Manufacturing oxygen is easy, delivering it to patient is hard: Siddharth Jain, director, INOX Air Products

"If you look at India, there are a total of 70 oxygen production units in the country, but East and West India are producing 32% each. While North, where there is the highest demand, is producing just 13%. So, in order to support North India, oxygen has to move from East and West. But this journey is 1500 kilometres, he said."
