How to choose the right hospital oxygen concentrator for yourself? - Focus on the technical indicators to ensure safety and stability.

When choosing an oxygen generator for a hospital, the technical parameters directly affect patient safety. These points must be given special attention.

First, the purity of the oxygen must meet medical standards. Under normal circumstances, it should be above 93%, and in cases such as neonatal rescue, it should be above 99.5%.

Second, stability is crucial. The purity should not decrease when adjusting the flow rate, and the pressure should be stable at 0.4-0.6 MPa. Otherwise, it may affect the operation of anesthesia machines and respiratory equipment.

Third, impurities need to be controlled well, meeting the quality standards of medical oxygen. (Oil < 0.01 mg/m³, water should be reduced to below the dew point of -40°C, dust < 0.1 μm).

Fourth, the equipment should be able to operate continuously for 24 hours, providing continuous oxygen supply (core components such as molecular sieves should have a lifespan of > 8,000 hours, and compressors should have a lifespan of > 20,000 hours).

Fifth, there should be emergency backup. Small hospitals can choose a main unit with a backup unit, while large hospitals should preferably be equipped with liquid oxygen storage tanks to prevent oxygen supply interruption in case of equipment failure.
