An oxygen concentrator is a machine that removes nitrogen from a gas source, usually the air, to produce a stream of oxygen that is enriched. It is employed both in industry and as a medical tool for oxygen treatment. Two popular techniques are used: pressure swing adsorption and membrane gas separation. In the former, multiple molecular sieves made up of zeolite minerals remove pressurized nitrogen in rapid cycles.
Medical treatment using oxygen, known as oxygen therapy or supplemental oxygen, is administered to individuals experiencing low blood oxygen levels, carbon monoxide toxicity, cluster headache, or to maintain blood oxygen levels during anesthesia induction. Oxygen therapy is helpful for patients with chronic hypoxemia resulting from severe COPD or cystic fibrosis. Nasal cannula or face mask, high pressure conditions such as endotracheal intubation or hyperbaric chamber, and bypassing the airway via ECMO therapy are all options for delivering oxygen.
Due to the limited availability of oxygen beds and cylinders, doctors are prescribing oxygen concentrators to Covid-19 patients with low blood oxygen levels. Patients are also buying these machines, which have proven to be life-saving for many. Oxygen concentrators work by taking in air from the room and filtering out nitrogen to provide a higher concentration of oxygen to the patient. They come in various types and sizes, from large and stationary to small and portable. Unlike tanks or other containers supplying oxygen, concentrators use electrical pumps to concentrate the continuous supply of oxygen from the surrounding air.
Oxygen Concentrator – how does it work ?
An Oxygen Concentrator is a device that works by taking in ambient air and increasing the concentration of oxygen by filtering out nitrogen. It functions similarly to oxygen tanks or cylinders by supplying oxygen to the body through a cannula, oxygen mask, or nasal tubes. However, the significant difference is that while the cylinders require refilling, the Oxygen Concentrator can work continuously 24 hours a day.
Oxygen concentrators are devices that filter out nitrogen from the air in the room and provide a higher concentration of oxygen for oxygen therapy. They are available in large, stationary models or small, portable versions, and use electrical pumps to concentrate the oxygen from the surrounding air for a continuous supply.
It is essential to note that the FDA has not authorized or approved any oxygen concentrators to be sold or used without a prescription, despite seeing them for sale online.
When using an oxygen concentrator, safety is crucial. You should not use any oxygen product near an open flame or while smoking. Place the concentrator in an open space to avoid overheating, and do not block any vents on the device, as this may affect its performance. You should periodically check the device for any alarms to ensure that you are receiving enough oxygen.
If you have a chronic health condition and are prescribed an oxygen concentrator, it is crucial to contact your healthcare provider if you experience changes in your breathing or oxygen levels, or if you have symptoms of COVID-19. You should not make any changes to the oxygen levels without consulting your healthcare provider.
