What should be paid attention to during the use of the oxygen concentrator?
- When using an oxygen generator, do not use the oxygen generator near an open flame or while smoking.
- Pay attention to the oxygen concentration, and check your equipment regularly to see if there are any alarms to make sure you get enough oxygen. Too low oxygen concentration will affect the oxygen inhalation effect and the service life of the oxygen concentrator.
- If you need to use an oxygen concentrator due to chronic health problems, pay attention to monitoring the changes in your blood oxygen level at all times
What is the difference between continuous flow and pulsed flow?
What is the difference between continuous flow and pulsed flow?
Pulse flow: During use, it can automatically detect your breathing pressure, release the required oxygen in time when you breathe in, and stop working when you breathe out. Continuous flow releases oxygen regardless of whether it is inhaling or exhaling. At present, the pulse flow mode is mainly used in portable device, so that the use time of the machine is longer.

How does an oxygen concentrator work?
How does an oxygen concentrator work?
A portable oxygen concentrator is a device that separates oxygen from the air and allows you to breathe in the oxygen on an as-needed basis. Portable oxygen concentrators can run on both AC and DC power, and they can be charged by both. This battery charge allows it to bring in air, separate the oxygen from the rest of the air, and deliver it back into your lungs at whatever rate is appropriate for you. Some portable oxygen concentrators offer both continuous flows and pulse dose settings.
The home oxygen concentrator is a device that converts air into oxygen, allowing you to breathe easier. It runs on AC po
