Oxygen Concentrator 

If someone has some health issues and it is related to causes your oxygen level drops instantly too low. An oxygen concentrator is a device that provides you with extra oxygen your doctor recommended if you are suffering from lower oxygen levels. 

This device helps people is someone suffering from trouble breathing due to these conditions; 

  • Covid-19 patient 
  • Asthma patient 
  • Lungs cancer patient 
  • Someone suffering from FLU

Make sure you use the oxygen concentrator device according to the doctor’s prescription and guidance. Your doctor guides you on how much oxygen you should take and how long you should use this device.

Types of Oxygen Concentrator Machine

There are two types of oxygen concentrator machines available on the market pulse dose & Continuous flow oxygen concentrator and intermittent flow oxygen concentrator these devices have different benefits and constraints and are best suited for specific patients. 

Pulse Dose & Continuous flow oxygen concentrator

This portable oxygen device has two different types of setting the pulse dose and continuous flow concentrator.

The pulse dose concentrator mode is used usually during the daytime it delivers air through the cannula when you inhale oxygen concentrator pulse dose technology is more close-packed in design and offers a longer battery life. 

The Continuous flow of the oxygen concentrator mode delivers a constant airflow through the tubes. This type of component is for the people who need oxygen while they are sleeping. This mode is best for heavier home units. 

Benefits of oxygen concentrator differences portable & home units

Both of these oxygen concentrators or portable and home units have several types of advantages for people who need oxygen therapy. 

The oxygen concentrator is less dangerous in comparison to traditional oxygen cylinders. Which is a leakage problem or increases the chances of firing. That old-fashioned liquid oxygen cylinders have caused the kindling. 

On the other hand, oxygen concentrators are not dangerous. Portable and home oxygen concentrators, manufactured their own oxygen without the further ongoing cost of refilling tanks of oxygen. Has become more popular than old-fashioned oxygen tanks.

Things to consider before buying oxygen concentrator

one of the most important factors before buying oxygen concentrator machine is check the flow rate capabilities flow rate indicates the rate of which oxygen is able to travel from the machine to the patient.

Check the flow rate 

An ideal process is before buying the oxygen concentrator to advise the ideal flow rate it is recommended that you have to discuss any potential oxygen concentrator purchases with your doctor first. 

The Power consumption 

The power consumption of your device should be in the range of. It is advisable to purchase the concentrator that boosts the lowest power consumption and your oxygen requirements as per your doctor prescription.


It is good to consider and prescribed by the doctor before buying and spending on any type of oxygen concentrator the quality should be your first concern your machine quality as an on the top and most important thing is before buying any oxygen concentrator check the reviews and features of your product.

FAQs: Oxygen Concentrator

  1. What is the price of oxygen concentrator?

The minimum price of oxygen concentration in India is 30,000 to 70,000 apart from that it utterly depends on which type of model you want the prices according to the models and product quality.

2. How can I decide on the best oxygen concentrator? Before buying it.

Before buying the oxygen concentrator some things you should keep in your mind are flow rate, noise, portability, oxygen concentrator.

3. How many hours we should use the oxygen concentrator?

Generally, the life of an oxygen concentrator hours of life 1,500 to 2,000.

4. What is the maximum concentration of oxygen that can be achieved with the concentrator?

up to 94%

5. How many babies can be treated at a time with the oxygen concentrator?

up to 4 babies using a spillter.

6. What is the running cost of equipment?

The initial cost of the equipment is 45,000 to 50,000 which may be considered expensive in comparison to cylinders the yearly running cost of 12,000 to 15,000 is substantially, less than the Rs 2.5 to 3 lakh for providing cylinders and the Rs 1.2 to 1.3 lakh for liquid oxygen. Thus on cost alone, the oxygen concentrator is the preferred means of providing oxygen treatment in developing countries with limited resources.

7. What is the life of the Zeolite sieve filters?

The life of the zeolite crystals can be expected to be at least 20,000 hours which in
most situations would give about 10 years use.

8. What kind of maintenance is required for the oxygen concentrator?

The device is as simple to manage as it looks. All that is required is that the coarse
filter has to be washed each day and replace the other filters as per instructions of
the company, which is usually at 6 months or 1500 hours of use. The filters may
also need to be changed according to local conditions (dust, humidity) and the
amount of use of the concentrator. Skilled mechanical maintenance is needed only
yearly. There is a fourth filter, the bacterial filter, located before the oxygen outlet of
the concentrator. Typically this must be changed every year, or more frequently,
depending on the amount of use of the concentrator. The concentrator may work 24
hours a day, every day, as long as daily maintenance procedures are carried out.
Every concentrator has an hour meter. The working hours should be written down
in the service report.

9. What are the Precautions during usage of the oxygen concentrator?

The precautions to be observed are:

• The concentrator should be placed as far away from the window as possible to avoid dust and moisture.

•The concentrator should not be used to deliver oxygen through head box or face mask but use cannula.

• It should be kept far away from open flames.

•Oxygen cylinders are recommended as a backup oxygen supply system in case of power failure as the oxygen reservoir in the machine lasts for only 2-3 minutes.

•When a flow-splitter is being used, the total flow should not exceed more than 4 liters per minute or the concentration of oxygen will decrease. This happens because the canisters have a defined volume and can only separate a known volume of nitrogen at a given time. Therefore, concentrators must not be used at flows higher than those stated by the manufacturer.

10. What are the other methods of providing oxygen therapy?

The other methods of providing long term domiciliary oxygen are cylinders delivered
to the patient’s home (the most widely used method) and liquid oxygen in a domestic
tank replenished twice weekly in some countries. The capacity of the oxygen
cylinder can range from 40- 3445 liters capacity and cost between Rs. 2,625-
12,215. The cylinder can provide oxygen at 1 LPM for 11.3 hrs (e.g.680 litres
capacity cylinder) or 4 LPM for 2.8 hrs. Thus the overall running costs turn out to be
much higher than the oxygen concentrator. The use of a liquid oxygen system has
been investigated in the United States. The apparatus consists of a portable “walker”
and a reservoir which contains a supply for three to four days.

Regular deliveries are
required as for cylinders and this contributes appreciably to the cost.
