• If continued resistance to insufflation is encountered, check the airway for obstruction
and re-position the patient, to ensure an open airway�
• If the patient vomits during ventilation; immediately remove the resuscitator to
clear the patient's airway and expel the vomit from the resuscitator by shaking and
compressing it forcefully and fast several times before resuming ventilation� In the
case of excessive amount of vomitus obstructing the air flow, the patient valve may be
disassembled and cleaned� For details on dis- and reassembly of the patient valve refer
to illustrations
5.5
and
6.1
�
• If connecting external devices to the resuscitator, make sure to test for functionality and
consult the instructions for use accompanying these external devices�
Manometer port
The Ambu Disposable Pressure Manometer or a third-party pressure gauge can be
attached to the manometer port, situated on the top of the patient valve� Remove the cap
and attach the manometer/pressure gauge

�
Pressure-limiting valve
The pressure-limiting valve is set to open at 40 cmH₂O (4�0 kPa)�
If medical and professional assessment indicates that a pressure above 40 cmH₂O is
required, the pressure-limiting valve can be overridden by pressing the override cap onto
the valve

�
Alternatively, the pressure-limiting valve can be overridden by placing the index finger on
the blue button while squeezing the bag�
Oxygen administration
Administer oxygen according to the medical indication�
Figure 4 shows calculated delivered oxygen percentages which can be obtained with
different ventilation volumes and frequencies at different gas flow rates referring to Oval
Plus Silicone Resuscitator Adult

and Oval
Plus Silicone Resuscitator Neonate

, respectively�
4.4. Reprocessing: cleaning, disinfection, sterilization
Follow these reprocessing instructions after each use to reduce the risk of cross-contamination�
Disassembly
Before reprocessing, manually disassemble the resuscitator into individual components to
the level shown in
5.1
5.2
5.3
to make surfaces accessible to cleaning�
Follow the disassembly method shown in
5.4
5.5
and
5.6
�
Keep components from the same device together during reprocessing and keep track
of the number of times each resuscitator has been processed to avoid reassembly of
components with different durability�
