To get an appropriate POC,l you really have to know what you're doing, and you can't depend on the vender to tell you exactly what you need to know, nor can you depend on your doc to tell you because most of the time, docs, including pulmos don't know anything about portable O2. So unless you get really lucky and find an honest vender who really knows his product and understands how it works, you won't be getting good information from them. Here are four resources you should read or view very carefully before you go off to purchase something:

Excellent webinar by Bob McCoy on delivery systems, titrating, and all things O2

AARC’s analysis of Portable O2 Concentrators

Brian Tiep on oximeter usage by patients

Ryan Diesem’s analysis of POC’s

Another good resource is the Pulmonary Paper, which you can get on line or by subsrciption in the mail. The latest issue has another great report by Ryan Deisem about currently available POCs. One of the major things to remember is that you will be better off if you try the machine before you purchase it.

I have been on 02 for years and I have a Inogen and liquid oxygen tanks. I use the liquid tanks on my back when I work my horses and use the Inogen at other times. The liquid tank is smaller and it does not get hot....the inogen weighs abvout 7 pounds and it gets warm as it runs which is not good when you are outdoors working on a horse farm in Texas in the summer!

I always keep it plugged in while driving and have a full charge when I arrive enen using it the whole time

The battery time is based on your needs. I am at a 5 or 6 lpm so my batteries do not last as long. The big battery you get 9 out of, I get 4 at a high setting. But, the G2 unit also charges from the car battery so when driving, even using it to breathe, it puts more charge on the battery than is used. Love it for traveling.

I purchased a portable unit for my use as medicare only pays for my large in house unit. I can use the unit with my 8 hour battery or run the unit on electricity. There are several good units available and I found my unit and purchased it off the internet. Hope this gives you some an idea
