What is the correct compression rate for 2-rescuer CPR?

The correct compression rate for 2-rescuer CPR is 100-120 compressions per minute. This rate is crucial because studies have shown that delivering compressions at this speed is most effective for maintaining blood flow to the vital organs during cardiac arrest. The compressions must be performed at a high enough rate to ensure adequate circulation, as slower rates may not provide sufficient perfusion pressure.

Additionally, performing CPR within this range allows for both effective chest compressions and the ability to take necessary pauses for rescue breaths without losing the effectiveness of those compressions. It strikes a balance between maintaining a high quality of compressions while minimizing interruptions, ultimately enhancing the chances of survival for the patient.

For the other options, rates outside the recommended range could lead to reduced effectiveness of CPR and are not supported by current guidelines.
