Death Saves and Cardiac Arrest Protocols

I'm gearing up to run a dnd game for a bunch of paramedics and I thought it'd be fun to incorporate cardiac arrest protocols into death saves. Death Save is now a ROSC1 rollWhen a character reaches 0HP, roll for ROSC: 1d20 >= TN. HP TN 0 11 -1 12 -2,-3 14 -4,-5 16 -6,-7 18 <=-8 20 The roll may be repeated every 2 minutes (2 combat rounds). Magical healing may increase HP no further than zero until ROSC is achieved. It therefore has some utility in reducing the TN, but cannot be solely relied on for resuscitation. ModifiersAdd relevant modifiers to each roll. positive modifiers +1 for effective chest compressions with minimal interruption. CON check every 4 minutes to continue delivering effective CPR +1 for adequate delivery of ventilations (mouth to mouth, BVM2) +2 for any reversible causes addressed. These will mostly require successful INT or DEX checks. Hypoxia: Definitive airway and ventilated with 100% oxygen(intubated, o2 tank, Gust spell, etc.) Hypovolaemia: IV fluids and…
