Here is an example of the type of situation that brought up this question. Say a PC has been pinned under the foot of a massive animated stone statue. The PC in question is knocked unconscious by the initial damage and will take additional damage each round, forcing failed death saves, as the statue continues to crush them. A nearby ally succeeds at a Medicine check to stabilize the pinned character so they won't have to make a Death Saving Throw on their next turn. On their next turn the PC being crushed will take a small amount, and suffer a failed death save. An ally will then make another Medicine check, making them stable again. Rinse and repeat.
Under Stabilize A Creature in the 5E PHB it states
If healing is unavailable, the creature can at least be stabilized so that it isn't killed by a failed death saving throw.
This means that with a DC 10 Wisdom (Medicine) check you can stabilize someone even if they have already failed one or two death saving throws. There seems to be nothing to prevent an ally, or allies if the first one fails their Medicine check, from indefinitely eliminating the risk of death in this circumstance with ongoing first aid.
Can Medicine checks be used, with decent rolls, to completely mitigate the risk of death from ongoing damage?
Best Answer
Well Yes
Relevant excerpts from the death saving throw rules...
Regarding stabilization:
Regarding unstabilization:
In summary:
So at a very basic level, these Medicine checks can stave off death indefinitely since successful stabilization will reset the number of failed death saving throws
But Actually No
Your question asks whether the risk of death can be completely mitigated, and unfortunately bad luck can still kill the player because, again from the death saving throw rules:
If the stabilized party member is dealt damage by the statue, he/she will suffer one failed death save. Then if the party member is immediately next in initiative, he/she could roll a 1 on the death save roll and consequently die before anyone has a chance to attempt stabiliztion again.
Additionally, your question states that the damage is coming from an
If the statue is animated, then it might be making attack rolls depending on how sadistic your GM is. If an attack roll crits, the pinned character will suffer two failed death saving throws. And in this case it will, from the unconscious condition rules:
Then a third fail may occur on the character's turn if a party member is unable to stabilize him/her beforehand. Therefore, in this particular scenario (again, if the statue is making attack rolls in spite of low damage output), the character can die in a single round.
