Portable Oxygen Concentrators
A POC or portable oxygen concentrator is a device, which is found in order to provide an individual with oxygen therapy that exceeds the concentration of atmospheric air. They are similar in structure and use to home-based oxygen concentrator but are smaller and, therefore, more portable. This allows for patients to visit and move with the assurance they have oxygen therapy nearby should it be needed. These devices are small enough to be put into the car and have also recently become FAA approved.
The Development of Portable Oxygen Concentrators
POCs have been designed for several years but the past models have been excessively bulky rather than nearly as reliable as those currently out there. These older models were also not permissible on aircraft. Because the year 2000, the reliability of the devices has increased in both practicality and efficiency. They could be charged using a house outlet or in the car using a vehicle adapter. They can also be used by using batteries so that they can be utilized when no outlet is available.
How Does the Device Function?
The technology that's used in the portable oxygen concentrator is the same, which is used, in home concentrators. Barometric pressurized air contains approximately 21 percent oxygen along with nitrogen and a cocktail of various other gasses. The compressor within the device pressurizes the air utilizing a chemical filter system, that is used as a sieve for the gas molecules. Inogen comprises silicate granules, or Zeolite, which removes the nitrogen from the air. This serves to concentrate the oxygen, that is then inhaled by the patient. The main oxygen is used in this manner, while a share of the gas is reused in the next cycle. By using this process, the filtering system can produce top quality concentrated oxygen of around 96% concentration.
The most recent models of POCs are powered using electricity supplies or battery packs which permit the patient to remain free from the use of cylinders or other heavier options which could restrict movement. Nearly all these devices are powered by a pulse delivery system, that allows for maximum oxygen purity.

The majority of POCs are quite light and small which is often achieved due to the usage of an on-demand system. This enables the portable oxygen concentrator to be composed of smaller pieces when compared to a home oxygen system. The truth that the average person only inhales oxygen, the on-demand device permits the patient to get each of the oxygen that they require and no more, thereby eliminating the chance that unnecessary oxygen will undoubtedly be wasted.
The majority of on-demand systems have a variety of settings that release a certain amount of liters per oxygen for each minute. Using the correct quantity of oxygen prevents the waste of oxygen when the patient exhales as oxygen is only required during inhalation rather than exhalation.
This technology is accomplished by using boluses that may vary depending on breathing rate of the patient. This is particularly useful when sleeping once the rate naturally slows. A machine that utilizes a variable bolus system can detect the slowed rate of breathing, so that it releases the required amount of oxygen at a slower rate to accommodate the longer, slower breaths taken.
Even though some physicians will recommend a continuing system instead of an on-demand system while asleep, the new devices are located to be in the same way effective as nighttime oxygen therapy. However, they ought to not be utilized in individuals who have problems with sleep apnea.
