For a 3-liter oxygen generator, the oxygen output flow rate is 1~3 liters, and the "oxygen output concentration" can be stabilized above 90%, reaching the medical-grade standard. For a 5-liter oxygen generator, the oxygen output flow rate is 1~5 liters, and the "oxygen output concentration" can be stabilized at more than 90% of the medical-grade standard.
Second, the 3-liter oxygen generator and the 5-liter oxygen generator are suitable for different people:
3-liter oxygen generator, suitable for mild and moderate respiratory diseases, cardiovascular and cerebrovascular diseases, and people of Grade III and above. The 5-liter oxygen generator is suitable for critically ill patients, people who need to use ventilators, and people who need long-term oxygen inhalation every day for patients with lung diseases such as chronic obstructive pulmonary disease, pulmonary fibrosis, pneumonectomy, lung cancer, pneumoconiosis and silicosis.
Three, three-liter machines and five-liter machines can bear different workloads:
With the oxygen output of 3 liters oxygen generator 1.5 ~ 2.5 liters, the air compressor has already had a certain workload. In this case, continuous operation of 1.5 hours or 24 hours a day will greatly reduce the service life of the compressor and easily lead to machine failure. The 5-liter oxygen generator has a larger displacement and greater margin, and is in a low-load operation state. Although the displacement of the 5-liter compressor is attenuated in the long-term operation, it can meet the minimum requirements of the system and the overall life is longer.

Matters needing attention in using oxygen generator:
1. Patients who buy oxygen generators should read the instructions carefully before using them.
2. When using the oxygen generator, avoid open flame to avoid fire.
3, oxygen generator should be placed smoothly, otherwise it will increase the noise of oxygen generator operation.
4. The water level in the humidifying bottle should not be too high (the water level should be half of the bottle), otherwise the water in the bottle will easily escape or enter the oxygen inhalation tube.
5. When the oxygen generator is not used for a long time, please cut off the power supply, pour out the water in the humidifying bottle, wipe the surface of the oxygen generator clean, cover it with a plastic cover and store it in a dry and sunless place.
6. When the oxygen generator starts to work, don't make the flowmeter float at zero.
7. Pay special attention when filling the oxygen bag with an oxygen generator. After the oxygen bag is full, be sure to unplug the oxygen bag cannula first, and then turn off the switch of the oxygen generator. Otherwise, it is easy to cause the negative pressure of water in the humidification bottle to be sucked back into the oxygen generator, which will cause the oxygen generator to malfunction.
8, in the process of transportation and storage, it is strictly prohibited to put horizontally, upside down, wet or direct sunlight!
