In the event of cardiac arrest, when should compressions be started?

Starting compressions as soon as possible is critical in the event of cardiac arrest. The American Heart Association (AHA) guidelines emphasize that chest compressions should begin within 10 seconds of recognizing that a patient is in cardiac arrest. This prompt action maximizes the chances of survival, as it helps maintain blood flow to vital organs until more advanced medical care can be provided.

The first few moments after cardiac arrest are crucial, and initiating compressions quickly can make a significant difference in the patient's outcome. Recognizing that the patient is unresponsive and not breathing normally should trigger immediate action, which includes starting CPR without delay.

Other options might suggest waiting for certain conditions or events, such as establishing a pulse check or waiting for emergency services to be called, which could lead to critical delays in lifesaving efforts. The essence of effective CPR is to act swiftly and decisively, focusing on compressions as the key lifesaving maneuver in these urgent situations.
