What should be done immediately after identifying a patient in cardiac arrest?

Beginning CPR immediately after identifying a patient in cardiac arrest is crucial because it provides essential circulatory support to the brain and other vital organs. In cardiac arrest, the heart is not effectively pumping blood, which can lead to irreversible damage within minutes. High-quality CPR can maintain blood flow and increase the chances of survival until more advanced medical help arrives.

The focus on immediate action aligns with the guidelines for resuscitation, which emphasize that survival chances decrease significantly with each passing minute without effective chest compressions. By starting CPR right away, the provider takes the most critical step in the chain of survival, supporting the patient's chances of recovery.

Other actions, such as calling for help, applying an AED, or checking for a medical bracelet, are important but should follow the commencement of CPR to maximize the patient’s survival chances. Delaying CPR to perform these actions can waste valuable time that could be used to maintain critical blood circulation until emergency services can intervene.
