Intended Use

The Oxylog is a ventilator for providing
controlled ventilation of infants as of 5

kg body weight and adults on a

time-

cycled, volume-constant basis. The
device is designed for mobile use by
rescue services, for transportation to
hospitals in ambulances or helicopters,

Mounting and Usage

of Holder

The Oxylog is secured in position in the

rescue vehicle by way of the holder

8404560 (Fig. 4).
The screws for attaching the basic

element are provided.

Mounting of holder

The basic element 16 is provided with
sufficient holes for the fastening screws.

At least 3 screws (with maximum

possible spacing between them) are to
be used in each case. The installation
location is arbitrary.

Insertion of Oxylog into holder

Push device into holder such that stems
of two studs 7 on housing slide into slots

16a of holder. Studs must engage in

hole in brackets 17.
Press on brackets 17 to ensure that the

device is firmly secured in position in
the holder.

The guide stud 19 secures the device on
the back. Fig. 5 illustrates the Oxylog in
position in the holder.

Removing Oxylog

Pressing open the two brackets 17
releases the studs 7 and enables the

device to be removed from the holder.
Holder with rail bracket (Fig. 6)

The holder is used for attachment to the

Drager

wall rail system (10 x 25 mm

section).

Handling is the same as for the holder

8404560.

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 connec­tion 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 ejec­tor) 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!

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

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 limit­ing 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.

Preselect O2 concentration
