That is pure triage. The ethical issues it raises is who do you save? The discussion in NY was when all else failed, toss a coin. This was told on a video grand rounds discussion on what happened in NY. It was by the doctor who figured out how to use a ventilator for two carefully matched patients. Never been done before and many issues were discussed. They used informed consent.

: the sorting of and allocation of treatment to patients and especially battle and disaster victims according to a system of priorities designed to maximize the number of survivors. 2 : the sorting of patients (as in an emergency room) according to the urgency of their need for care.

The issues raised are what sorting decisions are used and who decides. Age, disability, comorbidity, race, gender, income, insurance, etc.
