Which Groups of People Are Suitable for Oxygen Concentrator?

What is an oxygen concentrator?

Oxygen concentrator, also known as a small-scale molecular sieve oxygen concentrator, medical molecular sieve oxygen concentrator, portable oxygen concentrator, etc. Its basic working principle is through pressure swing adsorption (PSA) technology, using air as raw material, without any additives. When connected to power, it absorbs nitrogen and other gases from the air, separating out high purity oxygen (93% ± 3%).Oxygen concentrators generally consist of an oxygen generator, flowmeter, humidifier, and oxygen concentration status indicator. The oxygen concentration status indicator can sound an alarm when the oxygen concentration drops below 82% to prevent users from inhaling oxygen that does not meet concentration requirements.

How to differentiate various types of oxygen concentrators?

Currently, the market offers oxygen concentrator products for health care, medical, and portable uses. The main difference lies in the flow rate and concentration, and generally, oxygen concentrators can be categorized based on the oxygen output per minute into 1L, 3L, 5L, 10L, and other specifications. Consumers can choose based on their needs.

Are household oxygen concentrators really useful?

In medicine, "oxygen inhalation" is referred to as "oxygen therapy". "Oxygen therapy" is a highly specialized treatment method and is not a cure-all. Currently, there is no evidence showing that oxygen has health benefits for healthy individuals. On the contrary, high-flow oxygen inhalation in healthy individuals can cause "oxygen toxicity." Clinically, medical oxygen is used as a treatment for cardiopulmonary diseases, and the flow of oxygen inhalation is prescribed. Generally, the flow rate and suitability need to follow medical advice. According to consumption tips from relevant national departments:oxygen concentrators, apart from medical institutions, can be used as an auxiliary treatment device for environmental or pathological hypoxia.

Who are oxygen concentrators suitable for?

Generally, oxygen concentrators are suitable for the following groups:

• People with lung diseases: asthma, chronic obstructive pulmonary disease (COPD), chronic bronchitis, pulmonary heart disease, pneumonia, pulmonary edema, emphysema, etc.;

• People with cardiovascular diseases: Those suffering from high blood pressure, high blood lipids, coronary heart disease, acute myocardial infarction, angina, heart failure, etc., who cannot efficiently transport blood throughout the body, leading to hypoxia. Oxygen inhalation can effectively alleviate angina and prevent myocardial infarction and sudden death from coronary heart disease;

• People with severe anemia;

• Other diseases caused by hypoxia;

• People in hypoxic environments: such as high-altitude sickness, etc.

Buying tips for oxygen concentrators

Before purchasing an oxygen concentrator, consult a professional doctor to correctly understand the required oxygen absorption time and flow rate for your condition, then choose the appropriate model and use it according to the instructions.

Consumers must choose online or offline channels that have medical device business filing certificates or medical device business licenses for their purchases. The market for oxygen concentrators is currently vast, and consumers should choose products with medical device registration certificates. Do not purchase products without such certificates.

Oxygen concentrators are small equipment products. Consumers may consider choosing brands with a good reputation for after-sales service to ensure future maintenance and service.
