As India faces a shortage of hospital beds amid a record surge in coronavirus infections, several infected people have had to seek treatment at home. Shortage of oxygen cylinders has given rise to increasing sale of oxygen concentrators. But what are they?
newsbytesapp.com/news/india/cor…
An oxygen concentrator uses ambient air to concentrate oxygen. It can dispense 90-95% pure oxygen by compressing it from atmospheric air, which comprises 21% oxygen and 78% nitrogen. The air is filtered through a sieve, and then the nitrogen is released back into the air. #Oxygen
The oxygen is concentrated inside the device and a pressure valve helps regulate the supply, ranging from 1-10L/min. Experts say, 90-95% pure oxygen generated by oxygen concentrators is good enough for mild and moderate COVID-19 patients with oxygen saturation levels above 85%.
But, this oxygen is not advisable for ICU patients, who benefit from 99% Liquid Medical Oxygen (LMO). Further, concentrators can be attached to multiple tubes to serve two patients; this may raise the risk of cross-infection. #OxygenCrisis #Oxygen #Corona2ndWave #IndiaFightsBack
Unlike oxygen cylinders, that need to be stored and transported in cryogenic tankers, oxygen concentrators are portable and need no special temperature. Cylinders also require refilling, however, concentrators only need a power source to function. #OxygenEmergency #coronavirus
Concentrators can supply 5-10 liters of oxygen per minute and are hence, not suited for critical patients, who may need 40-50 liters per minute. Notably, concentrators cost around Rs. 40,000-90,000 and are more expensive than cylinders (Rs. 8,000-20,000). #Oxygen #OxygenCrisis
But, concentrators are mostly a one-time investment, with little operational cost apart from electricity and routine maintenance. Cylinders, meanwhile, involve refilling costs and transportation. Concentrators can produce oxygen 24hrs a day, 7 days a week, for up to 5yrs or more.

Even as a grim second wave of the coronavirus pandemic grips India and overwhelms its healthcare infrastructure, an inspiring story of recovery has come to the fore from Uttar Pradesh. It’s about 82-year-old Vidya Devi from Alinagar, Gorakhpur. #COVID
newsbytesapp.com/news/india/82-… Image
Vidya Devi won the battle against the fatal infection in just 12 days with the support of her family and their doctor's advice. Her elder son, Hari Mohan, said that her oxygen level had dipped to 79 one day. "Everyone in the family got worried." #Corona2ndWave #Covid19IndiaHelp Image
He said they then asked her to sleep in the "prone" position, adding that it helped improve her oxygen level to 94 in four days. "She is now fully healthy and her oxygen level is 97 these days." #proning #Corona2ndWave #IndiaFightsCorona #IndiaFightsBack

Even as a dreadful second wave of the COVID-19 pandemic ravages India, the AAP-led Delhi government is apparently under-reporting its daily death toll. Harrowing images of non-stop mass cremations in Delhi are being circulated online for the past few days.
newsbytesapp.com/news/india/ove… Image
Report says the Municipal Corporation of Delhi's data shows that 3,096 cremations, as per COVID-19 protocols, were conducted during April 18-24. But, as per the data released by the Delhi government, the total number of coronavirus-linked deaths during the said period was 1,938. Image
Hence, as many as 1,158 deaths may have never made it to official records. In fact, patients who die of COVID-19 at their homes are allegedly not included in the official records. A staff member at the Ghazipur Crematorium told a portal that the allegation holds true. #Delhi Image

When India is battling Covid-19 second wave, former Maharashtra CM Devendra Fadnavis's nephew Tanmay Fadnavis, said to be about 22 years old, got vaccinated. Currently, only those aged above 45 are allowed to be vaccinated against COVID-19 in India.
newsbytesapp.com/news/politics/…
In a tone-deaf manner, Tanmay posted a photo of himself getting the second dose, on Instagram. He was injected at National Cancer Institute (NCI) in Nagpur. He is the grandson of former MLA Shobha Fadnavis, the aunt of the ex-CM. #tanmayfadnavis #DevendraFadnavis #COVID19India
When asked how Tanmay was able to jump the queue, NCI Director Shailesh Joglekar revealed that he took the first jab at SevenHills Hospital in Mumbai. After the picture surfaced, which has now been deleted, Congress leaders seized the opportunity and rightfully slammed Fadnavis.
