Will inhaling oxygen with an oxygen concentrator use up the oxygen in the room?

In recent years, household oxygen concentrators have entered every family and become a necessity for family life. Will inhaling oxygen consume the oxygen in the room? This is a common concern and concern of people who take oxygen. As long as you understand the generation of oxygen and the working principle of the oxygen generator, you will not have such worries.
Today I will share this question with you. First of all, the oxygen produced by the oxygen generator is extracted from the air in which we live through pressure swing adsorption technology. The oxygen concentrator is filled with molecular sieves, which can absorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and purified to become high-purity oxygen. In other words, the molecular sieve oxygen concentrator does not consume the oxygen in the air, it just acts as a porter, moving it from the room to the oxygen concentrator, collecting it and giving it to the oxygen inhaler. The oxygen used by the oxygen inhaler also exists in the ambient air itself. That is to say, whether you use it or not, the oxygen is there. Giving the oxygen inhaler more oxygen will not affect the oxygen in the environment, nor will it be exhausted. oxygen.
In fact, this worry is unnecessary. When not using a household oxygen inhaler, we directly inhale oxygen from the air and emit carbon dioxide, while using a household oxygen inhaler to inhale oxygen also inhales oxygen and emits carbon dioxide. In addition, when we breathe in our daily life, the oxygen we actually inhale is very little, and most of the oxygen is returned to the air through breathing. Using a household oxygen concentrator to inhale oxygen just separates the oxygen in the air to make the oxygen we inhale purer.
Moreover, oxygen inhalers only consume oxygen when inhaling, but not when exhaling. Secondly, the oxygen inhalation environment used by oxygen inhalers - the room, does not need to be airtight, and there is no completely airtight environment. In the process of our oxygen inhalation, as the outside air enters, it will also supplement Oxygen in the room, which can completely balance the oxygen consumed by the oxygen inhaler.
To sum up, oxygen inhalation will not consume the oxygen in the room, please feel free to inhale oxygen!
