What is the compression-to-breaths sequence for an adult when two rescuers perform CPR?

Explanation:
In adult two-rescuer CPR, the cycle is 30 chest compressions followed by 2 rescue breaths. This balance prioritizes delivering blood flow to vital organs while still providing enough oxygen via breaths. The chest compressions should be about 2 inches (5 cm) deep and delivered at a rate of 100–120 per minute, with minimal interruptions, and the two rescuers switch roles about every two minutes to prevent fatigue and preserve compression quality. One rescuer delivers breaths using a bag-valve mask or other device, while the other continues chest compressions, then they repeat the cycle. The other options don’t fit because the 15:2 ratio is used for pediatric two-rescuer CPR, not adults; 20 compressions to 2 breaths would reduce perfusion; and 30 compressions to 1 breath would provide too little ventilation for the patient.
