Arushi Chaddha's father was dying. The oxygen supply of the hospital, like in hospitals across Delhi, was running on fumes. Most people knew, or knew of someone who had died. Her only hope was the kindness of strangers. On April 23, at 11.30 am, Chaddha posted on Instagram: "Lungs damaged. Oxygen level dropped to 70. Hospital is refusing to keep my father for more than a couple of hours due to the shortage of medical oxygen. My father will die." In a short while, her DM was inundated with messages offering leads. One such message was from Suhail Shetty, who took down Chaddha's details and made several phone calls to his friends and relatives to get an oxygen concentrator. On April 25, at 2.20 am, he managed to arrange one.
