Manometer port (Only applicable for Ambu Mark IV Baby)
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 (Only applicable for Ambu Mark IV Baby)
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 medical indication.
The figure 4 shows calculated delivered oxygen percentages which can be obtained with
different ventilation volumes and frequencies at different gas flow rates referring to Mark
IV Adult and Mark IV Baby , respectively.

for Mark IV Baby
Table 1: Recommended reprocessing procedures.
Product testing has shown that the Ambu Mark IV resuscitator is fully functional after 30
full reprocessing cycles, as listed in Table 1, with the exception of the oxygen reservoir bag,
which can be sterilized maximum 15 times or chemically disinfected maximum 30 times.
It is the user's responsibility to qualify any deviations from the recommended cycles and
methods of processing, and to monitor that the recommended number of reprocessing
cycles is not exceeded.
Always perform a test of functionality prior to each use (see section 4.2.2.)
