As we age, the physiological functions of the human body begin to degenerate. The heart and brain often lack blood and oxygen, which is very prone to senile diseases, such as high blood pressure, diabetes, or senile dementia. Therefore, appropriate oxygen inhalation for the elderly is beneficial. Oxygen inhalation has a certain effect on slowing down the aging of the human body and preventing the occurrence of senile diseases. So what size of household two flowmeter oxygen concentrator do the elderly need to buy for oxygen inhalation?

When choosing two flowmeter oxygen concentrator suitable for the elderly, you should refer to the following points.

1. In terms of oxygen flow
It is generally recommended that people in need of treatment, especially the elderly, buy a larger flow model, such as a 5L machine. The adjustable flow rate of the 5L machine is 0-5L/min, which is suitable for a wider range of people. Even if the oxygen concentration is attenuated in the long-term use of the oxygen machine, it can still meet the treatment needs of most patients. In addition, the 5L oxygen generator can be used with a ventilator.

2. Regarding the stability of oxygen concentration
It can operate continuously for 24 hours, and the oxygen concentration can always be maintained above 90%, which is a necessary condition and the standard for medical-grade two flowmeter oxygen concentrator. Do not buy the so-called health care machine, which has no therapeutic effect.

3. Noise
The elderly sleep lightly and too much noise affects their sleep. If conditions permit, you can buy an ultra-quiet two flowmeter oxygen concentrator.

Finally, we must remind consumers, especially the elderly, that there are many brands of household oxygen concentrators on the market. Many brands deceive consumers and make false propaganda. The 1L-2L health care machine that sells for only 1,000 yuan also claims that 5L-10L is adjustable. It is recommended not to consider such a product.
