During CPR, what is the action taken if the patient shows no response?

When a patient shows no response during CPR, the immediate action taken is to begin chest compressions. This is critical because chest compressions help maintain blood flow to vital organs, particularly the brain and heart, in cases of cardiac arrest. Effective chest compressions facilitate perfusion and increase the chances of survival until more advanced medical help arrives.

In the context of CPR, the guidelines emphasize the importance of starting compressions as soon as it is determined that the person is unresponsive and not breathing normally. This swift action can significantly influence patient outcomes, providing essential oxygenation to tissues during a period when the heart is not effectively pumping blood.

While other actions like checking for a pulse or calling for emergency services are also important steps in the overall CPR process, they should not delay the initiation of chest compressions. Calling for emergency services is generally done simultaneously or immediately after confirming the unresponsiveness but does not replace the need for immediate resuscitation efforts. Therefore, starting chest compressions without delay is the correct and necessary response in this lifesaving scenario.
