How many cycles of CPR should be performed in 2 minutes?

In the context of performing CPR, the recommended guideline states that high-quality chest compressions should be delivered at a rate of 100 to 120 compressions per minute. Given this rate, in a 2-minute period, the total number of compressions delivered would range from 200 to 240.

To further break this down, each cycle of CPR consists of 30 chest compressions followed by 2 rescue breaths, making a complete cycle last approximately 30 seconds. Therefore, in a full 2-minute span, you could effectively perform approximately 4 cycles of CPR, but factoring in the timing for the rescue breaths and potential pauses, it is practical to estimate around 5 cycles can be achieved within that time frame.

Thus, the correct answer aligns with the current CPR training standards, which advocate for performing about 5 cycles of CPR in 2 minutes. This emphasizes the need for efficiency and adherence to guidelines that enhance the effectiveness of the resuscitation efforts.
