Post-Cardiac Arrest Care Algorithm

When to Use This Algorithm

Use this algorithm when a patient has achieved ROSC after experiencing cardiac arrest. Immediate and systematic post-cardiac arrest care is crucial for improving survival and neurological outcomes.

Steps in the Algorithm

1. Manage Airway
   • Ensure early placement of an endotracheal tube.
   • Prioritize securing the airway to maintain adequate ventilation and oxygenation.
2. Manage Respiratory Parameters
   • Start at 10 breaths per minute.
   • Target oxygen saturation (SpO2) between 92%-98%.
   • Maintain arterial carbon dioxide pressure (PaCO2) between 35-45 mm Hg.
3. Manage Hemodynamic Parameters
   • Aim for a systolic blood pressure >90 mm Hg.
   • Maintain mean arterial pressure (MAP) >65 mm Hg.
   • Use vasopressors or inotropes if needed to achieve target blood pressure and MAP.
4. Obtain 12-Lead ECG
   • Perform an ECG to assess for any signs of myocardial infarction or other cardiac issues.
   • Look for ST-elevation myocardial infarction (STEMI) or other significant findings.
5. Consider Emergency Cardiac Intervention If:
   • STEMI is present.
   • The patient has unstable cardiogenic shock.
   • Mechanical circulatory support is required.

Neurological Assessment

• Does Patient Follow Commands?
  • Yes:
    • If the patient is awake and follows commands, proceed with other critical care management.
  • No:
    • If the patient is comatose, initiate targeted temperature management (TTM).
    • Obtain a brain CT scan to assess for any cerebral damage or other neurological issues.
    • Monitor with electroencephalography (EEG) for seizures or other abnormalities.
    • Continue other critical care management protocols.

Evaluate and Treat Rapidly Reversible Etiologies

• Identify and Treat Underlying Causes
  • Assess for and address any reversible causes of the cardiac arrest, such as:
    • Hypoxia
    • Hypovolemia
    • Hydrogen ion (acidosis)
    • Hypo/Hyperkalemia
    • Hypothermia
    • Tension pneumothorax
    • Tamponade (cardiac)
    • Toxins
    • Thrombosis (pulmonary or coronary)
• Expert Consultation
  • Involve relevant specialists for consultation and continued management of the patient’s condition.

Key Takeaways

Effective post-cardiac arrest care involves maintaining airway, respiratory, and hemodynamic parameters, performing a thorough neurological assessment, and addressing any reversible causes of the arrest. Early and aggressive management is essential to optimize outcomes and reduce the risk of complications.
