Khalsa Aid India on Friday said it will provide oxygen concentrators to Covid-19 patients in Delhi free of cost. The NGO launched a helpline in this regard on Friday evening and had already received over 1,200 requests. Delhi is facing a severe oxygen shortage for the past few days with several hospitals scrambling to shore up their oxygen supplies. “We have decided to give free of cost oxygen concentrators for Covid-19 patients who are in home isolation in Delhi as patients are in dire need of oxygen in government and private hospitals,” said Amarpreet Singh, director, Khalsa Aid Project (Asia Chapter). The NGO, which has recently procured 65 oxygen concentrators, said to avail the service people would have to fill up a registration form, and that patients with "low oxygen saturation levels" would be given priority. Singh added that they will procure more oxygen concentrators in the coming weeks, taking the number to 100. To avail the service people would have to fill up a registration form. Patients with “low oxygen saturation levels” would be given priority. He added to avail the service, “A doctor’s prescription and a picture of oximeter readings will be needed besides other formalities”. Each concentrator will be given to a patient for one week as per the standard operating procedure. If the patient needs the machine for another week, he/she will have to follow the same procedure. “As 1,200 requests have come already in few hours since we launched the helpline number WhatsApp number 9115609005, we are filtering the requests and these concentrators will first be given to the most needy,” he said. “We are trying to procure more machines. The organisation has set up an online registration process to avoid physical contact. The volunteers will deliver these oxygen concentrators in all the parts of Delhi,” said Puneet Singh, a trustee of Khalsa Aid India. Note: An oxygen concentrator is a device that concentrates the oxygen from a gas supply by selectively removing nitrogen to supply an oxygen-enriched product gas stream. One concentrator is available in the market at the cost of Rs 60,000 and onwards.
