What is the rate of CPR in breaths and compressions?

6 breaths and 110 compressions in a minute
8 breaths and 100 compressions in a minute
10 breaths and 120 compressions in a minute
5 breaths and 130 compressions in a minute

The correct answer is: 6 breaths and 110 compressions in a minute

The appropriate rate of CPR consists of a specific combination of chest compressions and rescue breaths. The current guidelines recommend a compression rate of 100 to 120 compressions per minute, which aligns with the choice indicating 110 compressions per minute. The recommended ratio of breaths to compressions for adults who are unresponsive and not breathing normally is usually around 30 compressions followed by 2 breaths, which translates to a total of 6 breaths in about 1 minute of CPR when using a cycle method. Therefore, while the understanding of breaths is based on the standard approach of providing 2 breaths after every 30 compressions, the guideline allows practitioners to focus more on the compressions while still offering regular rescue breaths. The choice indicating 6 breaths and 110 compressions effectively mirrors the correct principles of CPR practice as per the most recognized guidelines, making it the correct answer. This comprehension is not just about memorizing numbers; it emphasizes the importance of the compressions in maintaining blood circulation while the breaths provide oxygen, showcasing the balance needed in effective CPR delivery.
