In ACLS, what is the recommended chest compression rate during CPR?

• A. 60-80 compressions per minute
• B. 100-120 compressions per minute
• C. 120-140 compressions per minute
• D. 80-100 compressions per minute

Answer: (B)

The recommended chest compression rate during CPR, which is 100-120 compressions per minute, is crucial because it optimizes blood flow to vital organs during cardiac arrest. This rate has been established to ensure that chest compressions are effective in maintaining sufficient circulation, particularly to the heart and brain.

Research indicates that compressions at this rate help maintain a balance between delivering adequate blood flow and preventing excessive fatigue among the rescuer, which is essential for sustaining high-quality CPR. Additionally, this range aligns with the physiological needs during an emergency, allowing for effective heart compression and the maintenance of coronary perfusion pressures.

Adhering to this guideline can significantly impact the chances of survival and neurological outcomes for the patient, underscoring the importance of proper training and adherence to established protocols in emergency situations.
