3.1.3. Suggested Materials for Regular Maintenance
To perform regular field maintenance (by a technician) on the Inogen One G4 System,
you may need:
o Inogen One G4 Particle Filter (RP-405)
o Output Filter Replacement Kit (RP-404)
 Includes spanner wrench and two output filters
o Inogen One G4 Column Pair (RP-406)
o Inogen One G4 Batteries (BA-400, BA-408)
o Nasal Cannula (Salter Labs 16SOFT or equivalent)
o External Oxygen Analyzer (such as Salter Labs PrO2 Check)
During a normal field maintenance visit, the technician may elect to turn off
the concentrator for approximately 30 minutes. If the patient requires
NOTE
oxygen during this period, Inogen recommends making arrangements to
bring an extra oxygen supply.
3.1.4. Accessing Information Screen
To check usage from the device, press and hold the mode Button (bell symbol) for 5
seconds while the unit is running normally. The concentrator's display will show the hour
meter, the unit's serial number, and the software version installed on the device.
3.1.5. System Inspection
At the start of any maintenance visit:
1. Be sure to ask the patient if they have experienced any difficulties in operating the
equipment.
2. Be sure to ask the patient if they have observed any malfunctions or changes in
characteristics of the equipment.
3. Visually inspect the device and accessories for cracks or other damage.
4. Feel the sides of the device for vibration and listen for unusual noises, rattles, or
other signs that the device requires service.
Discovery of cracks or other types of external damage may be indicative of
other internal damage that may not be visible. If such external damage is
discovered, be certain to inquire as to how it occurred, and whether any
CAUTION
changes in the device have been noticeable since its occurrence. If you
have any concern over the safety of the device, arrange for equipment
servicing.
