How to use these Instructions for Use
The header line ...
specifies the subject of the main chapter.
It is followed by the title of the sub-chapter – to help you find
your way rapidly around the anual.
The page body ...
contains the instructions for use
in a co bination of text and illustrations. The infor ation is
expressed directly in ter s of actions which enable users to
fa iliarise the selves with the operation of the achine by
hands-on activity.
The left-hand column ...
contains the text
which provides explanations and guides the user with brief
and clear instructions in an ergono ic sequence for confusion
free use of the achine.
Bullet points indicate the working steps, nu bers are used to
highlight the relation between the working step described, the
associated illustration(s) and the sequence of operations.
The right-hand column ...
contains the illustration(s
which directly relate to the text opposite and show the user
where to find the ite s concerned. The focus is on the
ele ents entioned in the text. Non-essentials are o itted.
Screen du ps are also used to guide the user and confir the

Charging the battery
●The a bient te perature ust be between 0 and 35 oC
when charging the batteries!
When the external supply is available:
1the green la p » N «, lights up regardless of whether the
ventilator is switched on or off. The battery is being
charged.
2The three-coloured indicator » J « lights up to show the
o entary charge status of the battery:
yellow: while the battery is still being charged,
green: when the battery has been fully charged,
red: if a serviceable battery has not been inserted or
cannot be charged, for instance because the
ventilator is being used outside the te perature
range fro 0 to 35 oC.
Indicators » N « and » J « re ain off while the ventilator is
being operated fro the internal battery.
An Oxylog 3000 charging station connected to the ains
supply can be used to charge the battery externally, see "Order
List", page 102.
●Refer to the anufacturer's technical specifications for
further infor ation on the charging and discharging
characteristics (e.g. e ory effect) of the battery used.
Indication of battery capacity / battery operation
3The current capacity of the battery is indicated by
Oxylog 3000 in 25% incre ents in the botto right-hand
line of the infor ation window when switched on:
— when charging fro an external power supply,
— as the battery is discharged during operation.
Exa ple: 75 % charge
The accuracy of the capacity indication can vary, depending on
the age and degree of use of the battery, see "Technical Data",
page 90.
The capacity indication is overwritten if other, ore i portant
essages have to be displayed on the ventilator.
Additional alar s draw attention to the re aining operating
ti e of the battery.
When operated via the rechargeable battery, the brightness of
the ventilator screen is reduced in order to save power.
The screen brightness is auto atically increased to axi u
for one inute while settings are being ade.

Precautions
Ventilation must be monitored
This equipment must only be used under the supervision
of qualified medical staff, so that if any faults or mal-
functions occur, help is available immediately!
This equipment must not be used with flammable gases
or anaesthetic agents. Danger of fire!
Mobile phones must not be used within a radius of
10 metres of the apparatus.
Mobile phones can interfere with the operation of electrical
edical apparatus and endanger the patient!*
* Dräger edical equip ent fulfils the interference resistance
require ents according to the product-specific standards or
EN 60601-1-2 (IEC 601-1-2). However, depending on the design of
the obile phone and circu stances of use, field strengths ay
occur in the i ediate environ ent of a obile phone that exceed
the li its of the above standards and therefore cause interference.
Do not use the equipment in conjunction with magnetic
resonance imaging (MRI, NMR, NMI !
The apparatus ay alfunction, causing danger to the
patient.
Do not use the equipment in hyperbaric chambers!
The apparatus ay alfunction, causing danger to the
patient.
Avoid pollutants in the ambient air!
Oxylog 3000 uses a bient air for ventilation when the
O2 concentration is less than 100 vol.%.
Pollutants would enter the patient’s body.
Manual ventilation equipment must be kept ready to hand
If the life-supporting function of the ventilator can no longer
be guaranteed on account of a fault, such as a power
failure or break in the edical gas supply, ventilation of the
patient ust be continued without delay using other
ventilation equip ent, such as a anual ventilation bag
Resutator 2000, with PEEP and/or increased inspiratory
O2 concentration if necessary. See Order List on page 102.
Not for use in areas of explosion hazard
This apparatus is neither approved nor certified for use in
areas where co bustible or explosive gas ixtures are likely
to occur.

The operating concept takes into account the various
purposes for which the ventilator is used.
For primary care
When configured accordingly, Oxylog 3000 starts in
IPPV ventilation ode with user-configured starting values
for I:E (1:1.5 as default setting) and PEEP (5 bar as default
setting).
The ost i portant ventilation para eters are set with the aid
of the controls below the screen:
4– Tidal volu e VT [ L],
– Ventilation frequency Freq. [1/ in],
– Max. inspiratory pressure Pmax [ bar],
– O2 concentration O2 [%]
During secondary transfers
different ventilation odes and their para eters can be set in
the screen window via the central rotary knob when selected
accordingly (e.g. Tinsp, PEEP, ∆ ASB, Pinsp)
5To select para eter = turn rotary knob

Preparation
Reusable or disposable ventilation hose sets can be used.
See Order List on page 102.
The Carrier Syste 3000 (optional) – see page 72 – is
available for transport under operating conditions.
The onboard equip ent holder 3000 (optional) – see page 74
– is available for positioning the Oxylog 3000 in the vehicle.
Assemble reusable hose set
●Parts ust always be sterilised before use!
Breathing valve, assembly
2Place diaphrag in breathing valve – ensure that it is
inserted correctly.
3Fit cover and turn approx. 90° clockwise = lock.
4Push flow sensor into breathing valve; note preferred
position as indicated by groove.
5Push angled connector onto flow valve.
1 The rubber disc in the housing must not be removed,
damaged or bent, otherwise the valve will not work
properly and endanger the patient.
●Always use an angled connector. If the angled
connector is not used, incorrect values may be
measured for the minute volume.

Preparation
When using a bacterial filter or HME (Heat Moisture
Exchanger
●Connect the bacterial filter or HME to the angled
connector.
The flow easure ent function on the patient side does not
depend on the use of an HME.
1Connect ventilation hose to socket of breathing valve.
2Connect flow easuring hoses to sockets on flow sensor –
note different dia eters.
3Plug flow easuring hoses into Oxylog 3000.
4Connect ventilation hose to socket on Oxylog 3000.
Bacterial filters increase the breathing resistance and
dead-space volume of the ventilation equipment.
●Do not use electrically conductive hoses! These can
endanger both the ventilator and the assistant during
defibrillation.
●Do not allow pressure to build up at the connector for
flow measurement, otherwise the internal sensor may
be destroyed!

Connect disposable hose set
— instead of the reusable hose set.
The service te perature range of the device is li ited to
–10 oC to 50 oC when using the disposable hose set.
1Connect blue flow easuring hose to the blue socket,
2and the transparent flow easuring hose to the other
socket.
3Connect ventilation hose to socket on Oxylog 3000.
When using a bacterial filter or HME (Heat Moisture
Exchanger
●Connect bacterial filter or HME.
The flow easure ent function on the patient side does not
depend on the use of an HME.
When changing the ventilation hose set
If the reusable ventilation hose set is to be used instead of the
disposable hose set or vice versa:
●Have sockets on device changed by specialists
and
●reconfigure device accordingly, see “Custo er Service
Mode”, page 76.
Do not use disposable hose sets other than those in
the order list. The minute volume may be measured
incorrectly and the device malfunction if other disposable
hose sets are used for ventilation.
●Ensure the flow measuring hoses are correctly
orientated otherwise the volume will be measured
incorrectly.
Bacterial filters increase the breathing resistance and
dead-space volume of the ventilation equipment.
