NEW DELHI — After the oxygen ran out at an Indian hospital last month and at least 60 children died, who should take the blame?

That question continues to vex the authorities here, and over the weekend, police officials in northern India arrested another suspect: the owner of the company that cut off the hospital’s oxygen supplies because of unpaid bills.

The deaths, during a week in August when oxygen supplies were dwindling and then ran out at Baba Raghav Das Medical College Hospital, a government hospital in Gorakhpur, in Uttar Pradesh State, have stirred outrage in India.

For days, pictures of sick children lingered at the top of India’s major newspapers, and the hospital became a sad symbol of health care in the country. The enormous, overtaxed system has so many people moving through it that mistakes are often not corrected until many lives are lost. And corruption takes its own toll, with money for critical health needs routinely stolen.
