How many cycles are typically performed in two minutes of CPR with a 30:2 rhythm?

• A. 2 cycles
• B. 4 cycles
• C. 6 cycles
• D. About five cycles

Answer: (D)

The idea being tested is how many complete 30:2 CPR cycles fit into a two-minute period. One cycle includes 30 chest compressions plus 2 rescue breaths. At the recommended compression rate of about 100–120 per minute, 30 compressions take roughly 15–18 seconds, and the breaths add a few more seconds. When you include the small pauses between cycles, each cycle lasts about 20–25 seconds. A two-minute span is 120 seconds, which lines up with about five cycles, give or take a cycle depending on pace and pauses. So, “about five cycles” reflects typical practice over two minutes.
