The sequence for chest compressions and ventilations during CPR after AED shock is delivered?

• A. 15 compressions to 1 breath
• B. 20 compressions to 2 breaths
• C. 30 compressions to 2 breaths
• D. 40 compressions to 2 breaths

Answer: (C)

After an AED shock, start CPR immediately to restore blood flow and oxygen delivery. For a single rescuer performing adult CPR, the standard sequence is 30 chest compressions followed by 2 rescue breaths, and you repeat this cycle continuously. Do about 100–120 compressions per minute and compress about 2 inches (5 cm) deep, allowing full chest recoil after each push. Give 2 breaths, each about 1 second, with visible chest rise, then resume compressions right away. The goal is to maximize perfusion during the post-shock period while reoxygenating the blood, and this 30:2 pattern is the established rhythm. Other ratios do not align with this adult CPR standard.
