2.2 Warning
WARNING
Lack of an alternative ventilation method, such as a self-priming operator-powered
resuscitator (according to ISO 10651-4), may result in patient death if the ventilator
fails. Always have a separate manual breathing bag handy.

WARNING
Do not operate the device outside the specified ambient conditions (see chapter 1.9).
Otherwise, device functionality may be impaired.
WARNING
The ventilator suctions ambient air to create compressed air. It must therefore never
be covered during operation or placed so that its operation or performance is impaired.
Failure to comply may result in device failure or damage and therefore pose a risk to
the patient.
WARNING
If the ventilator is to be operated with additional O
2
, the O
2
supply pressure must be
2.8 – 6 bar (see chapter 1.9).
WARNING
The displayed O
2
concentration is not a measurement. Instead, the gas concentration is
calculated from the flow rates.
