Installing the expiration valve

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

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!

system.

Installing the flow sensor

Flow sensor connection with proximal expiration valve

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.

Flow sensor connection with distal expiration valve

Turn the flow sensor measurement line

connectors upward to prevent conden-

sate from entering the

measurement lines.

The flow sensor is connected between the

expiration valve and the endotracheal tube

(ETT). The images show the additional

connection of a bacterial

filter.

● Function

Flow

This sub-menu consists of functions to

check and configure (as needed) the

flow sensor and trigger. In addition, the

following can be selected here: use of an

expiration valve with either distal or

proximal pressure measurement and use

of either an emergency hose system or

high flow nasal cannula for ventilation.

Standby mode

If the selftest is passed, the standby screen

appears. Initially, it always shows the

ventilation mode and settings for the most

recent ventilated patient. To keep these

settings, press the „Continue Ventilation“

field to activate ventilation.

Press the „New Patient“ field to create a new

patient. To switch to Standby mode from

a current ventilation process, press and hold

the „On/Off/Standby“ button for 3 s.

Using fast tracking keys

The easiest way to start a new ventilation

process is by using the fast tracking keys on

the front panel of the ventilator.

These provide a quick and easy way to select

the default ventilation parameters for preterm

infants and newborns, children and adults.

To prevent operator errors, the desired fast

tracking key must initially be pressed for 0.5 s,

after which it starts to flash green.

Pressing the key again for 0.5 s will then start

or switch to the selected ventilation mode.

Fast tracking key assignment can be

customized in the Setup menu.

New patient

This menu lets the user switch between

settings for preterm infants and newborns,

children and adults. This selection corres-

ponds to the function of the fast tracking keys.

After selecting the patient type, the system

suggests pre-configured ventilation with

ventilation parameters adapted to the corres-

ponding patient type. Press the „Confirm“

button to save the settings and return the

ventilator to the Standby screen.

You can now select the „Start Ventilation“ field.

Press the „Mode Settings“ field to change the

ventilation mode.

„Standby“ menu.

Select „Continue Ventilation“ to activate

the ventilation.

Ventilation settings

Setting parameter PRVC

This option lets the user select a target

volume that guarantees a tidal volume with

minimum required pressure during breaths.

Depending on the patient‘s spontaneous

breathing efforts and lung compliance,

the inspiration pressure varies with the

intention to apply the selected tidal volume

with the minimum required pressure.

Increase the upper pressure alarm

limit to e.g. 40 mbar to avoid pressure

limitation.

Ventilation settings

Setting parameter CPAP PSV

PSV is designed to support insufficient spon-

taneous breathing. It combines the benefits

of pressure-controlled ventilation with the

patient‘s spontaneous breathing activity.

The ventilator uses the selected trigger

threshold to detect the patient‘s inhalation

efforts and then triggers a mandatory breath

using the selected pressure support (Psupp).

With PSV enabled, the ventilator stores the

inspiratory peak flow during inhalation.

Expiration is initiated as soon as the flow has

dropped to the previously set percentage for

the inspiratory peak flow. The Expiration

Trigger Sensitivity (ETS %) is used for this

setting. In pure CPAP ventilation, the Pinsp

setting acts as an parameter for Insp.-Hold.

Ventilation settings

Parameter setting CPAP backup ventilation

CPAP can be combined with backup

ventilation. The user can set the maximum

desired apnea duration in the „Apnea“ field.

If there is no spontaneous breathing during

this time, the ventilator begins mandatory

ventilation using the preset parameters.

The parameter settings for backup ventilation

are comparable to PC-SIMV ventilation.

Ventilation settings

Tube compensation

All invasive ventilation modes can be

combined with tube compensation.

This function lets you adjust the ventilation

pressure to the resistance of the tracheal

or endotracheal tube.

Adjustable parameters:

• Compensation (%)

• Tube diameter (mm)

Stop ventilation

To end the ongoing ventilation and

switch to Standby mode, press and

hold the „On/Off/Standby“ button

for 3 s.

Pressing the button for another 3 s

turns the ventilator off.
