Surely the Government planned for Oxygen supply. I mean this is a basic need during this Pandemic.
Difficult to do anything to increase it within existing infrastructure. It's a bit like your plumbing at home - if I run the dishwasher, then pressure in the shower drops off. If I turned on every tap and flushed the loo, then the pressure out of all of them would be really low.
Hospitals have a giant storage tank of oxygen somewhere out at the back of the car park. But the pipes out of it can only supply the stuff so fast. There's normally plenty of slack in the system, but the system isn't designed for every bed full of patients with the same illness, all of them needing vast amounts of oxygen. Plus CPAP is much more wasteful of oxygen than ventilating someone.
It's a known problem, but short of ripping out all the plumbing and starting from scratch, then what can you do? And that's exactly as disruptive to the running of any hospital as ripping out every waterpipe in your house would be.
