The most recent technological advancements have brought the developments of some portable oxygen concentrators that are bringing a whole new concept of freedom to oxygen users. A few revolutionary machines have been released over the past few years, and some of the older models have been updated with the new expectations that come along with the release of new oxygen technologies. Of course, not every oxygen therapy product will be right for you. You'll need to make sure the POC can meet all of your needs.

Here are some questions you need to be asking when shopping for a portable oxygen concentrator.

1. Will a POC imeet your daily oxygen needs?
Your mobile concentrator needs to be able to provide you with the oxygen dosage you need at all times, no matter where you are or what you're doing. Your oxygen needs will be different when you're physically active when you're sleeping and or sitting and watching television. The POC needs to be able to detect the changes in your breath rate and compensate accordingly.

There are two types of oxygen settings that come with portable models – pulse dose, and continuous flow oxygen. All POCs that have continuous flow settings, also have pulse dose settings, as well. As of right now, the highest continuous flow setting in a moible unit is 3 LPM (liters per minute).

You will need to make sure that whatever portable oxygen concentrator you get has the dosage setting you need, with a high enough breath rate. The maximum breath rate and dosage volume should exceed what you would normally need, to make sure you'll never run short. It should have a good oxygen reserve, so when your breath rate goes up, the dosage will go up to meet it. Breath rate is measured in breaths per minute (BPM). If you need a low dose or a low pulse dose of oxygen, you'll be able to take advantage of the smaller portable oxygen concentrators. If you need 5 LPM of continuous oxygen, you won't be able to use any of the continuous flow portable models that are currently on the market.

2. Is a portable oxygen concentrator truly portable?
By definition, a portable unit needs to be light enough so that you don't feel burdened while carrying it around anywhere you need to go. You have to take into consideration the weight of the unit, including the weight of the battery and accessories you will be carrying around along with it. You might also need to bring along extra batteries and power supplies. You should always expect to add a few extra pounds for the additional batteries if you are out and about all day.

3.What type of maintenance is needed on my portable oxygen concentrator?
Just like any other machine, POCs require regular maintenance and service to ensure it operates correctly and run smoothly. Usually, any maintenance is minimal.

4. Is there a warranty on my unit?
Most manufacturers include a 3-year warranty on new portable concentrators, and each battery usually has a warranty for 1 year. Accessories warranties usually vary from 30 to 90 days and up to 1-year in some cases.
