Ordinary consumers can generally choose a suitable molecular sieve oxygen generator from the following three aspects:
1. Product performance
Whether the oxygen generator has a cumulative timing function, it can provide an objective and accurate basis for future maintenance and services.
Whether the oxygen concentration can still reach the standard (93%±3%) under 24-hour uninterrupted working conditions.
It is necessary to pay attention to the performance of the new machine, but also to pay attention to whether the long-term oxygen concentration during use is stable and long-term operation is reliable.
2. Service system
Can you provide professional oxygen therapy services?
Oxygen is a cardiopulmonary medicine. Oxygen therapy is an important medical method and should be used under the guidance of medical staff or professionals. Failure to use oxygen in a standardized and safe manner will not only not improve the condition, but may also have adverse consequences for users.
Oxygen therapy users need to clearly understand the source of oxygen supply, oxygen delivery method, daily oxygen inhalation time, treatment course, and oxygen flow during rest, activity, and sleep, so as to truly achieve scientific oxygen use.
For patients with chronic obstructive pulmonary disease who are already associated with hypoxemia, they need to inhale oxygen for at least 15 hours throughout the day to make the arterial blood oxygen partial pressure reach at least 60 mmHg in order to obtain the ideal therapeutic effect.
Can we provide professional regular maintenance services?
Indicators such as oxygen concentration and oxygen flow accuracy directly affect the effect of oxygen therapy, and regular maintenance services are essential.
3. Manufacturer
Oxygen concentrator manufacturers have strong strength, strong technical research and development capabilities and high brand gold content, and their product performance and service quality have the most fundamental guarantee. Factors such as company background, registered capital, product launch time, and user reputation should mainly be investigated.
When purchasing a medical oxygen generator, pay attention to the parameter meaning of flow, concentration and oxygen pressure
Foreign countries (including the United States and India) all use 5-liter machines for home oxygen therapy, the reason is very simple
When 5 liters of pure oxygen is inhaled into the lungs, it is diffused and mixed, leaving about 41%, (we know that diving oxygen is 50%). This is the purity that can be suitable for alveolar exchange oxygen for a long time, and the alveolar infiltration is below 50% and 0.06Mpa Oxygen environment will not cause oxygen poisoning. 50% of lung oxygen environment is the most effective oxygen exchange environment in the body without oxygen poisoning. (Generally, low-flow or low-concentration oxygen inhaled into the lungs has been diffused and mixed to be almost the same as air, which is not much different from inhaling air). Excessive oxygen pressure for a long time can damage the alveoli. Foreign countries strictly control the oxygen pressure not to exceed 0.06Mpa.
