3.2. Maintenance by the Patient
3.2.1. Cannula Replacement
The nasal cannula should be replaced on a regular basis. A single lumen cannula of 4
to 100 feet in length must be used. Inogen has certified its performance data with the
Salter Laboratories 16SOFT cannula.
CAUTION
Do not use total cannula tubing length exceeding 100 feet with the Inogen
At Home unless proper saturation has been verified by a clinician.
3.2.2. Particle Filter Cleaning and Replacement
On the side of the Inogen At Home, ambient air passes through a particle filter that
removes dust fragments. This particle filter must be cleaned on a weekly basis to
CAUTION
Do not leave the column exposed after the dust caps are removed; it
should be inserted into the concentrator as soon as the dust caps have
been removed to minimize environmental exposure and maximize
lifespan.
NOTE
Column change instructions are only to be used when maintenance is
required. Column should only be removed during this maintenance
procedure.
