CPR Post-Cardiac Arrest Care 2

Question 1

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

Accepted Answer

94–99%

Answer

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

Question 2

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

Accepted Answer

Shivering

Answer

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

Question 3

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

Accepted Answer

Start vasopressor therapy

Answer

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

Question 4

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

Accepted Answer

ST-segment elevation in two contiguous leads

Answer

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

Question 5

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

Accepted Answer

Continuous, beat-to-beat blood pressure monitoring

Answer

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