In New Zealand you generally can't due for punative damages and lawsuits for medical misadventure are few to non-existent then maybe, but I am sure red tape would still prevent it.
Maybe it could be sold as a non-medical device, call it a "Happy Fun Breathing Simulator" with no explicit purpose and people would stock up on then.
In this situation you're better off just building a lot more of these than you'd need and monitoring. Replace failed units.

It isn't clear that the situation got so bad that they actually needed to make these kinds of hard choices, but the thread links to a document with guidelines in case it's necessary. And apparently those guidelines do include considering age when choosing who not to treat, should such a situation arise.
From a machine translation (the original is Italian) posted further down in that same thread:

It is not a question of making choices merely of value, but to reserve resources that could be very scarce for those who are primarily more likely to survival and secondarily to those who can have more years of life saved, with a view to maximizing of benefits for most people.
