1 Three rotary control knobs are located in the middle of the
front panel for setting the upper alarm limit for airway
pressure (»Pmax«), the ventilation rate (»Freq.«) and the
minute volume (»MV«).
Uniform colour codes are used to identify different scale
ranges of the »Freq.« and »MV« knobs to help rapid
presetting: with these colour-coded scales, the initial
parameters are adapted to the relevant patient group:
infants (green) / children (blue) / adults (brown).
2 The main switch 0/I for switching the ventilator on and off is
in the bottom right-hand corner of the front panel.

The tidal volume will be equal to the minute volume setting
divided by the rate setting:

The I/E-ratio is fixed to approximately 1:1.5 and changes
slightly depending on the setting. The I/E-ratio is within the
range considered reasonable for most patients during
emergency care and transport.
)
2 Set the desired O2 concentration with the switch:
Air Mix approx. 60 % O
2 by volume
or
No Air Mix = 100 % O
WARNING!
2 by volume
In Air Mix mode, the applied tidal volume VT is reduced at
high airway pressures due to the physical characteristics of
the injector used for the mixing and the O
2 concentration
increases due to the smaller amount of air intake. (See also
page 28 in the appendix).
WARNING!
In toxic surroundings:
— The patient must be ventilated in No Air mix mode in order
to ensure that toxic constituents are not entrained into the
breathing gas.
— The patient must immediately be transferred to a
breathable atmosphere in order to prevent inhalation of
toxic air when spontaneous breathing resumes.
Set »Pmax«
When the patient is connected:
1 Check the »MV« setting and adjust according to the patient.
2 Check the airway pressure on the pressure gauge.
3 Set desired upper alarm limit »Pmax«.
When the desired upper alarm limit set »Pmax« is reached, the
machine limits the airway pressure increase by blowing off part
of the inspiratory flow. Inspiration is continued by the machine.
WARNING!
Watch the pressure gauge and take note of alarm conditions
in order to recognise incorrect ventilation at an early stage
and prevent danger to the patient.

Care
Care
● After each operational use of the ventilator, dismantle and
disinfect the reusable ventilation valve and ventilation hose,
the volume metering parts and the reusable PEEP valve.
● The ventilator and compressed gas hoses must also be
cleaned/disinfected if severely soiled.
● Use the single-use system, consisting of the ventilation
valve, the ventilation hose and the single-use PEEP valve,
only once. These parts are marked:
For single use only!
● Dispose of the single-use components in accordance with
local regulations.
Dismantling
● Remove Oxylog 1000 from its holder.
1 Unscrew the O2 compressed gas hose from the
Oxylog 1000.
2 Remove the ventilation hose from the connector on the side
of the ventilator.
CAUTION!
To remove the ventilation hose, always grip it by the sleeve
and not the spiral stiffening ridges.
Otherwise the spiral ridges may be torn, e.g. at the sleeve, or
the hose may be ripped out of the sleeve.

Care
Dismantling the ventilation valve
Turn the cover about 45o anti-clockwise = unlock, and remove
the cover.
3 Remove the diaphragm. Do not dismantle any further.
WARNING!
Protect the diaphragm from damage.
WARNING!
Do not allow any foreign matter to enter the housing of the

Disinfecting/Cleaning
Use only preparations classified as »surface disinfectants« for
disinfecting. For material compatibility, we recommend
preparations based on
—aldehydes,
— alcohols,
— quaternary ammonium compounds.
Due to possible damage to materials, the following
preparations are unsuitable:
— compounds containing alkylamine
— compounds containing phenol
— halogen-releasing compounds
— strong organic acids
— oxygen-releasing compounds.
For users in the Federal Republic of Germany, we recommend
the use of disinfectants listed in the current DGHM list
(DGHM = German Society for Hygiene and Microbiology).
The DGHM list (published by mhp Verlag GmbH, Wiesbaden)
also specifies the active basis of each disinfectant. For
countries where the DGHM list is unavailable, we recommend
products based on the above active bases.

Care
Wipe disinfecting
Ventilator, O2 compressed gas hose:
● Wipe disinfect with e.g. Buraton 10 F or Terralin. Strictly
follow the Instructions for Use of the disinfectant
manufacturer. Coarse impurities must first be removed with
a disposable cloth.
CAUTION!
Do not allow any liquids to penetrate inside the ventilator or
O
2 compressed gas hose.
Liquid inside the system can impair ventilation.
Immersion disinfecting
Dismantled components of the ventilation valve, ventilation
hose, volume metering parts, not the Volumeter 3000:
● Disinfect in disinfectant bath with e.g. Gigasept FF =
formaldehyde-free.
Strictly follow the Instructions for Use of the disinfectant
manufacturer.
Thoroughly stir the parts in the solution.
Do not clean with hard brushes.
Do not allow any foreign object to enter the inside of the
ventilation valve.
● Rinse thoroughly with Aquadest.
CAUTION!
Allow the parts to dry fully.
If any water remains in the ventilation valve, the ventilation
function may be impaired.
Sterilising
Sterilise as follows if necessary:
Disassembled parts of the breathing valve, ventilation hose
and mask:
● Sterilise in hot steam at 134
accordance with EN 285: at least 3 minutes.
NOTE:
Do not expose the plastic parts to the hot steam for more than
10 minutes, since this can accelerate the ageing of the
materials.

Use only compressed gas cylinders that conform to national
safety standards and have been duly approved.
Use full cylinders with 200 bar cylinder pressure.
● Screw a pressure-reducing valve onto the O2 cylinder (for
supply pressure 2.7 to 6.0 bar).
WARNING!
Use only pressure-reducing valves with an outlet exhaust
valve that limits the outlet pressure to approx. 5 bar in the
event of failure.
● Connect the Oxylog 1000 to the pressure-reducing valve
with the compressed gas hose.
● Open the cylinder valve by turning slowly as far as it will go.

If Oxylog 1000 is switched to »Air Mix«, the gas consumption is
reduced by about 50 %, thereby increasing the operating time
to about 90 minutes.
For supply from a central O
● Screw the compressed gas hose to the Oxylog 1000 and
insert the gas connector in the O
2 supply

In exceptional cases, the Oxylog 1000 may also be supplied
with compressed air, in which case the O
2 concentration is
always 21 % by volume.
For use with the Dräger Oxator
● Screw the O2 compressed gas hose to the Oxylog 1000.
● Insert the gas connector securely into one of the two O2
ports until it clicks into place.

Minute volume and O2 concentration as a
function of airway pressure
Air Mix function
Oxylog 1000 supplies the air/O2 mixture (Air Mix) by means of
an injector that draws in additional air from the atmosphere to
generate an air/O
60 % by volume.
Due to the laws of physics, the suction effect of injectors
decreases with increasing back pressure.
With high airway pressures, the minute volume MV set may be
reduced during the Air Mix function, thereby increasing the O
concentration.
At airway pressures up to 20 mbar, the set and applied minute
volume (MV) are the same. An additional increase of airway
pressure by 10 mbar leads to a reduction of the volume
applied by about 10 %. The set minute volume MV should
possibly be increased appropriately.
Since less air is drawn from the atmosphere when there is an
increase in airway pressure, the O
At a low minute volume MV of under 7 L/min, concentrations
of up to 100 % by volume can be attained.
2 mix with an O2 concentration of about
2 concentration increases.

No Air Mix function
The applied minute volume MV is not a function of the airway
pressure. The O
Minute volume as a function of ambient air pressure
The applied minute volume MV is also dependent on the
atmospheric pressure of the surrounding area (reference value
1013 hPa). If the atmospheric pressure is reduced by
100 hPa, the supplied minute volume MV is increased by
about 10 %.
2 concentration is always 100 %.
