4.6 Increasing the oxygen concentration
•
Intubation
•
Press the red ring on the COMBIBAG relief valve
downwards (pressure limit 60 mbar/cm H
•
Even with ventilation via an endotrachel tube, one
should aim for a pressure limit of 20 mbar/cm H
in order to limit the drop in the heart circulation time
caused by increase in resistance in the pulmonary
circulation.
In emergency situations, oxygen concentrations above
that in the ambient air (21 vol. %), or even 100% oxy-
gen may be indicated, since oxygen deficiency often
has to be reckoned with at the first supply phase. Any
oxygen concentration can be administered with the
COMBIBAG resuscitator. Oxygen concentrations up
to 48% can be administered directly via the oxygen
socket on the intake connection. If a higher concentra-
tion of oxygen is to be administered, an oxygen reser-
voir or a demand valve can be used.
Connect corrugated hose
•
Fit the oxygen reservoir into the cone on the intake
socket and
•
push the oxygen connecting tube onto the connec-
tor at the end of the corrugated hose.
Connect demand valve
•
Attach demand valve with appropriate adapter
WM 22169.
•
Follow the instructions for use for the demand valve.
