Here is another option using the "stealth" approach. I'm praying for you Fren for discernment as to what approach to take - stealth or legal. Of course stealth is only an option if someone can regularly visit your cousin.

Here is the thread where I posted about how the stealth option I used saved the life of my 83 year old father:

Here is a post where in the comments where I referenced the high quality versions of Vit C / D, Zinc, etc. recommended to me by a very based and trusted pharmicist (just look for "MW_Freedom" in the comments in this post for the Web Links I referenced for these:

I not saying you should 100% go with the undercover / stealth approach. Just providing options like other pedes here wanting to help.

Wishing and praying for a good result for your cousin.

Edit: I see where Sabre2th's advice is to leave. I agree with that if your cousin doesn't need supplemental oxygen unless your cousin has access to a supply outside of the hospital. The medical tyrants have created a very difficult situation by making oxygen prescription only (e.g. hospital only for most people who don't have a prescription in advance) and then denying the life-saving treatments. If not in the hospital then good antibiotics and steriods I believe should also be used (I would confirm that if you know a based doctor / medical professional).
