Unless you’re underwater or in a hyperbaric chamber, oxygen toxicity isn’t really a big concern, and a cheap oxygen concentrator like the one described above can’t get you close to where problems start. Even if you had a better oxygen concentrator, it doesn’t take any fancy training to add oxygen until 92% saturation or whatever.

Yes, a unit that can only do 5L/minute at 30% probably isn’t dangerous—but I’d still ask a doctor what treatment protocol to use and how to monitor.
