What is the indication for a provider to begin CPR immediately?

The indication for a provider to begin CPR immediately is when cardiac arrest has been identified. Cardiac arrest occurs when the heart stops beating effectively, leading to a cessation of blood flow to the brain and other vital organs. In this situation, rapid intervention is crucial because brain death can occur within minutes without adequate blood supply.

Recognizing cardiac arrest typically involves checking for unresponsiveness and the absence of normal breathing or pulse. Once confirmed, initiating CPR can help maintain some blood flow to the heart and brain until emergency services arrive and advanced care can be provided.

In contrast, showing signs of distress, being responsive with a weak pulse, or merely arriving at the scene does not warrant the immediate start of CPR, as these situations may not indicate that the heart has stopped functioning altogether. Immediate response during cardiac arrest can significantly improve survival chances, making it critical for the provider to act swiftly upon identifying this condition.
