How to Identify the Oxygen Concentration from an Oxygen Generator

The current trend in the market is the molecular sieve oxygen concentrator. Currently, the oxygen concentration of oxygen concentrators is set by the manufacturer's standards, so there is no national standard, industry standard, or corporate standard for the oxygen concentration at the time of manufacture, which is 93+3%. However, after a period of operation, the oxygen concentration of the concentrator will decrease. But how much decrease is permissible? There is no precise answer yet. Therefore, what users need to know is approximately how much oxygen concentration the oxygen concentrator releases, which is particularly important for your oxygen therapy.

The current method for testing oxygen concentration in oxygen concentrators is commonly chemical testing. As we all know, oxygen supports combustion, and the reaction with organic materials becomes more intense as the oxygen concentration increases. We can use a toothpick with a burning ember and place it at the oxygen outlet of the supply unit. If the toothpick ignites immediately and the flame is bright and white, the oxygen concentration is generally above 90%. If it burns but the flame is white and yellow, the oxygen concentration is usually around 80%. If it's difficult to ignite, the oxygen concentration is already below 70%, and it's time to replace the adsorption tower. Why use a toothpick instead of a cigarette? Because 70% oxygen can still cause a cigarette to burn fiercely, whereas a toothpick is hard to ignite.

After reading the above, you should have a good understanding of how to differentiate oxygen concentrations in oxygen concentrators. Therefore, individuals undergoing long-term home oxygen therapy can also use this method to test oxygen concentrations, ensuring their home oxygen therapy proceeds smoothly and achieves the desired outcomes!
