What is the recommended rate for chest compressions during CPR?

The recommended rate for chest compressions during CPR is indeed 100-120 compressions per minute. This guideline is supported by the latest resuscitation science, which emphasizes that compressions should be delivered at this rate to optimize blood flow and improve chances of survival during cardiac arrest.

Compressions at this optimal rate ensure that there is sufficient time for the heart to fill with blood between compressions, while also maintaining a frequency that is effective in generating blood flow. The target of 100-120 compressions per minute creates a balance between speed and efficacy, which is critical in performing high-quality CPR.

The other options fall outside of this recommended range, either being too slow or too fast, which could hinder the effectiveness of CPR. A slow rate could lead to inadequate circulation, whereas a very rapid rate may result in ineffective compressions and insufficient blood flow during each compression cycle. It's crucial to maintain the proper rhythm and rate to enhance the chances of a successful outcome in cardiac emergencies.
