What is the difference between medical oxygen concentrator and an oxygen cylinder?

　　A common mistake most people make is to confuse medical oxygen concentrators with oxygen cylinders. Although they have the same purpose of providing oxygen to the patient, they are different from each other. First, there is medical-grade oxygen in the oxygen cylinder, which is basically about 99% concentrated oxygen. Another difference is that the air in the oxygen cylinder is pressurized, so it can be used to provide the patient with a very high flow rate of air. The use of oxygen cylinders can reach a rate of 15 liters per minute.

　　But at the same time, the disadvantage of the cylinder is that it needs to be refilled. Although the oxygen generator cannot provide compressed air, it can run 24x7. The oxygen generator can only provide 5-10 liters of oxygen per minute, which may not be enough for critically ill patients.

　　Where can I buy medical oxygen concentrator?

　　Most websites are safe. However, due to the mismatch between supply and demand at this time, there are many illegal vendors. Some people sell black oxygen generators or resell machines such as humidifiers as medical oxygen concentrators.

　　Therefore, patients and their families need to be extra careful when purchasing medical oxygen concentrators. We recommend that you buy directly from the official website or through its registered sellers.

　　Even if you have no choice but to buy this machine from a stranger, do not prepay. On the contrary, if you can only pay after the machine is delivered to you, or tell the seller that you prefer to choose the machine and pay on the spot.
