New Delhi: Because the second COVID-19 wave has wreaked havoc within the nation, leaving many gasping for breadth, oxygen concentrators are in excessive demand.
The novel coronavirus is principally a respiratory illness that impacts our lungs and in extreme circumstances may cause oxygen ranges to drop to dangerously low ranges, making the illness deadly for the affected person.
An individual’s oxygen degree is measured by oxygen saturation, identified briefly as SpO2. “This is a measure of the amount of oxygen-carrying haemoglobin in the blood. A healthy individual with normal lungs, will have an arterial oxygen saturation of 95% – 100%,” says Ministry of Well being and Household Welfare.
In line with the newest pointers for COVID-19 sufferers, issued by the Ministry of Well being and Household Welfare, an oxygen focus lower than or equal to 93 p.c would require hospital admission. And if the oxygen ranges drop under 90 p.c, it’s categorized as a extreme illness, requiring admission in ICU.
Sufferers with acute drop in oxygen ranges require Oxygen remedy or supplemental oxygen for medical therapy. Liquid oxygen and oxygen concentrators amongst different instruments are used to offer supplemental oxygen to COVID sufferers.
Whereas there’s a scarcity of liquid oxygen for treating COVID sufferers, many individuals are turning to oxygen concentrators for oxygen remedy because the oxygen tanks have to be refilled however an oxygen concentrator can work 24 x 7.
How do Oxygen Concentrators work?
Atmospheric air has roughly 78 p.c nitrogen and 21 p.c oxygen, so an oxygen concentrator takes in ambient air and will increase the oxygen focus, by filtering out and throwing away nitrogen.
When must you use an Oxygen Concentrator?
“Oxygen concentrators can be used only in moderate cases of COVID-19, when the patient experiences drop in oxygen levels, where the oxygen requirement is a maximum of 5 litres per minute,” shares Professor and Head of Division Anaesthesia, B. J. Medical School, Pune, Prof. Sanyogita Naik to the Press Data Bureau (PIB).
The physician additionally shared that the oxygen concentrators are additionally very helpful for sufferers experiencing post-COVID issues which necessitate oxygen remedy.
Can we use Oxygen Concentrators on our personal?
No, we can not. “Patients with moderate pneumonia induced by COVID-19 – with oxygen saturation less than 94 – can benefit from supplemental oxygen given through oxygen concentrator, but only till they get hospital admission. However, patients using it themselves without suitable medical advice can be harmful,” shares Dr Chaitanya H. Balakrishnan, Covid Co-ordinator, St. John’s Medical School Hospital, Bangalore to PIB.
“So, till you get a bed, oxygen concentrator can be beneficial, but definitely not without guidance from chest physician or internal medicine specialist. It also depends on patients’ pre-existing lung conditions,” he additional added.
