What is the frequency of chest compressions recommended during CPR?

The recommended frequency of chest compressions during CPR is at least 100 to 120 compressions per minute. This guideline is based on research showing that a higher rate of compressions improves the likelihood of maintaining blood circulation and oxygen delivery to vital organs during a cardiac arrest. Compressions at this rate also correlate with better patient outcomes and survival rates.

The emphasis on achieving a minimum of 100 compressions per minute ensures that the compressions are performed at an effective pace to generate adequate blood flow. The range of 100 to 120 compressions offers an appropriate balance that not only maintains the momentum needed for effective CPR but also allows for a rhythm that can be sustained by the rescuer over time without losing efficiency.

In contrast, the other options suggest lower rates that are not advisable. Rates below 100 compressions per minute may not provide sufficient circulation, while anything significantly higher, such as 150 compressions per minute, could lead to ineffective compressions and reduced depth, compromising the overall effectiveness of CPR.
