Use with DrSger OxatoP
The connection piece 2M 19051 is
exclusively designed for use of the
Oxylog on the Oxator head (Fig. 8). This
connection piece is screwed to the
Oxator head and consists of a self-
closing, standard O2 coupling for
connection of the Oxylog using the
standard, gas-specific connector (02/
air). A self-closing inlet screw connec-
tion for O2 makes it possible (in addition
to the use of cylinders) to supply the
Oxylog and the other components
connected to the Oxator head (e. g.
humidifier/nebulizer or aspiration ejec-
tor) from a central gas supply unit (see
Oxator Operating Manual).
The Oxylog may not be fed via the flow
control valves at the Oxator head!
Fig. 8 Oxator head with connection piece
for Oxylog
Use of gas blenders
.
In the case of lengthy ventilation, e. g.
during repatriation flights, low, defined
O2 concentrations may be required.
For this purpose a compressed-gas
blender can be connected upstream of
the Oxylog (see Order List).
Caution!
The inlet pressure at the Oxylog must
however be at least 2 bar at a flow rate of
approx. 60 L/min (see BjFunctional
Check<< on page 11).
The switch is to be set to a>No Air Mix<<.
Equipping (Fig. 9)
0 Assemble non-rebreathing valve as
per Fig. 10. Ensure that entire
diaphragm is correctly positioned
and take particular care to ensure
that red check valve is present and
not out of shape. Screw cover to
valve housing (turn 45” in clockwise
direction).
0 Attach ventilation tubing to socket at
Oxylog as well as to ~~lnspiration~~
socket on non-rebreathing valve.
0 If use is made of an (optional)
externally adjustable pressure limit-
ing valve (see Order List), attach this
valve first to the socket at the Oxylog
and then connect the ventilation
tubing to the socket of the pressure
limiting valve.
0 If PEEP is being applied, insert PEEP
valve (see Order List) into waste-gas
socket of non-rebreathing valve.
0 Set airway pressure gauge to zero.

= approx. 54 min
(10 + 1) L/min
Switching to )jAir Mixes reduces the gas
consumption by 50%, i. e. the usage
period is increased to roughly 100 min.
Testing safety valve
With the same device settings and with
the patient connection sealed at the
non-rebreathing valve the max. airway
pressure should be between 50 and 80
mbar.
Testing compressed-gas supply and
minute volume
Insert catheter adapter, size 5 (M 25569)
into patient connection of non-rebreath-
ing valve.
Read off the max. inspiration pressure
at the airway pressure gauge for the MV
settings: 7, 15,20.
MV 7 L/min
Airway pressure 4 to 8 mbar
MV 15 L/min
Airway pressure 15 to 24 mbar
MV 20 L/min
Airway pressure 28 to 38 mbar
The Oxylog should switch at regular
intervals from inspiration to expiration.
The operating prerequisites (at least 2

Operational Use
The airway pressure gauge must be
observed all the time so that incorrect
ventilation can be detected in due time,
thus precluding risks for the patient!
Set ventilation ratio and minute volume
(MV) to suit patient concerned.
For rapid presetting:
The ventilation ratio and minute volume
(MV) scales each have three colour
bands for the specific patient groups
infants, children and adults.

_. _ .:
If both rotary knobs are set to a band of
the same colour, the following ventila-
tion values are obtained:
Green band
for infants
(5-20 kg
body weight)
Blue band

The switch is to be set to a>No Air Mix<< or
to a,Air Mix<< depending on the patient’s
requirements:
High O2 concentration required:
b>No Air Mixa (and O2 drive)
In the case of a toxic atmosphere (and
respiratory standstill): DNO Air Mix<<
a>No Air Mix<< setting:
The drive gas, e. g. Op, is routed
unblended to the patient. The
ventilation ratio and MV settings
remain unchanged irrespective of
the switch setting.
Low O2 concentrations required:
BBAir Mix<< (with 02 drive)
or compressed-air drive
Small gas supply: a>Air Mix<<
a>Air Mix= setting:
The drive gas (0, or air) is blended
with ambient air. With O2 drive and
an MV setting in excess of 7 Llmin
the percent by volume added is
approximately 50%, i. e. the O2
concentration is roughly 50 vol. %.
With an MV setting less than 7
Urnin the O2 concentration in-
creases up to 80 vol. %.
Connect non-rebreathing valve to mask
or tube.
Make sure that airways are completely
free.
Check airway pressure gauge.
In normal circumstances the inspiratory
airway pressure values should be
approximately 20 mbar.
Atypical airway pressures
In the event of an excessively high
airway pressure reading, the MV
setting should first be checked as well
als the functioning of the non-rebreath-
ing valve.
Ensure that airways are completely
free!
High airway pressure (50-70 mbar) in
conjunction with a buzzing noise (safety
valve in device blowing out) are an
indication of incorrectly positioned
airways or a kinked tube.
If the airway pressure reading is too
low, the MV setting must likewise be
checked.
The hose connections are also to be
tested for tightness and freedom from
leaks and the non-rebreathing valve is
to be checked for proper functioning.
Ventilation ratio for cardiopulmonary
resuscitation
Within the scope of cardiopulmonary
resuscitation of adults employing a ratio
of 1:5, it must be ensured that a
ventilatory impulse is given after every
5th cardiac compression.
Given a cardiac massage frequency of
60 min-’ this means that ventilation
must be effected with a ratio of
min-‘.
y= 12
To facilitate setting, the ventilation ratio
12 min-’ on the Oxylog is provided with
a heart symbol.

e
Use in toxic atmosphere
The Oxylog can also be used for
controlled ventilation of injured per-
sons in a toxic ambient atmosphere. The
switch setting >>No Air Mix<< is to be
employed for this purpose.
If the patient breathes spontaneously or
if spontaneous breathing has been
restored after resuscitation the partially
spontaneous intake of toxic ambient air
is not prevented by the Oxylog.
It is for this reason that the special
Oxylog with spontaneous breathing
device (cf. Order List) must be used.
This device facilitates spontaneous
breathing with an airway pressure 0 to
be carried out in addition to controlled
ventilation (pay attention to respective
Operating Manual).
Note
In the case of spontaneous breathing
the mask must always fit snugly, so as to
prevent the intake of toxic ambient air.
Ventilation with PEEP
(Special accessory)
Pay attention to respective Operating
Manual.
Set PEEP valve to 0 and push it onto the
waste-gas socket of the non-rebreath-
ing valve:
Determine inspiratory airway pressure
at airway pressure gauge.
Set PEEP value:
The endinspiratory pressure increases
approximately by the set PEEP value.
Should the airway pressure rise higher
or not change its value at all, the PEEP
valve is defective and must be replaced.
Upon termination of the PEEP mode the
PEEP valve must be removed from the
valve of the airway pressure gauge.
Use of pressure limiting valve
(special accessory)
Set rotary knob at optional pressure
limiting valve (located on inspiration
socket at Oxylog) and check inspiration
pressure limited in this manner on
airway pressure gauge.
Caution!
In the case of pressure-limited ventila-
tion the set MV does not have the full
effect. It is advisable to set the pressure
limitation roughly 10 mbar in excess of
the inspiration pressure, so that the
pressure limitation only becomes effec-
tive in exceptional circumstances (e. g.
coughing).
Use of expiratory volume measure-
ment (special accessory)
Insert hose nozzle into waste-gas
socket of non-rebreathing valve.
Connect Volumeter 3000 to silicone
tubing (1.1 m).
The Volumeter 3000 can be used to
measure both the tidal volume and the
MV (pay attention to the respective
Operating Manual).
Caution!
Expiratory volume measurement is not
possible when using the PEEP valve.
Shut-Down Actions
Set main switch to ~~0~~. When using
compressed-gas cylinder, close cylin-
der valve.
