DIY hyperbaric chamber

Hello, I would like to build a hyperbaric chamber to help my father recover from a stroke and diabetes.
Examples:

Shortly on the benefits hyperbaric oxygen therapy:

I have a basic shop with a plasma CNC table, and a TIG set up, as well as MIG.
I wanted to hear your thoughts about the materials and design.

I am thinking either a 4mm mild steel, or 3mm stainless steel sheets, welded into a cylinder and reinforced with 3mm flatbar with plug, fillet and butt welds, and a large polycarbonate window with a 4mm polycarbonate panel.

The maximal pressure inside will not exceed 4 bar, so no extreme pressures.
Will 4mm steel / 3mm SS be enough? Can I go even thinner?

The oxygen concentrator and oxygen compressor will cost around 4k, hoping to stay within a 7.5k budget.
Realistic?
Thanks for the comments!

This is not a project that we can help with..
Although the pressure is low it is still a pressure vessel and requires a certified welder and proper inspections.
Also, it is a medical device which is also highly regulated and could do more harm than good if not properly made and tested.
