Due to the shortage of Oxygen in the country, Government of India is decided to import 10,000 oxygen concentrators.

Oxygen Concentrator

It concentrates oxygen from the atmosphere.

Working

  • The atmospheric air has 78 per cent of nitrogen and 21 per cent of oxygen. The Oxygen Concentrator accumulates air, filters through a sieve sending the nitrogen back in to the air and collects oxygen alone.
  • oxygen in the oxygen concentrator is compressed and dispensed through a cannula.
  • The oxygen is available in 90 per cent to 95 per cent purity form.
  • A pressure valve in the concentrators help to regulate the supply of oxygen from 1 to 10 litres per minute.

How is oxygen from Oxygen Concentrator different from Medical Oxygen?

  • The concentrators Oxygen is not as pure as the Liquid Medical Oxygen. However, it is pure enough for mild and moderate COVID-19 patients. It is suitable for patients who require oxygen saturation levels of 85 per cent or above. The Oxygen Concentrators are not advisable for ICU patients.
  • The Concentrators will provide only 5 to 10 litres per minute. The critical patients will need 40 to 50 litres of oxygen per minute.
  • The Concentrators are portable. On the flip side, the Liquid Medical Oxygen needs to be stored and transported in cryogenic tankers.
  • The Concentrators Oxygen only require a power source to draw in ambient air. On the other side, the Liquid Medial Oxygen needs refilling.
  • They are largely one-time investment. They require Rupees 40,000 to Rupees 90,000. The cylinders costs Rupees 8,000 to Rupees 20,000.
  • The concentrators require minimal operating cost that includes electricity and routine maintenance. On the flip side, cylinders involve refilling costs and transportation costs.
