Pneumatic nebulization and O
2
concentration
Remark
When the O
2
supply is not connected, the pneumatic nebulizer
cannot be started.
The nebulizer is operated with air at a set oxygen concentration (FiO
2
) ≤ 60 %
and with oxygen at a concentration > 60%.
The oxygen concentration of the inspiratory flow and the byflow are adapted
such that the set oxygen concentration (FiO
2
) at the Y-connector is guaranteed
within a tolerance range of +/- 4%.
If the pneumatic nebulizer is switched on, the Instant View window no longer
shows the measured FiO
2
value but rather the value calculated at the Y-connector.
In this case the colour coding of the display field is hidden.
