4 Basic principle
1. Basic principle
1.1 Purpose
The COMBIBAG is for the manual ventilation of children (from a body weight of 10 kg) and adults via a
face mask or endotracheal tube. The respiratory air
can be enriched with oxygen.
1.2 Function
On squeezing the bag, a volume of gas (air, air enriched with oxygen or pure oxygen) is forced through
the resuscitation valve into the patient’s lungs.
As soon as the elastic bag is released, it fills up again
via the inlet valve, resuming its former shape. At the
same time, the diaphragm in the patient valve closes
the connection to the bag and opens the expiration
passage. The patient then exhales into the atmosphere
and expired air cannot flow back into the bag. In case
of spontaneous breathing, the patient can breathe independantly in and out via the expiration passage.

1.3 Special Features of the COMBIBAG
COMBIBAG, the first manual resuscitator
with segmental division for adults and children.
Hitherto, at least 2 resuscitation bags were required to
ventilate patients of all age groups, a child resuscitation bag and a large adult resuscitation bag.
Now the special design featuring the COMBIBAG
covers both functions. The bag is divided into two segments (one large and one small) by two longitudinal
troughs, marked with appropriate symbols. The tidal
volume required can be obtained by squeezing the
adult or child segment:
• up to 500 ml in child ventilation
• 500 - 1200 ml in adult ventilation.
The usual, separate child bag becomes unnecessary.
The principle of “two bags in one” is extremely economical and saves space in each emergency kit.
COMBIBAG, the first manual resuscitator
with a 2-stage safety valve.
By now, pressure relief as a function of the variable
risks present in ventilation via face mask or endotracheal tube remained unsolved.
The majority of manual resuscitators only have a pressure limit at 50 - 60 mbar (50 - 60 cm H2O), a reasonable limit adapted to healthy lung conditions.
With use of manual resuscitators and face mask ventilation in inexperienced hands, however, there is always the risk that anxiety of the administrator and the
eager trial to produce very effective ventilation may
lead to an inflation of the stomach at pressures above

6 Basic principle
20 mbar resulting in regurgitation with following apiration. Moreover, there is the risk with ventilation of
children independant from face mask or endotracheal
tube that high ventilation pressures may hurt the lungs.
With the COMBIBAG 2-stage safety valve it is now
possible to set a pressure limit:
• of 20 mbar (20 cm H
2
O) for mask resuscitation
child ventilation and
• one of 60 mbar (60 cm H2O) for resuscitation via
an endotracheal tube with adults.

2. Description of the resuscitator
2.1 COMBIBAG components
The COMBIBAG resuscitator for adults and children
consists of 4 working parts:
Patient valve
The patient valve consists of:
• the valve body with bag adapter,
• inspiration cone for connection of the mask or endotracheal tube connector(diameter 22/15 mm)
• valve diaphragm for separating inspiration and
expiration
• safety valve (pressure-relief valve).
Safety valve
The safety valve (pressure-relief valve) consists of:
• the valve body with valve fittings and
• white pressure marks (20 and 60 mbar/cm H2O)
and the red valve ring with white arrows and the
figures 20 and 60.
Because the safety valve can be accurately adjusted
only by the manufacturer WEINMANN, replacement
is possible only with delivery of a complete unit. Removal of the safety valve is not permitted.

8 Description of the resuscitator
Squeeze bag
The squeeze bag (compressable unit) is divided into
segments by two asymmetrical troughs, marked with
pictograms (symbol of a child and of an adult), and
creates the gas volume required on squeezing the corresponding segment.
Intake valve
The intake valve consists of:
• valve intake port inner part with connecting socket
for oxygen enrichment
• intake port cover
• valve plate to allow the inlet of fresh gas and forming a seal when the bag is squeezed
• silicone ring for hanging up the COMBIBAG.

3. Safety instructions
For your own safety, the safety of your patients, and to
comply with the requirements of EU Directive 93/42
EEC, please observe the following points:
• Carefully observe the operating instructions, which
is part of the instrument and must be available all
the time.
• The detailed knowledge and attention of this operating instructions are the basis for proper use of the
COMBIBAG. The instrument is just determined for
the field of use stated.
• Malfunctions and a lack of biocompatibility may result if third-party articles are used. Please bear in
mind that in these cases any warranty entitlement
and liability shall lapse where the accessories recommended in the instructions for use or original
spare parts are not utilised.
• To prevent infection or bacterial contamination,
please observe section “5. Hygienic preparation”
on page 15.
•
Warning: The unit takes in ambient air so it may not
be used in a toxic atmosphere.
• The unit is only allowed to be used by experienced
personell trained in resuscitation and well acquainted with the instrument.
• In operation with oxygen it is imperative that smoking and open fire around the oxygen fittings is strictly prohibited.
• Oil and grease should not be used in conjunction
with the resuscitation unit.
• Not for infants and children with a body weight
below 10 kg.
• More copies of this operating instructions are available from the manufacturer WEINMANN.
