How long should you continue CPR before calling for additional help?

The correct answer is that you should continue CPR until the person shows signs of life. This is essential because the purpose of CPR is to maintain blood flow and oxygenation to vital organs, particularly the heart and brain, until professional help arrives or the person begins to show indications of recovery. Signs of life can include movement, coughing, or the ability to breathe on their own.

Continuing CPR until signs of life are present is crucial, as every moment counts in a cardiac emergency. If someone demonstrates signs of life, it indicates that they are starting to regain consciousness and that their heart may be functioning again, which allows you to stop CPR and monitor them until help arrives.

Other potential intervals for CPR, such as continuing for a specific time frame like 1 or 5 minutes, are not recommended since every situation is unique. Focusing solely on a time limit may lead to unnecessary interruptions in the life-saving process. Likewise, relying on another person to take over without being certain that they are available or ready could lead to critical moments without adequate care for the person experiencing the emergency. Thus, remaining engaged in CPR until signs of life become evident is the most appropriate and effective approach.
