• Oxygen Concentrators are devices which concentrates oxygen from atmospheric air by filtering nitrogen and remaining gases present in it. • Oxygen concentrators are mainly used for patients those who have respiratory issues, or a person who need additional oxygen for a long period and home care patients. • It works based on the principle of Pressure Swing Absorption (PSA), which involves separation of gas species from a mixture of gases under suitable pressure. • Based on this principle, oxygen concentrator uses zeolite particles for separation of gases,At high pressure zeolite particles adsorbs large particles such as nitrogen and oxygen is compressed and move to other end of the valve. • This process of separation will take place in the two adjacent sieve beds between fractions of 10 seconds. These sieve beds are filled with zeolite for filtration. • One sieve bed will collect Oxygen at a time and other one will remove nitrogen through other end of the valve. It will cycled each time. • The Hepa filter and Cabinet filter used in this machine are capable of filtering large particles and minute particles up to a large extend. • On the other hand, we can say oxygen concentrators are replacement of oxygen cylinders. • Since this machine only needs electricity for working, and not need to refill all the time as it in cylinders, it is portable and because of the wheelers provided with machine, patient himself can adjust the movement if he needed. • The lifetime of this machine is more than 3-4 years, which is very much useful for patients in homecare. • Depend on the patient condition we can set the amount of oxygen supply to the patient. • There are 5L to 10 L machines available for the convenient usage of patient. • There are audible alarms indications available for proper maintenance and checking. So there is no need of care taker all the time near the patient.
