What is the recommended range for post-cardiac arrest targeted temperature management?

• A. 28-32°C
• B. 34-37°C
• C. 32-36°C
• D. 36-38°C

Answer: (C)

Targeted temperature management after cardiac arrest aims to protect the brain by lowering metabolic demand and limiting reperfusion injury, while avoiding the risks of deep cooling or fever. The recommended range is 32–36°C, typically maintained for about 24 hours, because this window provides neuroprotection with a safer balance of side effects than deeper cooling or higher temperatures. After the maintenance period, rewarm gradually, about 0.25–0.5°C per hour, to minimize hemodynamic instability and electrolyte shifts. The emphasis is on preventing fever and keeping the patient within this temperature window rather than allowing normal or higher temperatures.
