Warning: This content might trigger some people The 2nd wave has brought into wide public attention the inadequate supply chain of various essential drugs and equipment, most notably Oxygen. Visuals of desperate families and friends scrambling for the gas will remain a part of our collective memory for a long long time.  Though Oxygen shortage is an issue that came into the fore recently, as a public health consultant, Abhishek Tupe has been engaging with it for years now. In this short and crisp episode, Abhishek breaks down India's Oxygen supply chain for us. Tune in to hear about the three basic ways in which Oxygen is produced. We speak about Oxygen PSA Plants, industrially produced Medical Oxygen (INOX and Linde), and the now ubiquitous Oxygen Concentrators. These three options provide drastically different solutions for what Covid-19 made an almost household problem. They differ in costs, method and point of production and capacity.  (Abhishek Tupe is a Public Health Consultant who has worked with leading Non Profit Organisations across India and Africa.
