Which sequence is correct for the three-step checks of CPR?

For effective CPR, the correct sequence of the three-step checks is crucial to ensure the victim receives the proper assistance promptly. The sequence of checking circulation, airway, and then breathing allows a responder to prioritize actions in a way that maximizes the chances of survival.

Starting with circulation involves checking for signs of a pulse or any response from the person, as the primary goal is to address the heart's function first in cases of cardiac arrest. If there is no pulse, immediate chest compressions should be initiated to help restore blood flow.

Next, assessing the airway is vital because the airway must be clear to ensure that oxygen can reach the lungs. A blocked airway can prevent effective breathing and contribute further to the victim's condition.

Finally, checking for breathing involves looking for chest rise and fall, listening for breath sounds, and feeling for air on your cheek. It is important to establish whether the individual is breathing adequately and, if not, provide rescue breaths if CPR is being administered.

This systematic approach not only aligns with training guidelines but emphasizes the importance of timely interventions during a critical emergency situation. The other sequences provided do not reflect the established protocols for CPR, which could lead to ineffective administration of care during a life-threatening scenario.
