Twice a day, New Delhi health worker Kamal Kumari receives a flurry of WhatsApp messages from coronavirus patients, containing either a two-digit reading from a tiny medical device or a photo of its glowing display. She scans the numbers from the 1,000 rupees ($13) oxygen monitor, known as a pulse oximeter, checking to ensure they are all above the prescribed 95 mark and then notes them down in her logbook. "When we didn't have this, we wouldn't know about their oxygen levels," said Kumari, explaining how her team would worry about patients' conditions rapidly worsening when India's capital was badly short here of hospital beds. "Now we can find out in time and safely refer patients to the hospital."
