I wouldn't use the words "slaughter" or "inhumanity" because those would mean that the doctors and nurses are inflicting that. However, think clearly. This, much like in war or any other huge disaster with casualties, means that health professionals must employ what is knows as TRIAGE.

Doctors, nurses, and medical staff are trained in triage. This means you decide an order of the "x" amount of people in front of you based on their immediate needs. Not everyone can be saved in every situation. I worked in emergency room triage at Brigham and Women's Hospital in Boston, and while it is is not always easy to make such decisions, they are part of the job of health professionals and those professionals should not be accused of "slaughtering" people.
