There are many factors to consider when you start the process of choosing the right type of portable oxygen system. In a very broad sense, the two reasons someone may need one of these units are either for emergency use, or therapeutic treatment.
In hazardous working environments, or in some recreational circumstances, having a source of pure oxygen can be a life saver. For those people with a prescribed medical need, these portable units can offer a new lease of life outside the confines of their home.
If the workplace has conditions where people may, in certain circumstances, need a source of oxygen, health and safety and insurance considerations will dictate what is appropriate. In recreational situations like scuba diving, specialised units will usually be available to cope with the particular challenges of the environment in which they will need to be used.
The decision on which unit to choose, is more of a challenge for those people that have a defined medical condition that dictates the need for a supply of pure oxygen. The options for this application mainly fall into three categories: compressed oxygen cylinders, oxygen concentrators, and liquid oxygen tanks.
Compressed oxygen cylinders are by far the most common choice for the majority of people. The tanks come in different sizes, depending on the requirements of the user. The tanks can be carried around in backpacks, or with harnesses. If a large tank is required, a trolley to wheel the tank around may be the preferred option.
Oxygen concentrators are now becoming more and more popular as they can be smaller and less obtrusive than a large cylinder. These work by taking the pure oxygen from the air, then delivering it in a regular stream to the user. The system is run from a rechargeable ac battery, that's inexpensive and simple to replace if necessary.
For extended periods away from home, a liquid oxygen system could be the best choice of portable oxygen system for you. These hold a large amount of oxygen in either one or two silver containers and can be carried in fashionable backpacks. These systems generally weigh no more than ten pounds, and allow the user to move around and enjoy life away from the home, for longer periods than the other systems are practical for.
Whichever system sounds the like the best option for you, make sure that you consult with your physician first, to avoid making a potentially costly mistake. Also, talk to your insurer to make sure that it's covered while away from the home.
