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?

Well Yes

Relevant excerpts from the death saving throw rules...

Regarding stabilization:

The number of both [successes and failures] is reset to zero when you regain any hit points or become stable. . . . A stable creature doesn't make death saving throws, even though it has 0 hit points, . . .

Regarding unstabilization:

If you take any damage while you have 0 hit points, you suffer a death saving throw failure. . . . The creature stops being stable, and must start making death saving throws again, if it takes any damage.

In summary:

• A successful DC 10 Wisdom (Medicine) check will reset the number of failed death saving throws to zero and prevent additional death saving throws until damage is taken.


• Only when that damage is taken do death saving throws commence once more.


• If the character is stabilized once per round, death from ongoing but trivial damage could be staved off indefinitely.

But Actually No

Your question includes the phrase (emphasis mine)

completely mitigate the risk of death from ongoing damage

and also states that the damage is coming from an

animated stone statue

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. 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.

Furthermore—and this kind of goes without saying—if any other sources of damage could possibly impact the unconscious character, this same tangible risk of death will be present
