Old people with COPD need to consider many factors when choosing an oxygen concentrator. Here are some suggestions on purchasing an oxygen concentrator:

01 Oxygen flow and oxygen concentration

• Oxygen concentrators of 5 liters or more:

COPD patients usually need long-term home oxygen therapy, and it is recommended to choose a medical oxygen concentrator of 5 liters or more. Because these patients need to inhale oxygen for a long time every day, they may need to inhale oxygen for 15-24 hours continuously. The compressor performance of oxygen concentrators of more than 5 liters is stronger, which can ensure long-term stable oxygen supply and meet the patient's demand for high-flow oxygen during acute attacks.

• Stable oxygen concentration is above 90%:

Stable oxygen concentration is the key to ensuring the treatment effect. You should choose an oxygen concentrator that can ensure an oxygen concentration of more than 90%, so as to provide effective oxygen support for patients.

Firstly recommend RESPIREASY-DEDAKJ star product: KPA-8 MINI OXYGEN COCNENTRATOR

This is a portable oxygen concentrator that can be carried on an airplane and weighs 1.45kg; 3.2lbs. Because it is small and light, it will not bring a large weight burden even in high altitude areas.

This portable oxygen concentrator was also awarded the National Medal of Technology and Innovation in 2024.

Oxygen concentrator and oxygen cylinder

--Which is more suitable for home oxygen therapy?

For home use, it is more appropriate to choose an oxygen concentrator than to buy an oxygen cylinder.

In terms of ease of use, the oxygen concentrator has significant advantages. The oxygen concentrator can continuously and stably produce oxygen without frequent replacement or recharging. It can be continuously supplied by plugging in electricity, while the oxygen cylinder needs to be recharged regularly, and additional operations are required during the recharging and use process, and there are some precautions.

In terms of economic cost, the oxygen concentrator is also more advantageous. Although the initial purchase cost of the oxygen concentrator may be slightly higher, its overall cost will be much lower than that of the oxygen cylinder after long-term use. Because the oxygen concentrator can continuously produce oxygen, while the oxygen cylinder needs to be constantly refilled, and a certain fee is required for each refill. In addition, the maintenance cost of the oxygen concentrator is relatively low, and only regular cleaning and maintenance are required.

From the perspective of safety, the oxygen concentrator is also better than the oxygen cylinder. Oxygen cylinders are flammable and explosive items, and special attention should be paid to safety during storage and use, otherwise serious consequences such as fire or explosion may occur. The oxygen concentrator does not generate any fire source or high temperature during use, so it is safer.

It can be seen that for home use, the oxygen concentrator is not only convenient to use and low in economic cost, but also safer, and can better meet the family's demand for oxygen.
