The choice of how many liters of oxygen generator mainly depends on the user population and performance requirements. Under the premise that the oxygen concentration stipulated by the state is 93%±3, it can be divided into 1L, 3L, 5L, 8L, 9L, 10L, etc. according to the maximum oxygen output of the oxygen generator. Various liters can be the reference standards to define the adaptability and performance of the oxygen generator:

■ 1L oxygen generator

The 1L oxygen generator is suitable for pregnant women who need general oxygen inhalation and mental workers (such as students and white-collar workers in companies) who work and study for a long time. It is mainly used for health care. Generally, oxygen therapy can be carried out for about 30 minutes to relieve temporary Fatigue, more energy.

■ 3L oxygen generator

It is suitable for oxygen therapy at home for elderly patients or patients with some chronic diseases (such as cardiovascular and cerebrovascular hypoxic diseases, hypertension, hyperglycemia, obesity, etc.). The main purpose is to improve blood oxygen saturation and prevent the occurrence of some other diseases.

■ 5L oxygen generator

Suitable for patients with cardiopulmonary functional diseases (such as chronic obstructive pulmonary disease, pulmonary heart disease).

■ 8L oxygen generator

The 8L oxygen generator is mainly used for special patients with high oxygen flow and long-term oxygen inhalation. Such patients generally cannot be freed from oxygen for a long time. Therefore, with this oxygen generator, it is avoided to spend time and effort to fill the oxygen cylinder with oxygen repeatedly every few days.

After inhaling oxygen through the oxygen generator, the effective oxygen concentration in the patient's lungs is jointly determined by the oxygen output flow of the oxygen generator and the corresponding oxygen output concentration. For example, excluding the influence of patient factors such as respiratory frequency and tidal volume, when oxygen is inhaled by nasal cannula, the effective oxygen concentration (%) reaching the patient's lungs = 21+4 × oxygen output flow of the oxygen generator × oxygen generator Oxygen concentration.

If it is used for treatment, it is recommended to buy an oxygen generator with an oxygen output of not less than 3L. For patients who need long-term oxygen therapy, it is recommended to use an oxygen generator of not less than 5L. Giving a relatively high oxygen flow, more importantly, can ensure a long-term oxygen supply, and the oxygen concentration can be stabilized at more than 90%, so as to achieve a good therapeutic purpose.

JoRadiant medical grade oxygen generators are available in 1L, 3L, 5L, 8L, 10L and other models to meet the oxygen inhalation needs of different groups of people. We hope to help you. If you are not sure how to choose how many liters of oxygen concentrator, you can enquire us anytime.
