Correct option is C
Sol. According to the AHA 2020 CPR guidelines, the correct sequence is C-A-B (Compression, Airway, Breathing). Chest compressions are started first to maintain blood circulation to the brain and vital organs. This approach improves survival outcomes in cardiac arrest cases and is standard in Basic Life Support (BLS).
Explanation of each option:
· (a) Airway breathing compression – This was part of older A-B-C protocol, now outdated because it delays vital chest compressions.
· (b) Breathing airway compression – Incorrect sequence; prioritizing breathing before chest compressions can reduce survival chances.
· (c) Compression airway breathing – Correct. It starts with chest compressions, which are most critical in the first minutes of cardiac arrest.
· (d) None of these – Incorrect because option (c) accurately reflects current CPR practice.
