What is the ratio of chest compressions to breaths when providing CPR to an adult?

30 compressions to 2 breaths
15 compressions to 2 breaths
30 compressions to 1 breath
40 compressions to 2 breaths

The correct answer is: 30 compressions to 2 breaths

The correct response is based on the established guidelines for administering CPR to an adult, which recommend a ratio of 30 chest compressions followed by 2 rescue breaths. This method corresponds with the latest science in resuscitation, emphasizing a focus on high-quality chest compressions coupled with minimal interruptions for ventilations. The rationale behind this specific ratio is that it effectively maximizes the potential for blood circulation during cardiac arrest while still allowing sufficient breaths to oxygenate the patient. The emphasis on 30 compressions before giving 2 breaths allows for a more manageable and consistent rhythm for rescuers, making it easier to maintain the recommended compression rate of at least 100 to 120 compressions per minute. This combination is vital for maintaining vital organ perfusion, especially the heart and brain, during a critical situation. Therefore, this method is not only effective but also aligns with the recommended approach for adult CPR, reinforcing its importance in life-saving scenarios.
