I sold my wife's jewellery for this. I queue up outside a refill centre & get oxygen. My contact number is available on social media. People can call me up if there's no ambulance. I've been doing this for 15-20 days now & have taken 9 serious patients to hospital: Javed Khan pic.twitter.com/LiEphjHenJ
