Low Pressure Oxygen (LPO)
Safety information for LPO
105
WARNING
Risk of infection and insufficient O2 supply
If the oxygen source is not suitable for direct
supply to the patient, there is a risk of infec-
tion and the LPO supply may fail.
Only connect oxygen sources that are ap-
proved for medical use and that meet the fol-
lowing conditions:
–O2 flow: max. 10 L/min
–O2 pressure: max. 0.5 bar (500 hPa or
7.25 psi)
WARNING
Risk of fire
Due to oxygen enrichment in the ambient air,
the medical device can ignite.
Ensure sufficient ventilation at the rear of the
device.
Do not use any oxygen source that delivers a
flow exceeding 10 L/min.
If the device is not in ventilation mode, switch
off the oxygen source, e.g., O2 concentrator.
WARNING
Risk of patient injury
Moist oxygen may affect the function of the
device.
Only operate an O
2 concentrator without hu-
midifier. Drain or remove a humidity system
on the O2 concentrator before use.
