"Things have to be done RIGHT NOW because hospitals are vulnerable"
Let's look at that a little more carefully.
What has to be done right now?
I'd say the first thing that has to be done is to find out what has to be done (yes I did spend time living in Ireland ;).
The medics have a term for this, it was used in the article: triage.
Some things can be done quickly but everything can't be done at once because you always have a finite number of people to do it and things have to be done in order: if you think the network needs to be rearranged so as to isolate the more vulnerable equipment then that has to be planned, otherwise you may accidentally fail to do so by missing out on some bridge or you may separate a piece of equipment from other systems it needs to work with. Then you may need to buy more kit which has a lead time.
You can start doing things right now (Starting telling TPTB you're going to need to budget time and money is one). You will actually be able to finish doing very little right now.
Above all you need to avoid the politician's syllogism: something needs to be done, this is something therefore it must be done.
