If there is no pulse, the initial CPR sequence is to perform

• A. Call for Help Only
• B. Check Responsiveness Only
• C. Start With Two Rescue Breaths
• D. Start With 30 Chest Compressions and 2 Breaths

Answer: (D)

When there’s no pulse, the body needs blood flow to keep the brain and heart alive. The quickest way to restore circulation is to start chest compressions right away; they act like a manual heart pump, delivering blood to vital organs. Beginning with a cycle of thirty compressions provides a rapid, ongoing flow of blood while you prepare to re-oxygenate. After those thirty compressions, you give two rescue breaths to push air into the lungs and add oxygen to the blood being circulated. This 30:2 pattern strikes a balance between pumping blood and supplying oxygen, which is why it’s the best sequence when you’re aiding an adult with no pulse. If you can, call for help and bring an AED into the scene, but delaying compressions to do so would reduce perfusion. Starting with breaths alone wouldn’t generate circulation, and waiting to act would miss the critical seconds needed to keep the brain and heart perfused.
