How to choose a home use oxygen concentrator?

dedakj oxygen  concentrator parameters

Different specifications of home oxygen concentrators for different needs

1L oxygen concentrators are often used for health care, and pregnant women, students, office workers and other people who use their brains for a long time can achieve health care effects such as enhancing immunity;

3L oxygen concentrators are often used for elderly health care, hypertension, cardiovascular and cerebrovascular hypoxia, hyperglycemia, obesity, etc.;

5L oxygen concentrators are often used for cardiopulmonary functional diseases (chronic obstructive pulmonary disease, cor pulmonale);

10L oxygen concentrators are often used for special patients with high oxygen flow and long-term oxygen inhalation.

Working principle of oxygen concentrator

Home oxygen concentrators generally use the molecular sieve oxygen production principle. The air is compressed by a compressor, and then the molecular sieve is used to adsorb nitrogen in the air under pressure. The remaining unabsorbed oxygen is collected and purified to become high-purity oxygen. When the molecular sieve is decompressed, the adsorbed nitrogen is released to complete a cycle. This oxygen production method is highly efficient, and the oxygen production concentration can reach more than 90%, which is suitable for home use.

If you buy a home oxygen concentrator for the elderly at home, you need to choose a machine that is easy to operate. The fewer buttons and the simpler the operation, the more convenient it is for the elderly to use.

Noise level

The noise level of the oxygen concentrator is an important consideration because it directly affects the user experience. According to relevant standards, the noise level of the oxygen concentrator should be controlled within a certain range to ensure that it does not cause excessive interference to the user. The noise level of the oxygen concentrator should not exceed 60 decibels to ensure that it does not cause discomfort to the user under normal use conditions. The noise in the room should not exceed 55 decibels during the day and 45 decibels at night.

Portability, convenience and mobility

The weight range of home oxygen concentrators is roughly between 5-23 kilograms.

Specifically, 1L oxygen concentrators are mainly used for health care, 3L oxygen concentrators are suitable for elderly health care, hypertension, cardiovascular and cerebrovascular hypoxia diseases, etc., 5L oxygen concentrators are suitable for cardiopulmonary functional diseases, and 10L oxygen concentrators are mainly used for special patients with high oxygen flow and long-term oxygen inhalation.

Oxygen concentrators of different specifications have different weights.

For example, a 3L oxygen concentrator weighs about 11-15 kg, and a 5L oxygen concentrator weighs about 15-23 kg. In addition, the weight of a medical oxygen concentrator is usually between 11-30 kg, while a healthcare oxygen concentrator weighs 5-10 kg. The portability of a home oxygen concentrator is also a consideration. A general oxygen cylinder weighs 50-60 kg, which is inconvenient to move, while a home oxygen concentrator weighs about 20 kg, and basically has universal wheels, which makes it relatively easy to move. Portable oxygen concentrators have special storage bags and straps that can be carried with you.
