You can only achieve high chest compression fraction (CCF) by:

• A. Increasing Pauses During CPR
• B. Minimizing Pauses During High-Quality CPR
• C. Focusing On Defibrillation Only
• D. Reducing Compression Depth

Answer: (B)

High chest compression fraction means you spend as much CPR time as possible delivering chest compressions. You achieve this by minimizing interruptions—keep compressions going and shorten or eliminate pauses for rhythm checks, ventilations, and switches of the compressor, while still applying high-quality compressions and coordinating any necessary defibrillation so interruptions are brief. That’s why minimizing pauses during CPR is the best way to reach a high CCF. Increasing pauses would reduce the fraction, focusing only on defibrillation still involves checks and pauses, and reducing compression depth undermines quality even if pauses are minimized.
