Portable Oxygen Concentrators
A POC or portable oxygen concentrator is really a device, which is found in order to provide an individual with oxygen therapy that exceeds the concentration of atmospheric air. They're similar in structure and use to home-based oxygen concentrator but are smaller and, therefore, more portable. This enables for patients to travel and move with the assurance they have oxygen therapy nearby should it be required. These devices are small enough to be placed in the car and also have also recently become FAA approved.
The Development of Portable Oxygen Concentrators
POCs have been designed for several years but the past models have already been excessively bulky rather than nearly as reliable as those currently in the marketplace. 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 utilizing a house outlet or in the automobile utilizing a vehicle adapter. They can also be used through the use of batteries so that they can be used when no outlet is available.
How Does these devices Function?
The technology that's found in the portable oxygen concentrator is the same, that 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 machine pressurizes the air utilizing a chemical filter system, that is used as a sieve for the gas molecules. The filter 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. Section of the oxygen is used in this manner, while a percentage of the gas is reused in the next cycle. Through the use of this process, the filtering system is able to produce high quality concentrated oxygen of approximately 96% concentration.
The most recent types of POCs are powered using electricity supplies or battery packs which permit the patient to remain free from the application of cylinders or other heavier options that could restrict movement. Nearly Additional info are powered by a pulse delivery system, that allows for maximum oxygen purity.

The majority of POCs are quite light and small and this can be achieved because of the usage of an on-demand system. This enables the portable oxygen concentrator to be made up of smaller pieces than a home oxygen system. The fact that the average person only inhales oxygen, the on-demand device allows for the patient to receive all the oxygen they require and no more, thereby eliminating the chance that unnecessary oxygen will be wasted.
Nearly all on-demand systems have a variety of settings that to push out 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 required during inhalation rather than exhalation.
This technology is accomplished with the use of boluses that may vary depending on the breathing rate of the patient. That 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.
Although some physicians will recommend a continuous system as opposed to an on-demand system during sleep, the new devices are located to be in the same way effective as nighttime oxygen therapy. However, they should not be utilized in individuals who have problems with sleep apnea.
