Oxygen concentrator machine is a commonly used medical equipment in our family. Due to the needs of a large number of respiratory diseases and some hypoxic patients, more and more families use portable oxygen concentrator. Today, I will show you how to choose an oxygen making machine, and what parameters should be paid attention to when purchasing an oxygen concentrator machine?
1. Whether with atomization
Those who need the atomization function should pay attention to choosing the medical oxygen concentrator with atomization function. If you don’t know what type of oxygen concentrator machine you should use, you can consult relevant professionals.
2. Understand the structure of the oxygen generator
In fact, the structure of the new medical oxygen concentrator is very simple, with only two core components, molecular sieve and air compressor. Of course, the oxygen generator also contains other components, including flow regulation systems, air filtration systems, alarm systems, and so on.
3. Two parameters of oxygen concentrator machine: oxygen concentration and oxygen flow
The concentration and flow of oxygen are interdependent. Since the oxygen inhalation method of the oxygen making machine is nasal inhalation, even if the oxygen discharged by the oxygen concentrator machine is pure oxygen, the problem of oxygen dilution is unavoidable when it enters the nostrils.
In medicine, there is a formula for the concentration of pure oxygen inhaled by a nasal suction tube: Inhalation concentration = 21 + 4 × oxygen flow. If the oxygen concentration of the medical oxygen concentrator is high concentration oxygen (>90%), our actual inhaled oxygen concentration is 21+4×1=25% when we inhale at a flow rate of 1L, which is the actual oxygen concentration we inhale. It is 25%, and in order to achieve the purpose of oxygen therapy, our actual inhaled oxygen concentration needs at least 30% oxygen.
Therefore, in order to achieve the effect of oxygen therapy, we need at least 2L of high-concentration oxygen (>90%) to meet the demand, that is, at least 2Loxygen concentrator. (PS: The oxygen concentration of the oxygen concentrator machine decreases as the flow rate increases. When the flow rate reaches 2L, the oxygen concentration can maintain more than 90% of the oxygen generator is called 2L machine).
4. Understand the noise problem of medical oxygen concentrator
For patients who need to use the portable oxygen concentrator for a long time, it is inevitable to use it for a long time, usually more than 8 hours. If the oxygen concentrator is too noisy, it may affect the patient’s sleep quality. For patients with respiratory diseases, sleep Quality is also very important. Therefore, try to choose an oxygen concentrator machine with less noise.
5. Some other component details
Other aspects depend on the flow adjustment system of the best oxygen concentrator and whether the panel operation is convenient. You need to be patient when choosing. There are many types of oxygen concentrators on the market, so when choosing an oxygen concentrator, you need to compare and choose products with excellent quality and high cost performance.
