Drawing on discussion from the British Cardiovascular Intervention Society (BCIS) OHCA focus group, this article summarises five practical considerations for management following return of spontaneous circulation. First, selective conveyance to specialist cardiac arrest centres may be most effective when aligned with the BCIS algorithm, particularly for patients with features suggesting a reversible cardiac cause. Second, early risk stratification with MIRACLE₂ may support decision-making when interpreted alongside specialist clinical judgement. Third, early multidisciplinary team review may improve coherence in a complex condition that often spans cardiology, intensive care, neurology and emergency medicine. Fourth, neuroprognostication is likely to be most robust when delayed appropriately, guided by European Resuscitation Council recommendations and delivered through a structured multimodal multidisciplinary team process.
