Which statement accurately describes targeted temperature management (TTM) after cardiac arrest?

Targeted temperature management after cardiac arrest aims to protect the brain by carefully lowering body temperature. Cooling to 32–36°C and keeping that range for at least 24 hours in comatose adults after return of spontaneous circulation is the standard approach because it reduces cerebral metabolic demand and limits reperfusion injury, improving neurological outcomes. After this period, rewarming should occur gradually to minimize instability. Warming to 38–40°C would raise temperature and counteract the protective effect. Not using any temperature management misses a proven neuroprotective strategy. Cooling to 28–30°C is more aggressive than typical practice and 6 hours is too short to achieve the benefits and balance risks.
