Setting the O2 concentration
 Set the O2 flow at the O2 concentrator as di-
rected by the doctor: max. 10 L/min at an O
2
pressure of max. 0.5 bar (500 hPa or 7.25 psi).
 In ventilation intervals stop the O
2 feed to pre-
vent escape of excess oxygen.
The O
2 concentration reaching the patient is influ-
enced by the following factors:
– Breathing circuit in use
–The O
2 concentration delivered by the O2 con-
centrator used
– Specified O
2 flow at the O2 concentrator (LPO
flow)
– Applied minute volume (MV)
– Mean airway pressure Pmean
The O
2 concentration for the patient at specified
ventilation parameters is only set via the flow con-
trol at the O
2 concentrator. Use diagrams to esti-
mate the flow control, see page 76.
The use of an external O
2 monitor to measure the
current O
2 concentration simplifies the process of
setting the O
2 concentrator exactly to the desired
O2 concentration.
