requiring supplemental oxygen. It supplies a high concentration of oxygen and is used
with a nasal cannula to channel oxygen from the concentrator to the patient. The Inogen
One® G4 may be used in home, institution, vehicle and various mobile environments.
CAUTION
USA Federal law restricts this device to sale by or on the order of a
physician. May also be applicable in other countries.
CAUTION
Nasal cannula should be rated for 3 liters per minute (e.g. Salter Labs
16SOFT) to ensure proper patient usage and oxygen delivery.
WARNING
Availability of an alternate source of oxygen is recommended in case of
power outage or mechanical failure. Consult your equipment provider for
type of back-up system recommended.
CAUTION
It is the responsibility of the patient to make back-up arrangements for
alternative oxygen supply when traveling; Inogen assumes no liability for
persons choosing not to adhere to manufacturer recommendations.
