Oxygen enrichment of the inspiratory air in case of
spontaneous respiration
• With oxygen reservoir bag or without an oxygen reservoir:
Attach a mask to the resuscitator, set the oxygen flow to between 2 and 4 l/min,
and place the mask over the patient’s mouth and nose, creating an airtight seal.
If the spontaneous respiration is sufficient, an oxygen concentration close to
100
%
will be obtained.
• With an oxygen reservoir tube:
The end of the resuscitator with the oxygen reservoir that normally faces away
from the patient can also be used for oxygen enrichment of the inspiratory air in
case of spontaneous respiration. Set the oxygen flow should be set to between
2 and 4 l/min, and the free end of the oxygen reservoir should be held as tightly
as possible against the patient’s head.
The oxygen concentration will be very close to
100 %
at the end of the tube.
Depending on the distance between the oxygen reservoir and the patient’s head,
there will be significantly more or less inhalation of atmospheric air, and thus
lower oxygen concentrations should be expected.

8. Cleaning-disinfection-sterilisation
Clean – disinfect – sterilize the complete resuscitator thoroughly after each
patient use or if used in a patient/environment with infectious diseases.
8.1 Disassembly

The resuscitator must always be disassembled for cleaning as shown.
Adult (6.1), Peadiatric (6.2), Neonate (6.3)
CAUTION
Do not try to disconnect the patient connector from the patient valve
(permanent snap fit).
Do not disassemble parts further than shown.
The bag connector should not be detached from the bag during
the cleaning and sterilisation procedure.
