• A portable oxygen concentrator (POC) is a device used to provide oxygen therapy to people that require greater oxygen concentrations than the levels of ambient air. • It works based on the principle of Pressure Swing Absorption (PSA), which involves separation of gas species from a mixture of gases under suitable pressure. • The internal compressor forces this air through a system of chemical filters known as a molecular sieve. • This filter is made up of silicate granules called zeolite which attract (via adsorption) nitrogen molecules onto their surfaces more strongly than they attract oxygen molecules – this takes the nitrogen out of the air and concentrates the oxygen. • The atmosphere contains around 21% oxygen and 78% nitrogen; the 1% remainder is a mixture of other gases which pass through this process. • A POC system is functionally a nitrogen scrubber capable of consistently producing medical-grade oxygen of up to 90%.
