Safety instructions for working with the device
Connecting the device
■The device may only be put into opera-
tion by trained specialist medical per-
sonnel with knowledge of mechanical
ventilation.
■The device may only be connected to
the power supply at permanently instal-
led 230 V standard sockets using the

standard plug.
■Connection via extension cables or
sockets switched by means of wall or
dimmer switches is not permissible.
■Modifications to the existing installation
may only be carried out by authorised
specialists.
Danger
Incorrectly performed connections
can lead to life threatening condi-
tions for the ventilated patient.

General safety instructions
■Do not allow oxygen to flow into
enclosed rooms/spaces as this can
lead to an oxygen-enriched atmos-
phere and consequently may present a
fire hazard.
■Keep away from open flames and
sources of ignition.
Safety instructions for medical per-
sonnel and users
■Oxygen must only be handled by
trained or instructed personnel
■Secure oxygen bottles to prevent them
from tipping over or falling down.
■Always open oxygen valves slowly.
■Keep oxygen fittings and system com-
ponents free of oil and grease at all
times.
■On completion of work, close all oxy-
gen fittings and valves.
■Improper use of oxygen is prohibited,
e.g. using it instead of compressed air
or for cooling or cleaning clothing
■Under no circumstances should leak-
ing or faulty oxygen bottles, fittings or
system components be used.

■VitoAid ventilator
■VentStar Oxylog VE300 single-tube system, length:
1.5 metres
Intended use
The VitoAid ventilator is designed to provide continu-
ous respiratory support to adult patients who require
mechanical ventilation.
The VitoAid ventilator may only be used in emergency
situations where the capacities of the existing supplies
of approved ventilators are not sufficient.
The ventilator is intended solely for use in care facili-
ties and hospitals for invasive and non-invasive posi-
tive pressure ventilation.
Intended use requires the following:
■Ventilation with external oxygen supply:
The ventilator is connected via a silicone tube to a
supply of medical oxygen with pressure control.
■Ventilation without external oxygen supply:
The tube connection for the oxygen supply to the
ventilator is closed (delivered condition).
Introductory information

■The patient is supplied via the VentStar Oxylog
VE300 single-tube system, 1.5 metres (standard
delivery) and HME filter. The HME filter must be
positioned close to the patient.
■The supply tubes comply with the specification for
ventilators.
Usage for a purpose other than invasive and non-inva-
sive positive pressure ventilation shall be deemed
inappropriate.
Incorrect usage or operation of the device (e.g. open-
ing of the device) is prohibited and will result in an
exclusion of liability. Incorrect usage also occurs if the
components of the ventilator or the tubes connected to
it are modified from their intended function.
Your device is preset at the factory
The ventilator is preset at the factory for pressure-con-
trolled ventilation (PCV) with the following parameters:
You can change these settings individually at any time:
See page 15 onwards.
Ventilation parameters
■The positive end-expiratory pressure (PEEP) is set
to 10 millibars.
■The inspiratory pressure is set to 25 millibars.
■The respiratory rate is set to 15 breaths per minute.
■The ratio of inspiratory time to expiratory time is set
to 1 : 2.
Alarm limits
■The alarm limit for expiratory pressure equates to the
setting for positive end-expiratory pressure (PEEP).
■The alarm limit for inspiratory pressure is 45 milli-
bars.
■The alarm limit for the lower respiratory volume is set
to 0. This means that monitoring for this value is
deactivated.
■The alarm limit for the upper respiratory volume is
set to 999. This means that monitoring for this value
is deactivated.
Note
The alarm limits are only active if PCV (pressure-con-
trolled ventilation) is set: See page 15.
Power failure
All settings are retained if there is a power failure.

VitoAid supports PCV (pressure-controlled ventilation)
and high-flow CPAP (continuous positive airway pres-
sure).
Pressure-controlled ventilation (PCV)
The patient is ventilated in controlled mode in accord-
ance with the set values for inspiratory pressure, posi-
tive end-expiratory pressure (PEEP), respiratory rate
and the ratio of inspiratory time to expiratory time.
Spontaneous ventilation is neither detected nor assis-
ted here.
To activate pressure-controlled ventilation, set the
inspiratory pressure higher than the positive end-
expiratory pressure (PEEP).
High-flow CPAP (continuous positive airway pressure)
With this method, a continuous supply of air/oxygen is
administered via a suitable mask to generate a positive
end-expiratory pressure (PEEP), which provides respi-
ratory support to a spontaneously breathing patient.
To activate high-flow CPAP, set identical values for
the inspiratory pressure and the positive end-expira-
tory pressure (PEEP).
If ventilation is switched on, only the expiratory pres-
sure ( ) is shown on the display.
The other information is not relevant for this ventilation
method and is therefore not displayed: See page 12.
Note
With this ventilation method, monitoring of the alarm
limits is switched off.
Setting the positive end-expiratory pressure (PEEP)
The settings for the positive end-expiratory pressure
(PEEP) and the inspiratory pressure are interdepend-
ent. The difference between the two pressures must
not exceed 25 millibars.
Example:
You have set the positive end-expiratory pressure
(PEEP) to 15 millibars.
You cannot set the inspiratory pressure higher than
40 millibars.
If the inspiratory pressure was previously set to a
higher value, this setting will be automatically reset to
40 millibars.

4. Use or to set the required pressure in milli-
bars in the "Service" display area.
The setting is made in millibars.
5. To accept the set value, press again.
Note
The ventilator regulates the respiratory pressure to the
set value. If this value cannot be achieved for pres-
sure-controlled ventilation, an alarm is triggered.
Setting the inspiratory pressure
The settings for the positive end-expiratory pressure
(PEEP) and the inspiratory pressure are interdepend-
ent. The difference between the two pressures must
not exceed 25 millibars.
