i think you would be given oxygen therapy, possibly aided by pressure machine if more severe, maybe nebuliser, and poss antibiotics for pneumonia which may accompany.
with specialist physiotherapy to help lung function.
there are well-established methods for treating respiratory problems.
but the problem is if there are many more cases than usual, due to the virus, as there is no spare capacity in uk hospitals, and staff are likely to be absent themselves due to infection.
if it got really bad, ie high numbers needing medical care, there would have to be rationing, based on not who is most ill, but on who is most likely to recover.
so the elderly, ill, weak, immuno-suppressed are rightly worried.
i get annoyed when i hear mostly fit youngish men say, oh its only like the flu, and only the old and ill are at real risk; as if they dont matter. a them and us mentality. i'm alright jack attitude. othering indeed.
everyones health depends on everyone else.
no wonder some of us feel particularly vulnerable, knowing what some people are like, and how hospitals actually function.
please everyone take a wide precautionary approach, and let us do our best, for one and all.
