1, if you are doing home oxygen therapy, the oxygen concentration of the output of the home oxygen concentrator must be greater than 90%, which can be detected by the instrument or the oxygen monitoring device that comes with the machine.
2. 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 service. Equipped with a cumulative timer is a mandatory requirement of international standards, and is also a reflection of the quality of the product, the service life should be able to guarantee tens of thousands of hours.
3, to choose a low noise home oxygen concentrator, the noise level is preferably less than 45 decibels, otherwise, may affect the rest of myself and others, especially at night.
4, to choose a home oxygen concentrator with sufficiently large compressor discharge (3.8-4.2m3/h), otherwise, it is easy to wear and tear in the long run, resulting in insufficient gas volume and attenuation of oxygen concentration. The skin wrist of the compressor is very important, and it is better to use imported parts.
5, the family oxygen concentrator molecular sieve on the performance of the machine is not as big as imagined, mainly in the molecular sieve adsorption performance and service life, but the molecular sieve filling process is very critical, the molecular sieve tower canisters for the integration of the metal structure, the molecular sieve with a mechanical automatic warning loading of the family oxygen concentrator, the molecular sieve is very important for the performance of the molecular sieve. And with plastic end caps, rivets riveted and hand-filled molecular sieve home oxygen concentrator, its performance is bound to be greatly affected.
6, for respiratory or heart failure, hypoxemia and chronic obstructive pulmonary disease patients, should choose to be able to 24 hours uninterrupted work under the state of oxygen concentration can still maintain the standard medical grade home oxygen concentrator.
7, home oxygen concentrator is a medical device, not health fashion equipment, so the size of the preferences and whether the appearance of the good-looking will vary from person to person, but taking into account the part of the patient's oxygen inhalation time is longer, the need for a long time to continuous power on, we must choose a home oxygen concentrator moderate size, internal structure optimization, heat dissipation of the space of the ideal machine. Only by comprehensively improving the heat dissipation performance can we ensure stable oxygen concentration.
8, to choose to withstand the long-term test of time and through the ISO international and CE European quality system certification of the family oxygen concentrator, the general product on the market after the quality of more than a break-in period, the first two years of performance may be unstable, so pay attention to the product's time on the market and whether to pass the relevant certification.
9, to choose a strong, long-term sustainable development of the home oxygen concentrator (oxygen machine) manufacturers, as well as in the local perfect after-sales service organizations. At present, because the family oxygen concentrator (oxygen machine) varieties, quality varies, manufacturers strength is large, the survival of the fittest, is bound to face the family oxygen concentrator (oxygen machine) industry reshuffle. This point must also attract the attention of users, if the brand is eliminated from the game, it is difficult to guarantee long-term after-sales service after your purchase. What brand of oxygen concentrator is good? I recommend the top ten brands of oxygen concentrator.
10, according to the severity of the disease and the economic ability to choose different grades of home oxygen concentrator, to the "price" and "value" of the unified consideration, to avoid falling into the vicious competition in the vortex of home oxygen concentrator brand. The pursuit of low "price" and ignore the "value". May bring many adverse consequences.
