Final answer:
The correct sequence for basic life support is Compressions, Airway, Breathing, emphasizing the importance of chest compressions to maintain blood circulation during CPR.
Step-by-step explanation:
The correct sequence for basic life support (BLS) according to current guidelines is Compressions, Airway, Breathing. This approach emphasizes the importance of chest compressions to maintain circulation of blood to vital organs, especially the brain. With the heart located between the vertebrae and sternum, applying pressure on the sternum during CPR can manually compress the heart to push blood through the circulatory system. Proper training is crucial for effective CPR, as incorrect technique can cause severe injury. Practice and certification in CPR are widely available, including through the American Red Cross and hospitals.
