Choose your portable oxygen concentrator 

Why do I choose an oxygen concentrator?

Some people have such limited lung function that they cannot get enough oxygen by just breathing. A lung specialist may then prescribe supplemental oxygen. A person in need of supplemental oxygen may choose from several oxygen sources.

Liquid oxygen system, a large 35ltr tank from which small supplies can be tapped for outdoor use
(Portable) cylinder, filled with 2 litres of pressurised oxygen, weighs less than 5 kg
Concentrator, an electric generator that sucks in air and filters it into concentrated oxygen

Like everything in life, there are advantages and disadvantages to each method. When considering convenience and safety, we at Conec Care find a concentrator to be the most convenient oxygen source. The disadvantages of a concentrator (makes noise, requires electricity and ventilation) are generally easy to solve. But the advantages easily outweigh these disadvantages.

How does a portable oxygen concentrator work?

An oxygen concentrator is a source of oxygen that creates medicinal oxygen from the ambient air with the help of a motor and a filtering/screening system and offers it to the user in a concentrated form through a hose. A portable oxygen concentrator is a similar system, but smaller and lighter and with a battery as power source. This allows you to be independent from mains power when out and about. Ideal for holidays, walks, museum visits or an afternoon shopping. A portable oxygen concentrator gives you freedom and that is priceless.

What is the ideal portable oxygen concentrator?

The ideal oxygen device is a concentrator that:

• is small and light
• Can go for long periods without power
• Can produce a lot of oxygen in ‘continuous flow’

Unfortunately, there is no device that meets all these characteristics. In the end, you have to settle for a compromise.

Size and weight affect the amount of oxygen that can be produced and the time the device can operate without recharging. The smaller the battery, the shorter its lifespan. The smaller the device, the slower it can filter and thus the maximum production is limited.

Continuous flow oxygenation requires so much energy that it will severely limit autonomy. Therefore, all portable devices are equipped with a ‘pulse dose’ system. Only when there is a demand for oxygen in the nosepiece, the oxygen concentrator produces a puff of oxygen. This is very fast and very precise, so it works well for almost everyone, but it is not suitable for delivering oxygen when using a mask or, for example, in combination with a CPAP device. There are solutions for that, but more about that in the article about autopulse. Even if you are convinced that you need continuous flow, we can examine whether autopulse offers a solution for you.

Are there no portable concentrators with continuous flow at all?

Yes, there are, but with important limitations. The maximum oxygen production is limited to 2 sometimes 3 litres per minute, the maximum time the device can be used without recharging is very limited per individual battery (think 1-2 hours) and the weight of the available devices is between 4.5 and 8.3 kg. This class can be seen more as a portable oxygen concentrator. You can move it around independent of a power point, but it is not comfortable to use.

So, what choice do I have?

Conec Care supplies the products of Inogen because we believe in the quality and durability of this company. We think alternative brands like Philips, GCE are fine options, but the Inogen concentrators are better. Inogen sets the standard in the market.

Within the portable range of Inogen there are 3 choices

What type of Inogen One oxygen concentrator should I choose?

Check the advice below to see where you fit in best.

Flexibility

If you are looking for the most flexible solution and find a weight of between 2 and 3 kg acceptable, go for the G5, or if you want to save some money go for the G3. The G5 is more modern than the G3, has a longer battery life and can produce a little more oxygen, but the G3 is a little cheaper in most cases.

If you want to fly and need extra oxygen while flying, choose the Inogen One G3 or G5. The weight is a bit higher than the G4, but at 2-3kg it is acceptable. And the battery life is so generous that you can do with less batteries.

If your oxygen requirements are unstable and possibly growing, choose the G5 or G3. If you go for the G4 and your demand exceeds 3 litres per minute, this unit is useless and you should look for an alternative with a higher oxygen production.

Volume and weight

If small size and low weight is essential, choose the Inogen One G4 provided your oxygen needs are stable at 1 or 2 litres, with a maximum spout up to 3 litres per minute.

If you want to fly but weight is essential then choose the Inogen One G4 provided this device fits your oxygen needs. However, you will need to carry more batteries. This is expensive and also contributes to the total weight, but the device you carry yourself is lighter than an alternative. The remaining weight can be carried in a bag or suitcase.

oxygen consumption

If you mainly stay for a shorter time around the house or hotel, you mainly travel by car and your oxygen requirement is stable at 1 or 2 litres, with a maximum of 3 litres per minute, then you can choose any alternative. But the G4 will do and it is the most comfortable because it is so small and light.

If your oxygen needs are above 3 litres per minute, then choose the Inogen One G5 or the G3.

Location

If you are often in remote areas, choose the G3. It is easier to get parts for it, has been on the market for so long that you have a greater chance of getting them quickly. In addition, we or other Inogen dealers can provide remote support more easily.
