Autoclaving: Use standard autoclaving equipment adjusted for 134 °C (273 °F) for
resuscitator parts according to the table above.
Sterilisation by gravity steam autoclave running a full cycle at 134 degrees Celsius for
10 minutes at a standard pressure and then dry 30 minutes.
For drying and cooling leave the parts to dry and/or cool completely before reassem-
bling the resuscitator.
Note: that it is the user's responsibility to qualify any deviations from the recom-
mended method of processing
8.6 Inspection of parts
After cleaning, disinfecting and/or sterilising carefully inspect all parts for damage
and residuals or excessive wear and replace if necessary. Some methods may cause
discoloration of rubber parts without impact on their lifetime. In case of material
deterioration e.g. cracking, the parts should be replaced.
When inserting the valve housing of the inlet valve: Make sure that the bag opening
seats smoothly against the flange.
When inserting the patient valve disc: Make sure that the butt of the stem is pushed
through the hole in the middle of the patient valve housing.
When mounting the outlet cap (option): Note that the slot of the outlet cap should
face the patient connector.
8.7 Reassembly
Reassemble the parts of the resuscitator as shown in the illustration 
Adult (6.1), Peadiatric (6.2), Neonate (6.3)
9. Test of function 
Resuscitator
Close the pressure-limiting valve with the override cap (This only applies to the
version with pressure limiting valve) and close the patient connector with the thumb
(7.1). Briskly squeeze the bag. The resuscitator shall offer resistance to the squeeze.
Open the pressure-limiting valve by opening the override cap or by removing the
finger and repeating the procedure. The pressure limiting valve should now be
activated and it should be possible to hear the expiratory flow from the valve.
Squeeze and release the resuscitator a few times to ensure that air is moving through
the valve system and out of the patient valve. (7.2)
Note: As the valve plates are moving during functional test or during ventilation a
slight sound may appear. This does not compromise the functionality of the resuscitator.
Oxygen reservoir bag
Supply a gas flow of 5 l/min to the oxygen bag. Check that the reservoir fills.
If not, check the integrity of the two valve shutters or for a torn reservoir.
Oxygen reservoir tube
Supply a gas flow of 10 l/min to the oxygen tube. Check that the oxygen flows out at
the end of the reservoir tube. If not, check for a blocked oxygen tube.
10. Service
The resuscitator requires no scheduled maintenance other than regular cleaning,
inspection and testing.
