What indicates that a resuscitation team performed high-quality CPR?

High-quality CPR is characterized by effective chest compressions that are performed at an appropriate rate and depth, with minimal interruptions. When chest compressions are delivered at the correct rate, which is typically around 100 to 120 compressions per minute, this helps maintain blood circulation to vital organs during a cardiac arrest. Interruption of chest compressions can disrupt blood flow and negatively impact the chances of survival, so consistency and technique are crucial.

Moreover, high-quality CPR also involves allowing complete chest recoil after each compression, which is essential for maximizing blood return to the heart. Providing adequate ventilation is important too, but it should not come at the expense of frequent interruptions in chest compressions. Therefore, option A highlights the fundamental aspects of high-quality CPR that contribute to better outcomes in resuscitation efforts.
