Post Cardiac Arrest Care Algorithm - 2025 Guidelines Coming Soon

Bradycardia acls algorithm

When someone survives a cardiac arrest, the work isn’t done. Post cardiac arrest care can make the difference between recovery and permanent disability. The ACLS Post Cardiac Arrest Care Algorithm provides healthcare professionals with a systematic approach to optimize patient outcomes after return of spontaneous circulation (ROSC).

Understanding this algorithm isn’t just about following steps—it’s about saving lives and preserving brain function. Whether you’re a seasoned emergency physician or preparing for ACLS certification, mastering post cardiac arrest care is essential for delivering quality patient care.

The Post Cardiac Arrest Care Algorithm focuses on four key areas: airway and breathing management, circulatory support, neurological care, and targeted temperature management. Each component works together to give patients the best chance at meaningful recovery.

Understanding the Post Cardiac Arrest Care Algorithm

The ACLS Post Cardiac Arrest Care Algorithm begins the moment you achieve ROSC. This systematic approach addresses the complex physiological changes that occur after cardiac arrest, including post-cardiac arrest syndrome.

Post-cardiac arrest syndrome includes four main components:

  • Brain injury from hypoxia
  • Myocardial dysfunction
  • Systemic ischemia and reperfusion response
  • Underlying pathology that caused the arrest

The algorithm provides evidence-based interventions to address each of these components systematically.

Step 1: Optimize Ventilation and Oxygenation

Proper airway management remains critical after ROSC. The algorithm emphasizes controlled ventilation to prevent both hypoxia and hyperventilation.

Key Actions:

  • Maintain SpO2 between 94-99%
  • Avoid excessive ventilation (hyperventilation can reduce cerebral blood flow)
  • Target PaCO2 of 35-45 mmHg
  • Consider advanced airway if not already in place

Excessive oxygen can cause oxygen toxicity, while insufficient oxygen worsens brain injury. The goal is physiological optimization, not maximum values.

Step 2: Treat Hypotension and Shock

Hemodynamic instability commonly occurs after cardiac arrest. The algorithm prioritizes maintaining adequate perfusion pressure.

Blood Pressure Targets:

  • Systolic BP ≥ 90 mmHg
  • Mean arterial pressure ≥ 65 mmHg

Treatment Options:

  • IV fluids for volume expansion
  • Vasopressors (norepinephrine is first-line)
  • Inotropes if myocardial dysfunction is present
  • Consider mechanical circulatory support in severe cases

Don’t just treat numbers—treat the patient. Look for signs of adequate perfusion like urine output and mental status.

Step 3: Neurological Assessment and Neuroprotection

Brain protection is a primary goal of post cardiac arrest care. The algorithm includes both immediate assessment and ongoing neuroprotective strategies.

Immediate Neurological Assessment:

  • Glasgow Coma Scale
  • Pupillary response
  • Motor response to stimuli
  • Seizure activity monitoring

Neuroprotective Measures:

  • Maintain normoglycemia (140-180 mg/dL)
  • Prevent and treat seizures
  • Avoid hyperthermia
  • Consider targeted temperature management

Early neurological assessment helps guide prognosis and treatment decisions, but avoid premature prognostication.

Step 4: Targeted Temperature Management (TTM)

Temperature control is one of the most important interventions in post cardiac arrest care. The algorithm recommends specific temperature targets based on current evidence.

TTM Protocol:

  • Target temperature: 32-36°C (89.6-96.8°F)
  • Duration: 24 hours minimum
  • Gradual rewarming: 0.25-0.5°C per hour
  • Avoid hyperthermia for 72 hours post-arrest

Monitoring Requirements:

  • Core temperature measurement
  • Shivering assessment and management
  • Electrolyte monitoring
  • Cardiac rhythm monitoring

TTM reduces metabolic demand and may improve neurological outcomes, especially in comatose patients.

Step 5: Identify and Treat Underlying Causes

The algorithm emphasizes finding and treating the root cause of cardiac arrest to prevent recurrence.

Common Causes to Investigate:

  • Acute coronary syndrome (12-lead ECG, troponins)
  • Pulmonary embolism (CT angiography)
  • Electrolyte abnormalities (comprehensive metabolic panel)
  • Drug toxicity (toxicology screen)
  • Tension pneumothorax (chest X-ray, ultrasound)

Emergency cardiac catheterization should be considered for patients with evidence of acute myocardial infarction.

Step 6: Consider Prognostication

Neurological prognostication helps guide family discussions and treatment decisions, but timing is crucial.

Prognostic Factors:

  • Initial rhythm (VF/VT vs. non-shockable)
  • Time to ROSC
  • Neurological examination findings
  • Biomarkers (NSE, S-100B)
  • Imaging studies (CT, MRI)

Wait at least 72 hours after rewarming before making prognostic determinations in comatose patients who received TTM.

Implementation Challenges and Solutions

Implementing the Post Cardiac Arrest Care Algorithm requires coordination among multiple healthcare teams. Common challenges include resource limitations, knowledge gaps, and communication breakdowns.

Solutions for Success:

  • Regular team training and simulations
  • Clear protocols and order sets
  • Multidisciplinary rounds
  • Family communication strategies
  • Quality improvement initiatives

Remember that post cardiac arrest care is time-sensitive. Quick implementation of the algorithm improves patient outcomes.
