How many cycles of compressions and ventilations are typically performed in 2 minutes of CPR?

In Basic Life Support (BLS), the standard guideline for performing CPR on an adult patient involves a compression-to-ventilation ratio of 30 compressions followed by 2 ventilations. Given the recommended compression rate of approximately 100 to 120 compressions per minute, you can perform about 5 cycles of 30 compressions and 2 ventilations within a 2-minute timeframe.

When you calculate the total compressions in 2 minutes, using a rate of 100 compressions per minute, this results in 200 compressions during that time, which translates to approximately 6.67 cycles (since each cycle consists of 30 compressions). Practically, however, responders often complete around 5 full cycles within 2 minutes while maintaining quality compressions, making option A the most accurate answer regarding typical performance in that duration.

This focus on maintaining a manageable number of cycles within a 2-minute window emphasizes the importance of providing effective and timely care to ensure optimal chances of revival and to minimize fatigue in rescuers.
