Read the first 7 Post-Cardiac Arrest Care flashcards as text

  1. What is the recommended target SpO2 range during post-cardiac arrest care to avoid hyperoxia?

    Answer: 94–99%

    Titrating oxygen to maintain SpO2 between 94–99% avoids both hypoxia and the harmful effects of hyperoxia on reperfused brain tissue.

  2. During targeted temperature management (TTM), which physiological effect of cooling must be actively managed?

    Answer: Shivering

    Shivering counteracts cooling efforts and must be suppressed with sedation, neuromuscular blockade, or magnesium sulfate.

  3. A post-arrest patient develops a MAP of 58 mmHg despite 2L of IV fluid. What is the next best intervention?

    Answer: Start vasopressor therapy

    When fluid resuscitation fails to achieve MAP ≥65 mmHg, vasopressors such as norepinephrine should be initiated.

  4. Which ECG finding in a ROSC patient is the strongest indication for emergent coronary angiography?

    Answer: ST-segment elevation in two contiguous leads

    ST-elevation myocardial infarction (STEMI) pattern is a class I indication for immediate percutaneous coronary intervention (PCI) after ROSC.

  5. What is the primary reason arterial line placement is recommended in post-cardiac arrest patients?

    Answer: Continuous, beat-to-beat blood pressure monitoring

    Arterial lines provide real-time blood pressure monitoring essential for titrating vasopressors and detecting hemodynamic instability after ROSC.

  6. Which electrolyte abnormality is most commonly associated with post-resuscitation arrhythmias and should be corrected promptly?

    Answer: Hypokalemia

    Hypokalemia lowers the threshold for ventricular arrhythmias and should be corrected to maintain serum potassium ≥4.0 mEq/L post-arrest.

  7. A post-arrest patient's end-tidal CO2 suddenly drops from 35 to 10 mmHg without a ventilator change. What does this most likely indicate?

    Answer: Re-arrest or severe drop in cardiac output

    A sudden, dramatic fall in EtCO2 during the post-arrest period signals loss of cardiac output, indicating re-arrest or severe hemodynamic collapse.
