Oxygen Concentrator Shopping Guide

First, let's understand what oxygen flow and oxygen concentration are

Oxygen flow rate

Unit: L/min

Refers to the air output per minute of the oxygen concentrator, for example, 3L/min means the oxygen concentrator can output 3L per minute.(PS: oxygen flow rate is basically adjustable)

Oxygen concentration

Unit: percentage

Refers to the percentage of oxygen in the output of the oxygen generator. For example, 90% oxygen concentration means the percentage of oxygen concentration in the produced gas is 90%. (PS: Only oxygen concentration of 90% or more is effective for human body)

Second, let's understand the different models

Patients can follow the medical advice to buy according to the condition

Oxygen concentrators are available in 1L, 2L, 3L, 5L, 8L, 10L, which indicates the maximum oxygen flow per minute that the oxygen machine can provide under the premise of oxygen concentration guarantee. The oxygen flow rates for different populations are different.

1L and 2L are mainly used for health care oxygen intake for people with mild hypoxia.
3L and 5L are the most common types and also the most numerous. 3L is between health care and slight treatment function, while oxygen concentrators above 5L belong to the treatment type, which has medical assistance for patients with respiratory system diseases and lung diseases.
8L and 10L are suitable for special patients who need high oxygen flow and long-term oxygen intake, such as those suffering from severe chronic obstructive pulmonary disease, pulmonary heart disease, stroke and other diseases, as well as post-operative rehabilitation and hospital oxygen sources.

Finally, let's understand oxygen therapy and oxygen health care

Oxygen therapy and oxygen health care both use oxygen supplementation to improve the body's hypoxic condition and promote metabolism, in order to treat related diseases and enhance body functions.

Oxygen therapy is used to correct pathological hypoxia and treat diseases. Patients with respiratory diseases, patients with cardiovascular diseases, and elderly people over 65 years old are the main groups of oxygen therapy. (PS: these people need to use medical oxygen machines)

Oxygen is used to correct physiological hypoxia, to enhance physical fitness, prevent diseases and improve work and study efficiency, etc. Oxygen is called oxygen health care. Brain workers who work hard, students preparing for exams who are under stress, and pregnant women who are expecting to give birth all need some supplemental oxygen. (PS: generally these people are suitable for the use of health care oxygen machine)
