Oxygen therapy treatment of labored breathing and different breathing diseases has been in place for a while now. Different devices have been used for that. But modern technology made these devices for oxygen therapy smaller and easier to use. So, most of the devices that provide oxygen are not those huge machines that were applied before. Today only two types of oxygen for therapy are used - compressed oxygen and liquid oxygen. You might have seen special cylinders with breathing masks attached to them. These are special containers for compressed oxygen. Such devices have all the necessary valves, indicators and tubing to provide the needed dosage of oxygen for oxygen therapy treatment. Another way of storing oxygen for therapy purposes is chilling it to low temperatures and at these temperatures oxygen turns into liquid form which occupies less space. So, this liquid oxygen can be stored in smaller vessels. This method has a disadvantage. The problem is that liquid form of oxygen cannot be stored for a long time because the gas is fast to evaporate. Most of the modifications of cylinders for compressed oxygen and vessels for liquid oxygen can be easily used at home. And these days more and more people are using oxygen therapy treatment right at their homes. At hospitals and homes another sort of oxygen devices can also be used. It is called "Oxygen Concentrator". These devices are usually big (and, in fact, pretty noisy), so they are intended for stationary use (some of the latest models are mobile). In concentrator the oxygen is separated right from the air. That means that there is no need to supply this device with oxygen like in case of compressed oxygen devices. And to deliver oxygen to the patient oxygen mask is usually used. It provides an intense (but easily regulated) oxygen flow and it is pretty easy to use the mask, so all you need is to apply it to the face and start breathing. And technologies of oxygen therapy are still being developed and new usages of oxygen and new methods of oxygen therapy treatment are being introduced. For example, a pretty effective and very promising method of hyperbaric oxygen therapy appears to be the method which combines the effect of higher atmospheric pressure and increased concentration of oxygen. This mixture is a sure way of treating such problems as decompression sickness. The experiments that have been conducted lately demonstrated that hyperbaric therapy can be used for treatment of numerous diseases. The techniques and effects of hyperbaric oxygen therapy are still being tested and special research works are being performed to improve healing techniques that are already in use and to develop new methods of treatment. Using another combination, the combination of oxygen and its another form, ozone, it is possible to get another method of therapy that is in use now - oxygen ozone therapy. Ozone has always been known for its antimicrobic action which makes this technique suitable for treatment of different diseases even of infectious ones.
