In the case of cardiac arrest, high-quality CPR is crucial because:

it increases the chances of the AED delivering a shockable rhythm
it helps prevent brain damage by supplying oxygen-rich blood to the brain
it ensures that the victim will not regain consciousness
it substitutes for the use of an AED

The correct answer is: it increases the chances of the AED delivering a shockable rhythm

In the case of cardiac arrest, high-quality CPR is crucial because it increases the chances of the AED delivering a shockable rhythm. High-quality CPR helps maintain blood flow to the heart and brain, increasing the likelihood that the heart may respond to an AED shock with a shockable rhythm like ventricular fibrillation. This is essential for the successful restoration of a normal heart rhythm and the victim's survival.
