The portable oxygen concentrator has been in use since around 2000. These devices typically produce less than one LPM of oxygen and use a version of pulse flow or demand flow to deliver oxygen. The way this works is that the oxygen is not constantly flowing, only when the patient is inhaling is the flow working. The only draw back to this type

of device is that there are only a few portable oxygen concentrators that produce at least 3 LPM of continuous flow oxygen. However, with the

demand flow the device is able to either provide higher flows or are able to reduce power consumption. Portable oxygen concentrators typically use electricity from a wall outlet and can also run on batteries.

People who find portable oxygen concentrators of the most use are those who wish to travel. The FAA has approved these devices on commercial airlines, just check to make certain that your brand and model is permitted on a particular airline. While these types of devices are very
