A POC or portable oxygen concentrator is a device, which is used in order to provide a patient 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 that 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 however the past models have already been excessively bulky and not nearly as reliable as those currently out there These older models were also not permissible on aircraft Since the year 2000, the reliability of the devices has increased in both practicality and efficiency They are able to be charged utilizing a house outlet or in the automobile using a vehicle adapter They are able to 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 is used 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 device pressurizes the air using a chemical filter system, which is used as a sieve for the gas molecules The filter is composed of silicate granules, or Zeolite, which removes the nitrogen from the air This serves to concentrate the oxygen, which is then inhaled by the individual Part of the oxygen is used this way, while a share of the gas is reused within the next cycle Through the use of this technique, the filtering system can produce top quality concentrated oxygen of around 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 utilization of cylinders or other heavier options that could restrict movement Nearly all these devices are powered by a pulse delivery system, that allows for maximum oxygen purity Great things about On-Demand POCs The majority of POCs are quite light and small which is often achieved due to the usage of an on-demand system This allows the portable oxygen concentrator to be composed of smaller pieces than a home oxygen system The fact that the individual only inhales oxygen, the on-demand device allows for the patient to get all the oxygen they require no more, thereby eliminating the chance that unnecessary oxygen will be wasted The majority of on-demand systems have a variety of settings that release a certain amount of liters per oxygen each minute Using the correct amount of oxygen prevents the waste of oxygen when the patient exhales as oxygen is required during inhalation and not exhalation https//wwwinogencom/resources/oxygen-tanks/ is accomplished with the use of boluses that can vary with respect to the breathing rate of the individual That is particularly useful when sleeping when the rate naturally slows A machine that utilizes a variable bolus system can detect the slowed rate of breathing, in order that it releases the required level 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 during sleep, the new devices are located to be just as effective as nighttime oxygen therapy However, they ought to not be used in individuals who have problems with sleep apnea
