Patients with mild to moderate COVID-19 cases who require external oxygen support can use an oxygen concentrator. Medical experts suggest that the concentrator can be used if the oxygen saturation level is between 90-94, or those with oxygen levels even as low as 85, in case of scarcity.

How does a concentrator work? It sucks in atmospheric air, filter nitrogen and other gases, compresses remaining oxygen and dispenses it through the cannula.

For oxygen concentrators available for home-based care, there are some parameters that need to be checked to ensure good oxygen quality output, advised Central Drugs Standard Control Organisation (CDSCO). Take a look:

*Digital or analogue meter that displays cumulative hours of device operation

*Oxygen concentrators of less than five litres per minute capacity may not be sold under the misleading label ‘For Home-Based COVID Care’.
