6 Operation
6.7 Supplying oxygen
6.7.1 Setting oxygen concentration
Requirements • The oxygen supply is connected (see “4.4 Connecting the
oxygen supply”, page 41).
• The type of supply gas (O
2
100 % or O
2
93 %) is set in the
operator menu (see “9.3 Device settings”, page 107).
• The device is switched on (see “6.1 Switching on the device”,
page 55).
• Ventilation has been started (see “6.3 Starting ventilation”,
page 57).
Therapy disrupted by supply of excessively high flow!
If the flow exceeds the maximum permitted value of
15 l/min, the pressure relief valve might unintentionally open
during inspiration and place the therapy at risk. This might injure
the patient.
Supply oxygen only at a maximum flow of
15 l/min.
Inadequate oxygen concentration due to leaks during
ventilation!
Leaks during ventilation may lead to the concentration of oxygen
administered in the respiratory gas being reduced. This might
injure the patient.
Check that the mask or tracheal tube is correctly positioned.
Note measured value O
2
i for assessing ventilation. Also correct
oxygen supply if necessary.
Use suitable external patient monitoring methods.
If you want an oxygen concentration of 100 %, use the
administered minute volume (MVi) as a guide.
