As India is battling the huge spike in Coronavirus instances throughout the second wave and there’s an elevated demand for oxygen with hospitals struggling to meet the demand for oxygen main to the dying of sufferers in a number of instances, the demand for oxygen concentrators can be witnessing an increase.
What is an oxygen concentrator?
Oxygen concentrators dispense oxygen in virtually precisely the identical means that oxygen tanks do, delivering oxygen instantly to the affected person through the identical nasal cannula or oxygen masks. However, the place oxygen tanks include a hard and fast quantity of pressurized oxygen, concentrators gather oxygen from the surrounding air, focus it, after which ship it to the affected person, eradicating the want for alternative or refilling.
“They work on the principle of ‘rapid pressure swing absorption’ which is where the nitrogen is removed from the air using zeolite minerals which absorb the nitrogen, leaving the other gases to pass through and leaving oxygen as the primary gas. Once the oxygen is collected, the pressure then drops which allows nitrogen to desorb and be expelled back into the air through silencers,” Sunil Khurana, MD and CEO at BPL Medical Technologies in New Delhi, instructed IANS.
“Oxygen concentrators do not have limitations of refilling. It takes oxygen from the air itself, which enables unlimited supply of oxygen till electricity is available. Oxygen concentrator is a more safe option compared to the Oxygen cylinders, because cylinders can sometimes leak and oxygen saturation increases the risk of fire,” Dr Ravi Shekhar Jha, HOD and Senior Consultant Pulmonology, Fortis Escorts Hospital, Faridabad instructed IANS.
Oxygen concentrators produce up to 95 per cent pure oxygen. It additionally has in-built oxygen sensors which may point out if purity ranges go down, Khuranna mentioned.
When ought to an oxygen concentrator be used?
“In the case of Covid-19 patients, who feel breathless when their oxygen saturation drops below 94 per cent, then he or she must be put on Oxygen Therapy immediately to avoid damage to other body parts. Oxygen concentrators play an important role as they supply supplemental oxygen to patients via nasal cannula,” Sunil Khurana defined.
Oxygen concentrators are broadly used for oxygen provision in healthcare functions, particularly the place liquid or pressurised oxygen is just too harmful or inconvenient, corresponding to in properties or in transportable clinics.
Oxygen concentrators are transportable and straightforward to use and are thus higher than oxygen cylinders. Although at Rs 40,000-Rs 90,000, they’re costlier than cylinders (Rs 8,000-20,000), they require very minimal upkeep.
The solely upkeep value is energy consumption and the disposable filters and sieve beds that want to get replaced over years of utilization, Khurana mentioned.
Precautions to take while utilizing an oxygen concentrator
While oxygen concentrator gadgets can be utilized at the comfort of sufferers below the supervision of medical doctors or healthcare staff, the stand-alone cylinder wants to be refilled and wishes utmost care and monitoring as there are probabilities of leakage and might trigger fireplace accidents.
Types of oxygen concentrators?
Concentrators are additionally accessible in a number of types, providing bigger fashions to be used at house or in the hospital in addition to extra compact fashions good for touring and transferring out and about and the good half is which you can get oxygen concentrators on Amazon.
There are two forms of concentrators accessible in the market— steady stream and pulse dose. Continuous stream oxygen supplies the identical stream of oxygen each minute until it’s turned off regardless of whether or not the affected person is respiration it in or not, while pulse dose oxygen concentrator detects respiration sample and dispenses oxygen when it detects inhalation, in accordance to Indian Express report.
Importers and Manufacturers in India
Common importers and producers in India are Phillips, BPL Medical Technologies Ltd, Invacare, AirSep company, SS Technologies, Oshocorp Global Pvt Ltd, Medtronic, Inogen, Nidek Medical, Chart Industries.
Things to maintain in mind earlier than shopping for an oxygen concentrator
Normal air could have 21 per cent oxygen. Concentrator sucks atmospheric air, filter nitrogen and different gases and compresses remaining oxygen dispense it via the cannula. Indian Express report says that “If f 1 litre oxygen is provided to the patient through the concentrator, the oxygen percentage (or fraction of inspired air) in lungs rises to 24 per cent, with 2 litres it rises to 28 per cent and with 10 litres it rises to 60 per cent. Depending on need, the litres of oxygen per minute have to be regulated.”
You ought to take a doctor’s recommendation earlier than giving oxygen to a persistence. You ought to all the time maintain a pulse oximeter with you. ‘Oxygen concentrators can supply between 0.1 litres per minute (LPM) to 5 to 10 LPM. A concentrator has 92-95 per cent pure oxygen,’ learn the report.
Recently, the authorities permitted the import of oxygen concentrators for private use, via publish, courier or e-commerce portals below the present class. However, this exemption for private use is barely allowed for a interval until July 31, 2021, in accordance to a notification of the Directorate General of Foreign Trade (DGFT).
“Import of goods, including those purchased from e-commerce portals, through post or courier, where customs clearance is sought as gifts, is prohibited except for life saving drugs/ medicines/ oxygen concentrators and rakhi (but not gifts related to rakhi),” the notification mentioned.
