Triage One patient can only live short time is he ignored for one who might be cured

Igros Moshe (Choshen Mishpat II #73.2) Question: There are two patients  but only one can be treated One can only be helped to extend his life for a short time or only remove the pain and rquires emergency services for that. The second can be cured but it is not clear that he needs emergency services in the hospital There is only a single bed in the emergency room. Which one gets treated? What happens if one gets to the hospital first but treatment hasn’t started?
