When choosing an oxygen concentrator, we first need to establish a unified standard so that it is relatively fair for each brand. We use the national standard of 93% ± 3 as a fixed reference value for the oxygen concentration produced by the concentrator.
On the premise of meeting this standard, the maximum oxygen output of the concentrator is 1L, 3L, 5L and as reference standards to define the target audience and performance of the concentrator:
1L oxygen concentrator is suitable for students and pregnant women who generally need oxygen therapy, provided that the oxygen concentration meets the standard. It provides about 30 minutes of oxygen therapy to relieve temporary fatigue and provide more energy.
3L oxygen concentrator can meet the standards of medical oxygen and is suitable for elderly people at home to receive health oxygen therapy or for patients with chronic diseases such as hypertension, hyperglycemia, hyperlipidemia, coronary heart disease, obesity, etc. The main purpose is to increase blood oxygen saturation. If there is more oxygen in the blood and it meets the standard, it can prevent the occurrence of other diseases.
5L oxygen concentrator is suitable for patients with heart and lung functional diseases. It can not only meet serious diseases such as emphysema, pulmonary heart disease, and moderate to high chronic obstructive pulmonary disease, but also meet the needs of long-term oxygen supply and effectively alleviate sudden acute wheezing patients.
