What should you do after giving rescue breaths if there is no chest movement?

After giving rescue breaths and observing no chest movement, the correct action is to begin CPR. This step is crucial because the lack of chest movement indicates that the breaths were not effective in delivering oxygen to the lungs and that the person may be in cardiac arrest. By starting CPR, you not only provide artificial ventilation but also maintain blood circulation through chest compressions, which is essential for sustaining life until emergency services can take over.

Beginning CPR follows the basic principles of emergency response. The goal is to keep blood flowing to vital organs, especially the brain and heart. By performing chest compressions in conjunction with rescue breaths, you can help restore some level of oxygenation and circulation, potentially increasing the chances of survival.

The other options are important aspects of care, but in the scenario of no chest movement after rescue breaths, initiating CPR is the most immediate and critical action to take. It is imperative to act quickly, as every second counts in a cardiac emergency situation.
