In CPR, which component is performed first according to the CABD sequence?

• A. Airway
• B. Breathing
• C. Compressions
• D. Defibrillation

Answer: (C)

In CPR, sustaining circulation is the highest priority because delivering blood flow to the heart and brain immediately after cardiac arrest is what keeps them viable while spontaneous rhythm returns. In the CABD sequence, the first action is chest compressions. They generate forward blood flow and help preserve brain function and other vital organs until normal heart activity resumes. Airway and breathing come next to ensure oxygen reaches the blood that’s being circulated. Defibrillation, when indicated, is addressed after establishing circulation and ventilation, so you don’t delay the critical step of keeping blood moving.
