Which combination defines determination of death?

Which combination defines determination of death?

• A. Unwitnessed arrest by bystanders and no ROSC after 20 minutes and no AED shocks
• B. Unwitnessed arrest by EMS personnel and no ROSC after 30 minutes of CPR and no AED shocks delivered
• C. Any arrest with no ROSC after 40 minutes
• D. Witnessed arrest with ROSC achieved

Answer: (B)

In death determination, the key is the absence of return of spontaneous circulation after a defined period of ongoing resuscitation. When EMS arrives to an unwitnessed arrest and there has been 30 minutes of continuous CPR with no ROSC and no AED shocks delivered, the chance of achieving ROSC is negligible, so death can be declared according to standard protocol. The other options either use an inappropriate time frame (20 or 40 minutes) or describe a scenario with ROSC already achieved, which would not define death.
