A question about my Inogen one G5
I often times I get winded when walking with my One G5 set to 4 L/M, as the DR. ordered. MY question for other users is how long in the Blast of air you get from yours last. Mine is one second at the max. I do see how this could possibly deliver 4 L/M. I balled Inogen and they just danced around my question and couldn't answer.
Please comment if you can,
Kevin
Great question. Sorry you did not get an answer to your question by the Inogen representative. You would think they, of all people, would be able to answer your question. I personally would love to hear what they have to say, if and when you do hear back from them. That said, I do have something to say about your question -- and this is just my opinion of course based on years of experience working in the COPD community, both as a health blogger and respiratory therapist. I would imagine that these devices are well tested, considering they are FDA approved for use by COPD patients at home. I actually talked with a person who created a medical product that had to be approved by the FDA. And he said that the FDA requires lots of studies proving that the product not only does exactly what the company claims, but also that the product is durable and will last. So, I would imagine this is also true for all product that provide oxygen (a drug) to patients, including your One G5. Likewise, your own oxygen provider (the company that provides you with your oxygen equipment) can test (double check) your equipment to make sure your device is giving you 4LPM as prescribed. And this should give you reassurance that the product is working. What do you think? John. copd.net community moderator.
Hi senrab, and thanks for your post. I see my colleague, , has already provided an excellent response based on his training and experience.
Like, John, I am also disappointed that Inogen did not respond to your inquiry. If you have the time and patience, you may want to call back and speak with someone else - they certainly have folks on staff who can address your concerns.
If you do, please do check back and let us know how this turns out for you.
All the best,

I will contact Inogen Monday Morning to get more info on this but I think I may have found the problem, I "RTFM!", read the F* manual. On page 24 of the One G5 manual, there is a table that lists flow settings .vs. Breaths/min. Under the flowing settings, there is an unlabeled number and I have no idea what it means. However, at the bottom of the table, it lists the Total Volume per Minute, ml/min! The total for a flow setting of 4 is 840 ml/min and not 4 L/m. If I understand this info I'm getting ~~1/4 the O2 I thought I was getting???
Confused,
KevinHi senrab (Kevin), and thanks for your reply and further explanation. I understand what you are saying/asking but, without the manual, it is difficult for me to figure out what is being said by Inogen. I did spend some time trying to locate the information and a manual online with no luck. I had thought a setting of '4' would mean 4 liters per minute as well. But, if a setting of 4 actually means 840 ml/min, that is somewhat confusing for sure. Flow rates of oxygen tend to be referred to in units as 'liters per minute', not milliliters per minute!
I would encourage you to reach out to them (as you said), on Monday morning to get a straight answer on how the concentrator delivers oxygen.
Please do check back and let us know what you find out.
I am going to tagand Lyn Harper - perhaps they are familiar with this particular oxygen concentrator and can shed some light on this concern.
Wishing you well,
