In principle, the Portable Oxygen Concentrator With Battery mainly separates and concentrates oxygen from the air through components such as air compressors and molecular sieves. At normal altitudes, the composition of air is relatively stable, containing about 21% oxygen, 78% nitrogen, and a small amount of other gases. At this time, the Portable Oxygen Concentrator With Battery can effectively separate and concentrate oxygen from the air according to its design specifications.
However, as the altitude increases, the atmospheric pressure gradually decreases. For example, the standard atmospheric pressure at sea level is about 101.3kPa, while at an altitude of 3,000 meters, the atmospheric pressure may drop to about 70kPa. This change in air pressure causes the air to become thinner and the number of gas molecules per unit volume to decrease. For the Portable Oxygen Concentrator With Battery, first of all, the air intake may be affected. Due to the decrease in external air pressure, the air compressor may not be able to achieve the intake efficiency at low altitudes when inhaling air.
Secondly, at high altitudes, the partial pressure of oxygen in the air will also decrease. This means that although the proportion of oxygen in the air is still about 21%, the absolute amount of oxygen that can be extracted by the Portable Oxygen Concentrator With Battery is relatively reduced. Just like a "raw material library" with fewer resources, even if the Portable Oxygen Concentrator With Battery works hard, the initial amount of oxygen it can obtain for concentration is less than at low altitudes.
However, some high-end Portable Oxygen Concentrator With Battery will have a certain altitude compensation function. They sense the changes in air pressure through built-in sensors, and then adjust the working parameters of the compressor and the adsorption-desorption cycle of the molecular sieve to ensure a relatively stable oxygen output concentration at high altitudes as much as possible. But in general, as the altitude increases, the oxygen concentration capacity of the Portable Oxygen Concentrator With Battery will still face challenges, and it may not be able to achieve the ideal working state at low altitudes in extremely high altitudes.
