What is essential to maintain during high-quality CPR?

• A. Minimize interruptions and maintain effective compressions
• B. Focus on defibrillation
• C. Ventilate aggressively at all times
• D. Take long pauses to assess

Answer: (A)

The main idea is that keeping blood moving during CPR comes from continuous, effective chest compressions with as few interruptions as possible. Each pause in compressions quickly lowers the pressures that drive blood to the heart, brain, and other vital organs, making it harder to sustain life once you resume. So the best approach is to minimize interruptions and keep compressions delivering consistent, adequate depth and rate (about 100–120 compressions per minute with full chest recoil). This focus on uninterrupted, high-quality compressions preserves perfusion throughout the resuscitation effort.

Defibrillation is important when a shockable rhythm is present, but during the CPR sequence, the priority is maintaining steady compressions. Ventilating too aggressively or taking long pauses for assessment disrupts blood flow and reduces effectiveness, which is why those options are not the essential focus.
