What is oxygen concentrator?

An oxygen concentrator is a device which concentrates the oxygen from a gas supply (typically ambient air) to supply an oxygen-enriched gas stream.

How does an oxygen concentrator machine work?

It works by taking in air from its surroundings , compressing air, while the cooling mechanism keeps the concentrator from overheating , removing nitrogen from the air via filter and sieve beds , adjusting delivery settings with an electronic interface ,delivering the purified oxygen via a nasal cannula or mask.

How many types of oxygen concentrators are there?

There are two types of oxygen concentrators :

  • a.Stationary oxygen concentrator
  • b.Portable oxygen concentrator

What is the difference between stationary and portable oxygen concentrator?

The two main differences between stationary and portable concentrators are their size and flow rates.

Stationary oxygen concentrators are generally larger and heavier than the portable oxygen concentrators, but they can also offer higher flow rates and are often recommended for patients who need more oxygen than portable concentrators can provide. Stationary oxygen concentrators can deliver 3 to 10 liters of oxygen per minute; portable models deliver from 1 to 5 liters per minute. They are sometimes called home oxygen concentrators.


Portable oxygen concentrators provide greater flexibility for respiratory patients who do not require high doses of oxygen. They can run on a variety of power sources and can charge from a wall outlet, a car adapter, or a battery pack. Portable oxygen concentrators are made small enough to carry in under one arm, in a backpack, or attach to a cart or walker so the patient can move about freely at home or while traveling. Portable concentrators weigh between 5 and 20 pounds and many come with carrying cases or carts for additional convenience.

What is stationary oxygen concentrator?

Stationary oxygen concentrators are machines that provide oxygen, continuously, at higher levels of concentration than what can be found in the surrounding air. For Example : Everflo Oxygen Concentrator.

What is a portable oxygen concentrator?

Portable oxygen concentrator (POC) is a portable device used to provide oxygen therapy to people requiring greater oxygen concentrations than the levels of ambient air. It is similar to a home or stationary oxygen concentrator, but is smaller in size and more mobile.

What is pulse flow?

This mode enables / prompts the Oxygen Concentrator to produce Oxygen only when the patient is actually inhaling and not otherwise; hence, reducing load on the machine.

When a patient inhales, it causes negative air pressure which activates the Oxygen Concentrator to provide Oxygen at that very moment as and when required.

What is continuous flow?

Continuous flow means the Oxygen produced by the machine is being delivered continuously to the patient, whether the patient is inhaling or exhaling.

What is Pulse Flow and how is it different from Continuous Flow ?

Pulse and continuous flow (or pulse dose and continuous flow dose) refer to how the oxygen is delivered to the patient. A pulse flow machine delivers oxygen only when the patient inhales and is triggered by inhaling. A continuous flow machine delivers a continuous flow of oxygen. Most continuous flow machines will deliver BOTH pulse and continuous flow.

Will my body get dependent on oxygen if i use it continuosly?

No, Oxygen is not addictive at all. Supplemental Oxygen is prescribed because the lungs have become weak due to condition like COPD and the 21% Oxygen of air is now not sufficient for lungs which results in low level of O2 in blood.

In order to make lungs feel like as if they are exactly in a normal healthy environment, they need some extra Oxygen so that the Oxygen exchange with blood is exactly same as it would have been with normal healthy lungs.

Do i need to keep an oxygen cylinder at home if i m using an oxygen concentrator?

It is recommended to keep an Oxygen cylinder as a backup source. After all, concentrator is a machine and any machine can fail anytime.

When do i need to use a humidifier bottle?

The purpose of humidification is to provide moisture which makes Oxygen therapy comfortable; if not used, can cause dryness in airways of nose and throat. Usually, use of humidifier is recommended in continuous flow of more than 3 LPM.

Do I have to place my order online?

You can place your order online or over the phone – whatever method you are more comfortable with.

What is the difference between the various oxygen concentrator models?

There are a few differences between oxygen concentrators. Some of the main differences are litre flow range, weight, noise produced, size, power source, portability, and price.

How do I operate an oxygen concentrator?

Stationary oxygen concentrators operate basically the same way. They have a power switch, they need a power source to operate, they have a flow meter to adjust the flow, and produce roughly 95% oxygen. Locate your concentrator where it has about 1 foot clearance from all sides for ventilation. Plug the machine in to the wall. Do not use a power strip or extension cord. Turn the power switch to the on position. The machine will beep briefly – this is normal. Adjust the litre flow to your prescribed amount by turning the litre dial. The ball should split the line associated with the desired flow.

What is an oxygen humidifier?

An oxygen humidifier is a plastic bottle that attached between the oxygen concentrator and supply tube going to the end user. It adds moisture to the oxygen breathed by the end user.

How often do I need to clean or replace my filters?

If your concentrator has a foam cabinet filter, it should be cleaned weekly. Simply remove the filter, rinse under the sink, & pat it trywith a paper towel. Do not put it back until dry. The internal filters (compressor intake & bacteria filter) should be replaced every year.

Do you sell replacement filters for CPAP's and concentrators?

Yes. If you don't see it online, give a call.

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

Up to 94%

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 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.

How do i care for my humidifier?

To care for your humidifier simply empty and clean the water tank each morning. Only distilled water should be used in the humidifier to avoid mineral deposit build up.

How Often Should I Change my Oxygen Cannula and tubing?

If you are only using your cannula and tubing a few hours a day, it is recommended that you change your tubing and cannula, every 3-6 months. If you use your concentrator more than a few hours a day, it is recommended to change your cannula on a monthly basis and your tubing, at least, every 2-6 months.

How often should i wash the tubing?

You can clean it about once a week using vinegar and water solution, as well as a mild detergent such as Dawn dish soap. It's recommended that you wash the nasal cannula with 1 part water and 1 part vinegar to safely kill the germs, and then wash it in hot water with a small amount of Dawn. Rinse it thoroughly and hang it to dry. Make sure it is completely dry before using it again.

Which things should i keep in mind while using humidifier bottle?

a. Only fill to the maximum level marked on the bottle. Filling above this level may cause water to be pushed into the concentrator, causing damage to the unit.

b. It is recommended to use RO water wherever possible as this prevents potential mineral build up occurring if using tap water.

c. Always check the water level through the day and refill if the level falls below the minimum level marked on the bottle.

d. Empty the bottle daily. Wash the lid and bottle using a mild detergent, rinse thoroughly and either dry with a clean cloth, or air dry.

e. Refill with RO water.
