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
Air
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
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.
Set main switch to
When using
compressed-gas cylinder, close cylin-
der valve.
