The official medical conditions are:
Grave Condition (vital signs unstable and in danger of dying)
Critical Condition (in danger of dying but vital signs relatively stable [every other condition means by definition “stable”]
If a PR person says the patient is in stable condition, the next question to ask is “are they in critical condition, good, serious, fair?” Or dead (which their vital signs are stable since all but the temp will remain unchanged). “Dead” is the most stable you will ever be.
If they won’t tell you a condition, then the best thing to report is “we do not know the condition of the victim. The hospital will only say he/she is stabilized”.
