Post-cardiac arrest care refers to comprehensive ICU management provided after successful resuscitation from cardiac arrest. Although return of spontaneous circulation is a critical milestone, it marks the beginning of a complex phase of critical illness characterized by brain injury, myocardial dysfunction, systemic inflammation, and risk of recurrent arrest. ICU care is essential to optimize neurological recovery and survival.

Following cardiac arrest, patients often remain unconscious with unstable cardiovascular and respiratory function. Brain injury due to lack of oxygen is a major determinant of outcome. ICU management focuses on maintaining optimal oxygenation, blood pressure, and temperature to protect neurological function.

Targeted temperature management, controlled ventilation, and careful sedation are used to reduce secondary brain injury. Continuous monitoring allows early detection of complications such as arrhythmias, seizures, and organ failure. Cardiac function is supported with medications and advanced monitoring.

Post-cardiac arrest patients frequently require mechanical ventilation, renal support, and nutritional therapy. Multidisciplinary ICU care ensures coordinated management of complex physiological disturbances.

High-quality ICU care following cardiac arrest significantly improves survival and long-term neurological outcomes.
