Oxygen generator for emergency coronavirus use

Question for practical people out there.

Say your hospitals are swamped. No beds. No ventilators available. No oxygen available due to nationwide shutdown. You need oxygen to treat your family or perhaps yourself. It's your last chance to prevent death.

You have electricity, 12V. You have water and some pieces of metal. You can generate oxygen using electrolysis.

How big of an electrolysis cell do you need to build to generate enough oxygen to keep someone with breathing difficulties alive?

What about generating it chemically?

Someone might need oxygen over the course of days. That means you need a constant supply of chemicals.

Electrolysis would be constant, providing you can generate enough.

Materials available

Tin cans from prep store. Tinsnips.
Plastic water bottles, various sizes
Wire. Rivets/screws.
12V source
Epoxy resin

Let's make this!

First question. What's a typical oxygen flow rate for someone being treated in ICU for breathing difficulties?
