India's healthcare system is buckling as a record surge in Covid-19 cases puts pressure on hospital beds and drains oxygen supplies. Families are left pleading for their relatives who are desperately ill, with some patients left untreated for hours. Crematoriums are organising mass funeral pyres. On Friday India reported 332,730 new cases of coronavirus, setting a world record for a second day running. Deaths were numbered at 2,263 in 24 hours. Oxygen crisis Dr Atul Gogia, a consultant at the Sir Ganga Ram hospital in Delhi, told the BBC there had been a "huge surge" in patients, leaving no space in the emergency room. "We do not have that many oxygen points. Whatever oxygen points are there, they're full. Patients are coming in with their own oxygen cylinders or without oxygen. We want to help them but there are not enough beds and not enough oxygen points even to supply them oxygen if it is there," he said. "All our telephone lines are jammed. People are continuously calling the helpline. There is a big rush outside the hospital: there are ambulances parked, patients wanting to get deboarded, but the problem is, there is no space. "We try to mobilise, we try to discharge patients who become stable as early as possible so that we can increase the turnaround, but things are difficult right now." Maharashtra, the worst-hit state in India, faces an oxygen shortfall. In the state capital, Mumbai, at least 13 patients died after a fire broke out in an intensive care unit of a hospital treating Covid patients. Two days earlier, 24 Covid patients died in another part of the state after a leak interrupted the flow of oxygen to their ventilators. On Friday morning, Max Healthcare, which runs 10 private hospitals around Delhi, put out an "SOS" message, saying it had less than an hour's supply remaining at two of its sites. The shortage was later resolved. Three other states - Gujarat, Uttar Pradesh and Haryana - are also facing a critical shortage. The Indian Air Force is being used to lift oxygen tankers and supplies to different parts of the country.
