    I am a disabled vet and have serious back and head injuries from military. Also developed COPD from smoking, constant diesel fumes, and working in toxic chemical after service!

    I have been put on O2 24/7 permanently! Started with pulling bottle around on two wheels and then the VA gave me the new Inogen One G4 and that is the best thing they ever did for me! I don't mind going places with my wife or going out to eat! This machine is great! I have a shoulder strap or the backpack to carry, so it's easy and is on battery, house plug in, or car lighter plug in! Amazing!!!

  • When I became ill, it was very unexpected and sudden. I became oxygen dependent. I went from employed, independent to attached to a concentrator. I went into a deep depression.

    When I became ill, it was very unexpected and sudden. I became oxygen dependent. I went from employed, independent to attached to a concentrator. I went into a deep depression.  I then saw the ad on TV about the Inogen One. I called. That was the best thing I did since this has happened. I have my independence back! Thank you Inogen.

    The use of my Inogen Oxygen Concentrator has allowed me to continue doing our shopping and routine trips to the doctor, and the dentist. Also, we are active in church activities and I am able to sing in the choir with no difficulty.We recently flew to the east coast and I was able to breathe comfortably even though the aircraft cabin was pressurized at 7000 ft elevation. Without my Inogen G4, I would find my activities to be limited.

    Having a home in both Michigan and Florida is why we chose Inogen. With the in home concentrator being so much smaller than most and able to fit in a carry on rollabout, it has allowed us the flexibility for traveling either by car or plane.No need to worry or wait for delivery of my oxygen and knowing it is always with me for use with my bipap. The portable unit is great for short trips and allows me to be independent. Medicare covered the cost of the in home and G3 unit. I purchased the G4 to have a lighter option and have more battery power for long days. Baseball tournament that lasted all day and no need to go to the car to charge.

Inogen One Portable Oxygen Concentrator
USES: The Inogen One Portable Oxygen Concentrator provides a high concentration of supplemental oxygen to patients requiring respiratory therapy on a prescriptive basis. It may be used in home, institution, vehicle and various mobile environments.

DO NOT USE IF: This device is not intended to be used in any way other than described in the indications for use. Do not use in parallel or series with other oxygen concentrators or oxygen therapy devices. This device is to be used as an oxygen supplement and is not intended to be life sustaining or life supporting. ONLY use this product if the patient is capable of spontaneous breath, able to inhale and exhale without the use of a machine. The conserving, or pulse dose, oxygen delivery technique used by this device is contraindicated in persons whose breathing during normal resting would be unable to trigger the device. Proper device triggering, set up and operation must be confirmed by an experienced clinician or other respiratory professional. Not for use by tracheotomized patients. Use of this device has not been studied in pediatric populations. Consult your physician before using the product for pediatric patients.

WARNINGS: The device produces enriched oxygen gas, which accelerates combustion. Do not allow smoking or open flames within 2m (6.56ft) of this device while in use. If you feel ill or uncomfortable, or if the concentrator does not signal an oxygen pulse and you are unable to hear and/or feel the oxygen pulse, consult your equipment provider and/or your physician immediately. If you are unable to communicate discomfort, you may require additional monitoring and or a distributed alarm system to convey the information about the discomfort and or the medical urgency to your responsible caregiver to avoid harm. Use only spare parts recommended by the manufacturer to ensure proper function and to avoid the risk of fire and burns. To avoid danger of choking or strangulation hazard, keep cords away from children and pets.

TALK TO YOUR HEALTH CARE PROVIDER: The oxygen flow setting must be determined and recorded for each patient individually by the prescriber, including the configuration of the device, its parts and the accessories. It is the responsibility of the patient to periodically reassess the setting(s) of the therapy for effectiveness. The proper placement and positioning of the prongs of the nasal cannula in the nose is critical for oxygen to be delivered.

Inogen At Home Stationary Oxygen Concentrator
USES: The Inogen At Home Oxygen Concentrator is used on a prescriptive basis by patients 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.

DO NOT USE IF: This device is not intended to be used in any way other than described in the indications for use. This device is to be used as an oxygen supplement and is not intended to be life sustaining or life supporting. ONLY use this product if the patient is capable of spontaneous breath, able to inhale and exhale without the use of a machine. Not for pediatric use. Not for use by tracheotomized patients.

WARNINGS: The device produces enriched oxygen gas, which accelerates combustion. Do not use the device when smoking or near open flame, matches, petroleum, oil, grease, solvents, radiant heaters, aerosols, etc. If you feel ill or uncomfortable, consult your equipment provider and/or your physician immediately. If you are unable to communicate discomfort, you may require additional monitoring and or a distributed alarm system to convey the information about the discomfort and or the medical urgency to your responsible caregiver to avoid harm.
