A portable oxygen concentrator is a mobile device that provides oxygen therapy to a patient at substantially higher concentration than the level of ambient air. It enables patients to be breath independently. The POC range covered by intermediacy is small and discreet, uses battery power, but a car can power it. POC are seniors since they have been there five decades. However, seniors were bulky, not reliable and not supposed to be used in airplanes. Nevertheless, over the years, some manufacturers have improved their reliability by producing around 1-6 liters in a minute per oxygen concentrator.You can plug the POC directly into a regular house outlet for home charging. Also, you can connect a POC to a vehicle DC adapter when you want to use it. The technology of the domestic home concentrators is based on the same principle behind this discovery. Air at barometric pressure contains 21% oxygen combined with nitrogen and a mixture of other gases. Inside the device, there is a miniaturized compressor, which pressurizes the air through a system of chemical filters called molecular sieves.
Part of the air produced is delivered to the patient while the other is fed back to the sieves to clear the system from accumulating nitrogen, hence preparing it for the next cycle. Electricity powers the latest POC models, 12v DC and battery packs, therefore, easing the patient’s job of relying on cylinders.
