I am sorry about your aunt.
The article was interesting, but overlooked a major factor in the use of ventilators -- personnel to operate them. As I understand it, it takes two years to train an RT and even now, the country does not have enough to adequately staff our needs. From my research, an RT should handle no more than 10 patients in a shift although they would probably stretch that in an emergency -- but at some point, you do exhaust people. So, if I was defense counsel, I think the most effective argument is why purchase the extra 1,000 machines when we have no ability to hire those extra 100 RTs. But this is why lawsuits get filed, so what do I know.
