How to choose the right oxygen concentrator

19 Aug 2022

More and more people are now paying more attention to the prevention and treatment of respiratory diseases. Winter is the season of high incidence of respiratory diseases, respiratory tract is easy to be cold stimulation, human resistance to decline and lead to virus invasion. Many patients with lung disease, three high population, pregnant women, stay up late to work overtime sitting office workers, will appear the situation of hypoxia. There are often palpitations, accelerated heartbeat or too slow, dizziness, headache, fatigue, and even chest tightness discomfort breathing difficulties. At this time, you can choose the appropriate home oxygen concentrator for oxygen therapy and oxygen health care.

How to choose the right oxygen concentrator

How to choose the oxygen concentrator that can be used in daily life?

1. Continuous oxygen supply time Continuous 24 hours and 365 days stable oxygen supply.

2. Oxygen flow rate refers to the air output per minute of the oxygen concentrator. For example, the air output per minute of a 3-liter oxygen concentrator can reach 3 liters. In the machine model can be divided into 1 liter, 3 liters, 5 liters. 3 liter oxygen concentrator: suitable for supplemental oxygen for health care groups and patients with minor lung diseases. 5 liter oxygen concentrator: Suitable for people with higher oxygen requirements and patients with severe lung disease.

3. Oxygen concentration and oxygen output of the national standard 3 liters of flow is greater than 85%, generally can reach 93%, otherwise do not buy. Oxygen concentration can reach 90%-96% of the quality of oxygen generator or high quality.

4. International certification Whether through the European Union CE, FDA international certification, "CE" mark is a kind of safety certification mark, is regarded as the manufacturer to open and enter the European market passport. FDA is the Video Drug Administration of the United States. It is the international medical review authority, authorized by the United States Congress, the federal government, and the highest law enforcement agency specialized in food and drug administration. Food, drugs, cosmetics and medical devices certified by the FDA are safe and effective for human health. In the United States and nearly 100 other countries, only materials, devices and technologies approved by the FDA can be used commercially.

The working principle of the oxygen concentrator

The air enters the compressor from the intake filter through the box. The air pressurized by the compressor passes through the cooling system and the steam-water separator to the solenoid valve. The solenoid valve controls the air to enter the molecular sieve through the circuit board. Finally, the molecular sieve separates the oxygen and sends it to the oxygen storage tank, and nitrogen is discharged through the nitrogen discharge tank. Finally, the flow meter can be adjusted to use the separated high-purity oxygen.

Applicable crowd of oxygen concentrator

(1)Respiratory diseases: such as chronic bronchitis, bronchial asthma, emphysema, cor pulmonale, etc.

(2)Cardiovascular and cerebrovascular diseases: such as hypertension, arteriosclerosis, coronary heart disease, myocardial infarction, heart rate disorders, angina pectoris, cerebral thrombosis, cerebral hemorrhage and so on.

(3)Altitude sickness and altitude disease, altitude emphysema, altitude brain edema, chronic altitude sickness, altitude heart disease.

(4)Maternal and fetal intrauterine distress.

(5)CPAP or in a sub-health condition.

(6)Acute and chronic hypoxia caused by other reasons: white-collar workers who stay up late and work overtime for a long time, and examinees who study furiously in exams can use oxygen generators.
