How to choose an oxygen concentrator?

Key points when choosing an oxygen concentrator for patients with chronic respiratory disease:

1. necessary conditions

◆ Choose a oxygen concentrator;

◆ The concentration of oxygen generator should be above 90% and stable;

◆ To adjust the flow according to the doctor's prescription (recommended 5 liters and above oxygen concentrator).


2. Low operating noise (recommended noise below 48dB(A))

(Because in home oxygen therapy such as COPD patients need more than 15 hours of oxygen inhalation, it is very important to use it with peace of mind during sleep)

◇ better durability, can be used for a long time

◇ Trustworthy manufacturers


1. Types of oxygen generators:

There are two types of oxygen generators: health care type. Patients with chronic respiratory diseases should choose oxygen generators.

• Oxygen Concentrator for Health Care

Flow: Mainly below 3 liters

Oxygen concentration: below 90% for most products

→ Generally speaking, it is used for healthy people to relieve physical fatigue and oxygen supplement, not for patients with chronic respiratory diseases.

• oxygen concentrator

Flow: more than 3 liters, mainly 5 liters

Oxygen concentration: more than 90%

→ Mainly used as a treatment for patients with chronic respiratory diseases.

Patients with chronic respiratory diseases must choose a oxygen concentrator.


Second, the identification method of operating noise:

According to the national standard, the noise of the oxygen generator is stipulated to be lower than 60dB(A). On this basis, various oxygen generators have various noise levels, and patients with chronic respiratory diseases are recommended to inhale oxygen for more than 15 hours a day. Therefore, it is sometimes necessary to continue to inhale oxygen during sleep, so choose a quiet machine as much as possible.

3. Judgment of durability and reliability:

Patients with chronic respiratory diseases require long-term oxygen therapy. Therefore, when choosing an oxygen generator, it can run continuously for 24 hours, and it is a necessary condition to provide a stable oxygen concentration for a long time.
