What are the steps in the CPR sequence for an adult?

• A. Check responsiveness, call for help, begin chest compressions, and deliver rescue breaths
• B. Call for help, begin chest compressions, check responsiveness, and deliver rescue breaths
• C. Deliver rescue breaths, begin chest compressions, call for help, and check responsiveness
• D. Call for help, check responsiveness, deliver rescue breaths, and then begin chest compressions

Answer: (A)

The correct sequence for performing CPR on an adult involves checking for responsiveness, calling for help, beginning chest compressions, and then delivering rescue breaths.

Starting with checking responsiveness is critical because it determines whether the individual is conscious or needs immediate assistance. If the person is unresponsive, calling for help is the next crucial step to ensure that emergency services are on the way while CPR is being initiated.

Once help has been summoned, the focus shifts to performing chest compressions, which are essential for maintaining blood circulation when the heart has stopped. Compressions provide a means to artificially circulate blood to vital organs, particularly the brain and heart. After establishing a rhythm of compressions, rescue breaths can be given to supply oxygen to the patient.

This order follows the established guidelines from organizations such as the American Heart Association, emphasizing the importance of initiating compressions before rescue breaths to maximize the chances of survival until professional medical assistance is available.
