I love this quiet little machine
I love this quiet little machine. It takes up so little room, is easy to travel with and does the job of supplying me with oxygen at night while I sleep.

Inogen has helped me live a fuller life, Before Inogen I did not go out much because the tanks were too heavy to carry and shop. I absolutely love my Inogen. The people working there have been wonderful and kind

Unit is so much easier to utilize compared to the tanks. My only concern is the nasal irritation that occurs with the constant air flow.

I love both of my Inogen O2 machines
I love both of my Inogen O2 machines. The bedside one is a wonderful apparatus......I use it with my Bi Pap machine at night, and also when I’m resting or reading in bed. I love my 10 hour carry bag O2 machine because it lasts a long time and it’s easy to carry in my walker, or attach to the handle of my electric wheel chair. It is wonderful not to have to drag around the cumbersome O2 tanks. It costs $ 11.00 per day for one small tank here.
My machines will pay for themselves in a couple of years. I feel so fortunate to have these
marvellous machines!
Andy was so helpful to us; he explained everything to us ( my husband and I ). Thank you so
very much, Inogen !!

I am very pleased with my Inogen Oxygen. It's very light weight and easy to manage. There is no comparison to the one I was issued! It making moving around not nearly as burdensome as the issue I was given by Medicare.

Confidence to leave home
We purchased an Inogen for my 94 year-old father who has severe COPD. There is nothing more heart-warming than to see the confidence the Inogen has given him to be able to leave his home and not worry about breathing! Your company has done an outstanding job of answering all our questions and making sure that we were taken care of. Best purchase ever!

It has been great being free from the tanks. I'm able to do more and not be a prisoner in my own home. I purchased an extra battery and one of them had to be replaced. In oven replaced it free of charge! It has since become defective again and it is being replaced in the same manner.

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 pediatric use. Not for use by tracheotomized 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.
