In rural or wilderness settings, which scenario justifies termination of resuscitation in the field without medical control?

• A. No return of pulse despite >20 minutes of CPR
• B. Transport time to ED >40 minutes
• C. EMS exhausted and physically unable to continue
• D. All of the above

Answer: (D)

In wilderness EMS, terminating resuscitation in the field is guided by futility and safety. If there is no return of pulse after more than a short, high-quality CPR effort, the chance of meaningful recovery is extremely small, so continuing in the field offers little benefit. When the estimated time to reach definitive care is very long—such as a transport to the emergency department taking well over a half hour—the likelihood that ongoing field CPR will change the outcome diminishes, making termination a reasonable option to conserve resources and prevent prolonged suffering. If the responders are physically unable to continue due to exhaustion, maintaining high-quality CPR becomes unsafe and impractical, and stopping avoids compromising safety and results. Together, these factors reflect situations where field termination is justified, which is why the all-encompassing option is considered correct.
