Oxygen concentrators are divided into models according to the different oxygen output. The common ones on the market are 3L oxygen concentrator, 5L oxygen concentrator and 10L oxygen concentrator. So what is the difference between these three types of oxygen concentrators? How to choose the right oxygen concentrator for the covid-19 patient?
Product division
3L means the oxygen concentration can reach more than 90% under the flow rate of 1~3L, and the oxygen concentration will decrease after the flow rate exceeds 3L.
5L means the oxygen concentration can reach 90% or more under the flow rate of 1~5L, and the oxygen concentration will drop after the flow rate exceeds 5L.
10L 5L is 1~10L flow rate can reach more than 90% of oxygen concentration, the oxygen concentration will drop after the flow rate exceeds 10L.
Difference
3L level is the ordinary oxygen intake.
5L level oxygen output is larger, if the heart and lung function is relatively poor, or mild patients, should be suitable for 5L oxygen machine.
10L oxygen machine is the largest flow rate machine in the whole oxygen machine market, if you use 10L machine, it is generally a more serious lung condition, 5L machine has begun to be insufficient, including carbon dioxide retention, such a situation needs to use 10L machine to go with the ventilator to use.
Purchase advice
If wholesale, it is recommended to purchase inventory. Two reasons
- The current raw materials of copper, metal parts, cartridges, electronic control boards, chips, plastic shells, continue to rise, some materials out of stock serious.
- Time is gold and life.
