Post-Cardiac Arrest Care
Initial Assessment and Stabilization
- The American Heart Association recommends confirming return of spontaneous circulation (ROSC) by checking pulse and blood pressure, monitoring for an abrupt sustained increase in end-tidal CO2, or observing spontaneous arterial pressure waves with intra-arterial monitoring 2, 3
- Secure the airway if not already done during resuscitation, using endotracheal intubation or a supraglottic airway device with confirmation via waveform capnography, as recommended by the American Heart Association 3
- Provide ventilation with 1 breath every 6 seconds (10 breaths/min) once an advanced airway is in place, according to the American Heart Association guidelines 3
- Establish IV/IO access if not already present for medication administration, as recommended by the American Heart Association 3
Hemodynamic Management
- Monitor blood pressure continuously and maintain adequate perfusion, as recommended by the American Heart Association 4
- Administer vasopressors as needed to maintain systolic blood pressure and tissue perfusion, according to the American Heart Association guidelines 4, 5
- Epinephrine remains the primary vasopressor for post-arrest hemodynamic support, with a recommended dose of 1 mg every 3-5 minutes as needed, as stated by the American Heart Association 4, 5
- Avoid high-dose epinephrine as it provides no benefit over standard dosing, according to the American Heart Association 5
Oxygenation and Ventilation
- Titrate oxygen to maintain arterial oxygen saturation of 94-98% to avoid both hypoxemia and hyperoxemia, as recommended by the American College of Cardiology 1
- Maintain normocapnia (normal CO2 levels) by adjusting ventilation parameters and monitoring with waveform capnography, according to the American Heart Association guidelines 3
- Avoid excessive ventilation which can increase intrathoracic pressure and decrease cardiac output, as stated by the American Heart Association 3
Temperature Management
- Begin targeted temperature management for patients who do not follow commands after ROSC, as recommended by the American Heart Association 1
Diagnostic Assessment
- Obtain a 12-lead ECG to identify potential cardiac causes of arrest, particularly ST-elevation myocardial infarction, as recommended by the American College of Cardiology 1
- Consider urgent coronary angiography and percutaneous coronary intervention for patients with suspected cardiac etiology, particularly those with ST-elevation, according to the American Heart Association guidelines 4
- Obtain laboratory studies including arterial blood gases, electrolytes, glucose, complete blood count, and cardiac biomarkers, as recommended by the American College of Cardiology 1
- Monitor for and treat seizures, which are common after cardiac arrest, according to the American Heart Association guidelines 4
Addressing Reversible Causes
- Systematically evaluate and treat potential reversible causes of cardiac arrest (the "H's and T's"), as recommended by the American Heart Association 3, 1
- Hypovolemia: Administer IV fluids, according to the American Heart Association guidelines 3, 1
- Hypoxia: Ensure adequate oxygenation, as recommended by the American Heart Association 3
- Hydrogen ion (acidosis): Correct with adequate ventilation, according to the American Heart Association guidelines 3
- Hypo/hyperkalemia: Check and correct electrolytes, as recommended by the American Heart Association 3
- Hypothermia: Warm if accidental hypothermia was the cause, according to the American Heart Association guidelines 3
- Tension pneumothorax: Perform needle decompression if suspected, as recommended by the American Heart Association 3
- Tamponade (cardiac): Consider pericardiocentesis, according to the American Heart Association guidelines 3
- Toxins: Administer specific antidotes if available, as recommended by the American Heart Association 3
- Thrombosis (pulmonary): Consider thrombolytics or mechanical intervention, according to the American Heart Association guidelines 3
- Thrombosis (coronary): Evaluate for acute coronary syndrome, as recommended by the American Heart Association 3
