What is the correct sequence of steps when performing CPR on an adult?

The correct sequence of steps when performing CPR on an adult is to first call for help, then begin chest compressions, followed by rescue breaths. This sequence is critical because immediately calling for help ensures that emergency services are on the way while you initiate lifesaving measures. Starting chest compressions as quickly as possible is essential for maintaining blood circulation to vital organs, particularly the brain and heart. Rescue breaths should be given after the initial set of compressions to provide oxygen to the lungs, but the compressions are prioritized to enhance blood flow during a cardiac arrest situation.

The rationale behind starting with a call for help ensures that additional support and resources arrive, which can be vital in administering advanced care. Initiating compressions right after that helps to maintain blood flow until professional medical assistance takes over. This order of operations is grounded in the guidelines established by organizations such as the American Heart Association, emphasizing the importance of high-quality chest compressions in enhancing survival rates during cardiac emergencies.
