6 Operation
Example:
If you are also supplying oxygen at 5 l/min at a displayed MVi of
5 l/min, this will result in an inspiratory oxygen concentration of
100 %.
If you want a lower concentration, set a lower flow on the oxygen
supply until the device displays the desired oxygen concentration.
1. Set the flow at the oxygen supply.
The device indicates the measured oxygen concentration in the
display.
2. Read off the oxygen concentration from the display.
3. If necessary: Adjust the oxygen concentration.
Result The oxygen concentration has been set.
