2025 Korean Guidelines for Cardiopulmonary Resuscitation: Part 6. Post-cardiac arrest care.

This guideline summarizes evidence-based post-cardiac arrest care following the return of spontaneous circulation (ROSC) in adults, incorporating updates from the 2025 Korean Guidelines for Cardiopulmonary Resuscitation and contemporary international evidence.

After ROSC, early evaluation should focus on identifying reversible causes.

A 12-lead electrocardiogram should be obtained promptly, with echocardiography and whole-body computed tomography performed when clinically indicated to assess cardiac function and detect noncardiac or occult etiologies.

Hemodynamic management prioritizes adequate organ perfusion and prompt treatment of shock, including active correction of hypotension.
