What is an oxygen concentrator? Difference Between Oxygen Concentrator and Oxygen Cylinder

Oxygen crisis remains an important topic in today’s time, because one of the many diseases, coronavirus has completely changed our way of living and oxygen is required for most of the infected people with this disease.

But it is not possible for everyone to reach the hospital on time and provide them oxygen. Oxygen concentrator is a very useful machine to overcome this deficiency, which you can use in your own home, but for this you need a doctor’s consultation.

For detailed information about Oxygen Concentrator, definitely read this article, we have tried to answer all your questions.

What is an oxygen concentrator?

An oxygen concentrator is a portable machine from which pure oxygen is supplied through a cannula, nasal tube or mask. The oxygen obtained from this is 90 to 95 percent pure. Oxygen concentrators use “Pressure swing adsorption” technology.

The use of oxygen concentrators is more in places where it is difficult to use pressurized oxygen and liquid oxygen. It is used more in doctors’ clinics or homes.

Small portable oxygen concentrators provide up to two liters of oxygen a minute. Whereas large concentrators can provide five to ten liters of oxygen per minute. A healthy person needs 5 liters of oxygen every minute.

Serious patients require 40-50 liters of oxygen per minute, for which oxygen cylinders are needed.

How does an oxygen concentrator work?

78 percent of the air in our atmosphere nitrogen, 21 percent is oxygen and 1 percent is other gases. Air is drawn from the atmosphere by the oxygen concentrator and the nitrogen, carbon and other gases available in this air are removed and pure oxygen is supplied through a nozzle tube or mask.

This whole process goes on simultaneously. It is designed in such a way that it can give oxygen to the patient for a long time. The oxygen concentrator can be attached to multiple tubes if needed, so that it can deliver oxygen to two or more patients at once.

But according to experts, this should not be done in cases of corona, as there is a risk of cross-infection.

Difference Between Oxygen Concentrator and Oxygen Cylinder (Oxygen Concentrator vs Oxygen Cylinder)

oxygen concentrator vs oxygen cylinder

The oxygen concentrator runs on electricity, so the supply of oxygen will continue as long as there is power, whereas after the oxygen in the oxygen cylinder is exhausted, it has to be refilled, for which the oxygen cylinder is taken to the oxygen plant and re-in it. Oxygen has to be filled.

Types of Oxygen Concentrators

There are two types of oxygen concentrators –

1. Continuous Flow Oxygen Concentrator – The continuous flow concentrator continues to supply oxygen in a single flow until it is turned off.

2. Pulse Dose Oxygen Concentrator – The pulse concentrator understands the patient’s breathing pattern and supplies as much oxygen as is needed.

Advantages of Oxygen Concentrator

  • Oxygen concentrators are portable, which are easier to carry anywhere than oxygen cylinders.
  • Oxygen becomes available at low cost.
  • If the power supply is continuous then the oxygen supply continues.
  • It is also a cheap source of oxygen in industrial processes.
  • They require very little maintenance at a low cost.
  • Patients can use the oxygen concentrator at their convenience at home under the supervision of doctors or healthcare workers.
  • Oxygen concentrators are for long term use.
  • No other device is needed with the oxygen concentrator.
  • The oxygen concentrator can be operated with an inverter when there is no power.

Limitation of Oxygen Concentrator

  • The oxygen concentrator supplies 5-10 liters of oxygen per minute, which is not enough for critical patients. Severe patients require more oxygen per minute than this.
  • Oxygen concentrator is beneficial for patients whose oxygen saturation level is between 80 or 85 percent, but it is not effective for patients with severe corona.
  • They can be used continuously for 8 to 24 hours only.
  • It is necessary to keep them closed for 30 minutes for cooling.
  • It cannot be used when the power goes out.

oxygen concentrator price

The price of oxygen concentrator ranges from Rs 30,000 to Rs 3.50 lakh. The rent of oxygen concentrator can range from Rs 3000 per month to Rs 10000 per month. Although the cost of Oxygen Cylinder ranges from Rs 8000 to 20000, but the maintenance cost in the concentrator is very less and it does not have to be refilled like an Oxygen Cylinder.

oxygen concentrator worth
5 LPM Stationary Oxygen Concentrator Rs.30,000 to Rs.65,000
8 LPM Stationary Oxygen Concentrator Rs.66,000 to Rs.95,000
10 LPM Stationary Oxygen Concentrator Rs 70,000 to Rs 1.30 lakh
Pulse Flow Portable Oxygen Concentrator Rs 1.60 lakh to Rs 2.25 lakh
Pulse and Continuous Flow Portable Rs 1.80 lakh to Rs 3.50 lakh

Safety Tips for Using an Oxygen Concentrator

  • Keep oxygen concentrators at least 10 feet away from gas stoves.
  • Do not keep matches, lighters, burning candles and diffusers near it.
  • Don’t smoke around.
  • Do not use anything flammable near it.
  • It is necessary to keep some time off for cooling in between while using continuously.
  • Always keep a fire extinguisher nearby.


You must consult a doctor before using an oxygen concentrator. Using an oxygen concentrator without medical guidance can be extremely harmful.
