Operating concept
Operating concept
1 Three rotary control knobs are located in the middle of
the front panel for setting the upper alarm limit for
airway pressure (»Paw«), 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
parameters are adapted to the relevant patient group:
infants (green) / children (blue) / adults (brown).
2 The main switch 0/1 for switching the ventilator on
and off is in the bottom right-hand corner of the front
panel.
3 With the »Air Mix/No Air Mix« switch, the user can
choose between approx. »60 Vol.% 02« and
»100Vol.% 02 «.
4 The pressure gauge shows the inspiratory airway
pressure.
The flag indicators for the alarms are located above the
rotary control knobs for »Freq.«, »MV« and »Paw«:
5 »Pv« Flag indicator
Green if the supply pressure is sufficient.
Red if the supply pressure is insufficient.
6 Indicator for the upper alarm limit »Paw J T «.
Red if the airway pressure exceeds the maximum limit.
7 Red indicator for lower alarm limit »Paw J~ « .
Red if the airway pressure falls below the minimum
limit.
8 Button » fa « for muting the audible alarm tone.
9 Indicator » fo « turns yellow when the alarm tone is
muted.

Operation
IPPV controlled ventilation
Use a prepared, operable and disinfected device.
Care, page 11.
Preparation, page 14.
Checking device ready for operation, page 18.
IPPV controlled ventilation
For ventilation frequencies of 5 to 40 breaths per minute.
For rapid presetting, uniform colour-coded scale ranges
can be used for the rotary control knobs for the
ventilation rate Freq. and minute volume MV. With these
ranges, the ventilation parameters are adapted to the
patient group:
Infants / Children / Adults
1 Presetting the »Freq.« and »MV« control knobs:
Body weight

(7.5 to 20)
28 to 40 3 to 5
Blue range
for children
(20 to 40)
20 to 28 5 to 9
Brown range
for adults
(as from 40)
5 to 20 9 to 20
2 Set the desired 02 concentration with the switch:
Air Mix approx. 60 % 02 by volume
or
No Air Mix = 100 % 02 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 (see also page 29 in the
appendix).
Use the O 2 monitor to detect any error in the
O 2 mixture.
7

Operation
IPPV controlled ventilation
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 »Paw« to the desired Pmax.
The »Paw« setting limits the airway pressure. If the set
»Paw« value is exceeded, the airway pressure is reduced
below the Pmax value. Inspiration is continued. See the
graph Paw (t).
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.
By limiting the pressure during the inspiration time, a
pressure limited, inconstant volume, controlled ventilation
pattern is obtained.
For heart-lung resuscitation
For resuscitation of adults using the "two helper method":
3 Set the »Freq.« knob to the heart symbol ¥ ,
approx. 12 breaths per minute.
4 Set the »Paw« knob to the heart symbol ¥ ,
approx. 55 mbar.
Pressure limiting is activated. On reaching the peak
pressure, under certain conditions, the tidal volume
is not fully applied.
8

Operation
Ventilation with PEEP
Use in toxic environment
Ventilation with PEEP
(Special accessory)
Gebrauchsanweisung des PEEP-Ventils beachten.
1 Set the PEEP valve to 0 mbar = turn the knob
counter-clockwise as far as it will go and fit it to the
waste gas connector of the ventilation valve
Set PEEP = turn knob.
The end-expiratory pressure is increased by the set
PEEP value.
The PEEP pressure is not displayed on the
pressure gauge.
Use in toxic environment
Oxylog 1000 can be used for controlled ventilation of
accident victims in a toxic environment.
For use in toxic environment:
2 Set the switch to »No Air Mix«: the device will supply
100% 02 by volume.
If spontaneous breathing is present or restored, e.g.
after resuscitation, partial spontaneous inspiration of
toxic gases is not prevented by Oxylog 1000.
Immediately move the patient to a breathable
environment in order to prevent the patient inhaling
toxic atmospheric air when spontaneous breathing
is restored.

and remove the cover.
2 Remove the diaphragm. Do not dismantle any further.
• Do not allow any foreign matter to enter the
housing of the ventilation valve.
Protect the diaphragm from damage.
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.

Preparation
Connecting the 02 supply
Connecting the 02 supply
Take care when handling oxygen.
O 2 is highly flammable and intensively propagates
any source of fire.
Do not smoke or allow any naked flame in the vicinity
of the O 2 supply.
Protect O 2 cylinders against falling, and do not
expose them to intense heat.
Do not oil or grease O 2 fittings, such as cylinder
valves and pressure-reducing valves, and do not
handle these parts with greasy hands. Fire risk.
Only open/close cylinder valves by hand, turning
evenly. Never use a tool to open/close the valves.
For supply by O 2 cylinder
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 to the 02 cylinder
(for outlet pressure 2.7 to 6.0 bar, nominal pressure
5 bar).
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.
Do not insert metering valves or flow meters in the
O 2 supply of the Oxylog 1000.
Risk of impaired function of the ventilator with
consequent danger to the patient.
Determining the gas content of the O 2 cylinder
Example:
Cylinder pressure measured at the pressure gauge of the
pressure-reducing valve: 200 bar
O 2 cylinder capacity: 2.5 L
Compressed gas content:
2.5 L x 200 bar = approx. 500 L
16

Preparation
Connecting the 02 supply
Estimated operating time of the Oxylog 1000
Example:
Freq. 10 bpm, VT = 1 L, MV = 10 L/min
Operating time = Compressed gas content, L
(MV +1*) L/min
Operating time = 500 L — = approx. 45 min.
11 L/min
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 2 supply
• Screw the compressed gas hose to the Oxylog 1000
and insert the gas connector in the O 2 supply socket.
For use with the Drager Oxator
• Screw the O 2 compressed gas hose to the
Oxylog 1000.
