During a normal field maintenance visit, the technician may elect to turn off the
concentrator for approximately 30 minutes. If the patient requires oxygen during
this period, Inogen recommends making arrangements to bring an extra oxygen
supply (such as a supplemental Inogen One G3 Concentrator).
3.1.4. 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, batteries, 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 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.
3.1.5. Product Filter
This filter is intended to protect the user from small particles in the product gas flow.
The Inogen One G3 includes a product filter, conveniently located behind the removable
cannula nozzle fitting. Inogen suggests that this filter be replaced between patients.
