What is the correct sequence of steps in CPR?

In the context of CPR (Cardiopulmonary Resuscitation), the correct sequence of steps is fundamentally important for effectively reviving a person in cardiac arrest. The standard approach recommended by organizations such as the American Heart Association emphasizes that chest compressions should be initiated first, followed by the establishment of an airway and then providing rescue breaths. This sequence ensures that blood circulation is prioritized to maintain critical organ function.

The step involving chest compressions is crucial as it helps to circulate oxygenated blood to the brain and other vital organs. Promptly delivering chest compressions increases the chances of survival and improves outcomes significantly. After initiating compressions, the airway needs to be opened to ensure that oxygen can reach the lungs, followed by giving breaths if trained and if needed.

In this context, option D accurately identifies the required sequence: chest compressions to start, followed by addressing the airway, and then administering breaths. This aligns with the guidelines for effective CPR and underscores the importance of each step in the revival process.
