What is the critical first step during CPR?

The critical first step during CPR is to determine responsiveness. Before any intervention, it is essential to assess whether the person is conscious or unconscious. This step helps to ensure that the situation is assessed correctly and guides the responder on the next course of action. If the individual is unresponsive, it is important to call for help immediately or activate emergency services, ensuring that professional medical assistance is on the way while simultaneously addressing the person's needs.

Following the responsiveness check, the responder can then proceed with chest compressions and rescue breaths if necessary, but these actions follow the initial assessment of the person's state. The focus on assessing responsiveness sets the stage for an effective and organized response to the emergency. Recognizing unresponsiveness is crucial as it signifies the need for immediate action, allowing the responder to provide the appropriate intervention swiftly.
