Rational choice of the right oxygen concentrator:
1, to choose a low-noise oxygen concentrator (oxygen machine), the noise level is better than 45 decibels, otherwise, it may affect the rest of me and others, especially at night.
2, to choose the compressor exhaust volume is large enough (3.8-4.2m3 / h) of the oxygen generator (oxygen machine), otherwise, long-term operation is easy to wear and tear, resulting in insufficient gas volume and oxygen concentration attenuation. The skin wrist of the compressor is very important, the better the skin wrist of the compressor, the larger the exhaust volume will be, and the quality of the oxygen concentrator will be better.
3, the oxygen concentration of the output of the oxygen concentrator must be greater than 90%, which can be detected by the instrument or the oxygen monitoring device that comes with the machine. You should choose an oxygen concentrator with an unchangeable cumulative timer function in order to provide objective and accurate data for future long-term maintenance and repair and service. Equipped with a cumulative timer is a mandatory requirement of international standards and a reflection of the quality of the product. The service life of the oxygen concentrator (oxygen machine) should be able to guarantee tens of thousands of hours.
4, for respiratory or heart failure, hypoxemia and chronic obstructive pulmonary disease patients, should choose to be able to 24 hours of uninterrupted work in the state of oxygen concentration can still maintain the standard of medical grade oxygen concentrator.
