor type.
Selecting a non-invasive ventilation mode causes
the display to turn orange. In addition, the icon
for non-invasive ventilation appears.
