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!

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

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.

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=

To facilitate setting, the ventilation ratio

12

a heart symbol.

e

Use in toxic atmosphere

The Oxylog can also be used for
controlled ventilation of injured per­sons 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 measure­ment (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.

Preparation

Assembly of non-rebreathing valve:

Make sure that the red check valve is

fitted in the diaphragm and makes
even contact with the diaphragm.

Fit the diaphragm into the valve hous­ing so that the disc of the check valve
points towards the housing.
The bulge of the diaphragm makes
even contact with the edge of the
housing.

Fit the cover by applying slight
pressure and turn clockwise by about

45”.

Make sure that the diaphragm sits

smoothly in the housing.

Pull the perforated cap at the outlet

over the edge and take it off to check
