What is the order of CPR according to the American Heart Association?
Appeared in: MP CHO-2020
Explanation
- The correct sequence for CPR as per the latest American Heart Association (AHA) guidelines is Compression-Airway-Breathing (C-A-B).
- This change was implemented to prioritize chest compressions and minimize any delay in circulating blood to the vital organs, especially the brain and heart.
- Starting with compressions ensures that the oxygen already in the blood is moved throughout the body, which is the most critical intervention in the first few minutes of cardiac arrest.
- The previous sequence of A-B-C (Airway-Breathing-Compression) is now considered outdated for most cardiac arrest situations.
Why Other Options Were Wrong
- Option A: This represents the old AHA guideline, which was changed in 2010. Prioritizing the airway and breathing before compressions unnecessarily delays blood circulation.
- Option B: This sequence is incorrect and has never been a standard guideline for CPR. Attempting to provide breaths before ensuring a clear airway is illogical and ineffective.
- Option D: This option is incorrect because a correct sequence (Compression-Airway-Breathing) is provided in the options.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Sequence of Cardiopulmonary Resuscitation (CPR) according to AHA guidelines as background academic context rather than a clinical decision trigger.
- Immediate initiation of high-quality chest compressions (correct rate, depth, and full recoil) is the single most important factor in improving survival rates from cardiac arrest. Nurses must be proficient in the C-A-B sequence.
- Minimizing interruptions in chest compressions to less than 10 seconds is crucial. Any pause in compressions causes blood flow to the brain and heart to stop.
- What if? The patient is a newborn immediately after delivery. In this specific population, the cause of arrest is usually respiratory. Therefore, resuscitation guidelines for newborns (NRP - Neonatal Resuscitation Program) often prioritize airway and breathing, following an A-B-C approach.
How to Approach the Question
- First, identify the key part of the question: it asks for the current CPR order according to the American Heart Association (AHA).
- Recall the fundamental principles of Basic Life Support (BLS). Remember that a major guideline change occurred in 2010.
- The change shifted the priority from Airway (A) to Compressions (C) to emphasize the importance of immediate blood circulation.
- Evaluate the options based on this knowledge. The mnemonic C-A-B represents the current sequence: Compression, Airway, Breathing.
- Eliminate the A-B-C option, as it represents the outdated guideline.
- Select the option that correctly matches the C-A-B sequence.
