The Quality explanation includes which items?

The Quality explanation includes which items?

• A. Rate, depth, and recoil; Minimizing interrupt; Switching compressors; Avoiding excess ventilation; Use of a feedback device.
• B. Time to first compression; Time of first shock; CCF > 80%; Minimizing preshock pause; Early EMS response time.
• C. Team roles and communication.
• D. Equipment readiness.

Answer: (A)

High-quality CPR centers on how well chest compressions are performed, because effective compressions directly drive blood flow to the heart and brain. The best answer includes keeping the compression rate within the recommended range, achieving adequate depth, and allowing full chest recoil, since these factors determine how much blood is circulated with each push. Minimizing interruptions is crucial because every pause reduces perfusion pressure and cerebral blood flow. Regularly switching compressors helps maintain consistent depth and rate as fatigue sets in, preserving quality throughout the resuscitation effort. Avoiding excessive ventilation is also important; over-inflating the chest increases intrathoracic pressure and can impede venous return, undermining coronary and cerebral perfusion. Using a feedback device supports real-time monitoring of rate, depth, and pauses, helping practitioners stay on target. Other items mentioned focus more on timing metrics, team roles, or equipment readiness, which are important for overall outcomes but do not define the core techniques of delivering high-quality chest compressions.
