It is crucial to speak with a doctor before purchasing an oxygen concentrator to determine how much oxygen the patient needs each litre. Before making the purchase, a person should take the following factors into consideration, say medical and business experts:
- Checking an oxygen concentrator's flow rate capabilities is one of the most crucial things to keep in mind when making a purchase. The oxygen's ability to move from the oxygen concentrator to the patient is measured by flow rate. L/min is the unit of measurement for flow rate (LPM).
- The oxygen concentrator's capacity needs to be greater than what you need. If you need a 3.5 LPM oxygen concentrator, for instance, you should purchase a 5 LPM concentrator. In the same way, if you need a 5 LPM concentrator, you should get an 8 LPM machine.
- Check the oxygen concentrator's number of filters and sieves. The quantity of sieves or filters used in a concentrator determines the quality of the oxygen it produces. The concentrator's output of oxygen must be 90–95% pure.
- Power consumption, mobility, noise levels, and warranty are a few more variables to take into account while choosing an oxygen concentrator.
