What is an oxygen concentrator machine?
An oxygen concentrator is defined as a machine or a medical device that takes in atmospheric air, concentrates oxygen from that ambient air, and then delivers that oxygen into a person via a nasal cannula.
The atmospheric air contains 78% nitrogen, 21% oxygen, and 1% other gases. At the same time, the air (oxygen-enriched product gas stream) produced by the oxygen concentrator has up to 95% pure oxygen in it. Therefore, this air is suitable for patients suffering from lung disease, especially during this pandemic time (covid-19).

An essential feature in POC that only Philips Respironics Simply Go holds is the three operating modes to supply oxygen. 1. Continuous flow 2. pulse mode 3. Sleep mode.
Pulse mode detects the breath intake and then delivers a pulse dosage of oxygen at the start of the breath.
Thus, pulse mode is an efficient way to supply oxygen-enriched gas to the patient because it avoids the unnecessary wastage of the oxygen, wastage as happens in continuous flow.
Note Pulse mode is helpful for patients demanding oxygen up to 2 LPM as pulse technology can also offer portable oxygen to such patients while traveling or walking, and the patient can effortlessly consume it without wastage; this saves not only oxygen but also increases battery life. If the oxygen requirement is higher than 2 LPM, then the continuous flow of oxygen is recommended. Also, pulse mode is not recommended during the sleeping time because while sleeping, patients may lead to shallow breathing, and pulse technology can't always detect shallow breathing.
Suppose in pulse mode; the oxygen concentrator cannot detect the breath for a specific period.
In that case, the concentrator will automatically deliver the pulse dosage of oxygen according to the mode setting at a fixed rate of 12 breaths per minute. But in case if unable to detect the breath for 2 minutes, the concentrator indicates an alarm and shuts down after 30 minutes.
Sleep operating mode is much similar to pulse operating mode, but in sleep mode, breath detection is at a more sensitive level because while sleeping, a patient may lead to shallow breathing, which requires an extraordinary detection level.
Suppose the concentrator is not able to detect the breath for a specific period during sleep operating mode. In that case, the concentrator will automatically supply the continuous oxygen to the patient according to the most recently used setting of Continuous Flow Mode.

Why is an oxygen concentrator necessary for patients isolated at home?
During covid-19, when a patient is isolated at home, there is a maximum chance that patients can recover quickly while maintaining oxygen levels above 95%.
But if oxygen level becomes low for a particular time or the patient is continuously suffering from lung disease and continuously maintains oxygen level, i.e 85%<oxygen saturation<95%, then there is a need for an oxygen concentrator machine capable of providing the oxygen-enriched product gas stream containing 90-95% oxygen.
It is the best option to take care of your family member without admitting him/her to the hospital.
But suppose the oxygen level in patients is deficient. In that case, i.e., oxygen saturation<85%, then it is recommended to take medical services instead of consuming oxygen from an oxygen concentrator because the air (gas stream) produced by the oxygen concentrator contains 90-96% oxygen in it but for the patients suffering from oxygen level< 85% demands an oxygen-enriched product gas stream containing 99% oxygen in it. In that situation, mechanical ventilation is the best option.
Oxygen Concentrator Buying Guide: Tips to purchase the right one
An oxygen concentrator is essential to purchasing if a patient is suffering from low blood oxygen levels.
Insufficient oxygen level in the blood stops the proper functioning of the heart and brain that causes serious injury to the body. Therefore to overwhelm this problem, oxygen concentrators are manufactured.
Several companies are selling their oxygen concentrators in the market, and each of them possesses different features. So it becomes very difficult to purchase the right one among them.
To overcome such a situation, we have written a detailed buying guide and mentioned all the necessary factors that you must remember while purchasing an oxygen concentrator.
Important factors to consider while purchasing an oxygen concentrator
Oxygen Saturation level
Before you decide on purchasing the oxygen concentrator, first check the oxygen saturation level of your body.
The oxygen saturation level will indicate if there is any requirement of purchasing the oxygen concentrator. Also, please consult the doctor and take relevant advice from them. Another option to check your oxygen level is through the pulse oximeter.
As shown in the pulse oximeter, if your blood oxygen level is more than 95%, you are safe and do not require any oxygen concentrator. But if your oxygen saturation level scales from 87%-95%, it is recommended to prefer an oxygen concentrator at home. If it is less than 87%, you must take medical treatment and admit yourself to the hospital for proper treatment.
After oxygen saturation level, the capacity of an oxygen concentrator is a must look factor before purchasing it.
Capacity means how much maximum oxygen the oxygen concentrator can deliver to the patient in litres per minute (LPM).
Different oxygen concentrators of maximum capacities such as 5 LPM, 8 LPM, 10 LPM are available. As per the oxygen saturation level, the doctor will suggest the suitable amount of oxygen that the patient needs to consume in his whole day.
In most cases, the patient is not critically ill and requires the amount of oxygen that can be delivered comfortably by the oxygen concentrators having a maximum capacity of 5 LPM. After the doctor’s appropriate advice, you can surely pursue it.
Flow rate can be defined as the rate at which oxygen is delivered to a patient from the machine. It is another vital factor to consider after you have decided the capacity of an oxygen concentrator.
Oxygen concentrators hold a flow meter knob that adjusts the oxygen flow as per patient requirements.
Oxygen flow can be adjusted from minimum oxygen capacity to maximum oxygen capacity of the oxygen concentrator (in LPM), i.e. if a concentrator can deliver the maximum of 5 LPM oxygen to the patient, that means the flow knob can adjust it from 0 to 5 LPM.
It is always advised to purchase an oxygen concentrator having a capacity more than your requirement.
Stationary or portable
Oxygen concentrators are available of both types, stationary and portable. Portable oxygen concentrators are very costly as compared to stationary oxygen concentrators.
The portable one is suitable for patients demanding oxygen upto 4 LPM, and above 4 LPM oxygen requirement, it is suggested to purchase stationary oxygen concentrators.
Portable concentrators are costly, lightweight and easy to carry, while stationary concentrators are the opposite of these. Portable concentrators are not fit for the patients demanding oxygen continuously for 24 hours.
Yes, portable oxygen concentrators are best in features as they have a battery system, both pulse and continuous flow, FAA certified for travel. But in the end, you can make decisions based upon your budget and oxygen requirement.
The percentage of oxygen in the filtered air provided by the oxygen concentrator in the form of a gas stream to the patient is referred to as oxygen concentration.
Oxygen concentrators are designed in a way that they can provide the air containing 90-97% oxygen. Oxygen concentration in the purified air can fluctuate depending on the filtration system of the concentrator.
Also, concentration of oxygen is different at different oxygen flow rates. Here the molecular sieve bed present in the machine performs a significant role in removing nitrogen molecules from the ambient air.
It is always better to purchase higher-powered stationary oxygen concentrators if a person demands continuous oxygen with more than 90% oxygen concentration.
Portable oxygen concentrators are better if patients’ oxygen requirement is less than 2 LPM with a maximum 90% concentration.
Power consumption is the factor that most people ignore at the beginning that leads to massive increment in electricity bills due to oxygen concentrators.
Oxygen concentrators available in the Indian market consume power from 300-800W.
When it comes to power consumption, portable concentrators are the best option because they hold a rechargeable battery which allows them to operate in the absence of electricity. At the same time, a stationary concentrator works only when power is supplied to them.
Oxygen capacity, flow rate, and oxygen concentration are the priority factors you must look at while purchasing. After that, you can proceed with the device that consumes less power and satisfies all the above factors.
Oxygen purity indicator
Oxygen purity indicator (OPI) indicates whether oxygen supplied to the patients contains a suitable amount of oxygen concentration or not.
OPI symbolizes in the form of LED light or alarm mode depending on the oxygen concentrator you are purchasing. Also, along with OPI, some concentrators show oxygen purity percentages on display to ensure that delivered oxygen is appropriate.
All the products mentioned above hold such valuable features that you can acquire them confidentially.
Usually, companies provide the most trustworthy service after-sale to satisfy customers. Still, you must research well before purchasing an oxygen concentrator of a particular brand.
If the service center is not easily available in your location, don’t forget to contact their customer care numbers before you purchase. Otherwise, you may have to face immense problems.
Like all other appliances, oxygen concentrators also possess a warranty period.
The standard warranty of oxygen concentrators is 2-3 years. But different companies have different warranty policies, so you must check their warranty period to get the maximum benefit from the company.
Generally, oxygen concentrators are a long-lasting product that constantly works for years, but you can claim a warranty and exchange it in case of any technical issue.
Which one is better: Nasal Cannula or Oxygen mask?
Both of the oxygen administration devices perform well with oxygen concentrators, but which is necessary to use depends upon the patient’s oxygen requirement.
The nasal cannula is a comfortable and great option for the patient demanding oxygen upto 6 LPM. If the oxygen requirement is more than 6 LPM, then an oxygen mask is a better option. The oxygen mask is usually available with a high flow oxygen concentrator and cannot be used with a concentrator’s pulse flow mode.
Both nasal cannula and oxygen masks are available in the market with adjustable lengths to adjust the size according to convenience.
How Does an Oxygen Concentrator Work?
The oxygen concentrator starts functioning when it is connected to the electrical socket.
Portable oxygen concentrators include a battery system due to which they can operate in the absence of electricity, i.e. while you are travelling in flight or attending a meeting. The included battery is rechargeable that can be charged when the concentrator is connected to electricity.
The working process of the oxygen concentrator is straightforward. An oxygen concentrator takes in the atmospheric air from the external environment, compresses it, removes nitrogen from that ambient air, and then delivers the oxygen-enriched gas stream to the patient.
Working process: Converting air into an oxygen-enriched gas stream
The oxygen concentrator includes various assistants responsible for performing numerous functions inside the machine to deliver 90-95% pure oxygen. Compressor and molecular sieve beds are in a leading role in extracting oxygen from the ambient air.
The concentrator takes in the atmospheric air passed through the compressor; the compressor compresses the air and transfers this compressed air to the surge tank via a heat exchanger. Here heat exchangers lessen the temperature of compressed air to enhance the adsorption process.
The compressed air is moved to the molecular sieve beds through the surge tank, where the adsorption process occurs. In the molecular sieve bed there present a material known as zeolite responsible for removing nitrogen from the air.
In oxygen concentrators, two sieve beds are positioned. When the air is passed through the compressor, it is forced into the first sieve bed. Here the pressure of air in the first cylinder increases 2.5 times than the normal atmospheric pressure.
The nitrogen is removed from the compressed air in the first sieve bed, and pure oxygen is transferred to the oxygen tank. It completes the first half cycle of an oxygen concentrator. Here at this time, the first sieve bed gets filled with nitrogen molecules.
The four-way solenoid wall changed the gas flow in a second-half cycle and transferred the compressed air into the second molecular sieve bed. Here the same process takes place as of the first sieve bed.
When compressed air is passed through the second sieve bed, the pressure inside the first sieve bed becomes normal, making zeolite release nitrogen molecules in the external environment. As it releases nitrogen, the first sieve bed is again ready for the adsorption process. Here one cycle is completed, and now both the sieve beds are prepared for the second cycle.
After the half-cycle, oxygen is moved to the oxygen product tank. With the help of a flow metre adjusting valve (adjust the oxygen flow as per patient requirement), pure oxygen is passed through the humidifier bottle, where dry oxygen gets moisturized. Finally, a patient can inhale this oxygen-enriched gas stream via a nasal cannula.
Note: Here in the working process, the air flows continuously inside the oxygen concentrator.
