What should you do if a victim shows no signs of breathing?

When a victim shows no signs of breathing, it is critical to act promptly, as this indicates a life-threatening situation. Starting CPR immediately is crucial because it can help maintain blood flow to vital organs such as the brain and heart. CPR involves chest compressions and rescue breaths, which can help keep the victim alive until emergency medical services arrive or until the victim begins to breathe on their own.

In cases where there is no breathing, other actions such as attempting to wake the victim, merely calling for help without taking further action, or waiting for natural breathing to resume are ineffective and could lead to severe consequences, including death. Without immediate intervention like CPR, the lack of oxygen will cause permanent damage to the body's organs within minutes. Therefore, initiating CPR is the most appropriate and life-saving response in this scenario.
