In which scenarios should you perform CPR?

Performing CPR is essential in situations where someone's life is at risk, specifically when they are unresponsive and not breathing or showing signs of abnormal breathing. These signs indicate that the heart has stopped pumping blood effectively, typically resulting in cardiac arrest. During such emergencies, immediate action is crucial because the victim's brain and other vital organs can sustain damage within minutes due to lack of oxygen. CPR helps maintain blood circulation and can significantly increase the chances of survival until professional medical help arrives.

In contrast, scenarios such as someone meditating, experiencing chest pain, or having a cold do not warrant CPR. Meditating individuals are typically conscious and breathing normally, while chest pain could indicate a heart problem, but it does not necessarily mean that CPR is required unless the person becomes unresponsive and stops breathing. Similarly, a cold is not life-threatening and does not involve the critical conditions that necessitate CPR.
