Verified step by step guidance

1. Understand the purpose of CPR (Cardiopulmonary Resuscitation): CPR is a life-saving technique used to maintain blood circulation and oxygen delivery to vital organs when a person is unresponsive and not breathing normally.
2. Evaluate the conditions listed in the problem: A minor cut on the hand, mild chest pain while conscious, and a mild cough do not indicate the need for CPR. These conditions do not involve unresponsiveness or abnormal breathing.
3. Recognize the critical signs that require CPR: CPR should be initiated when a person is unresponsive and not breathing normally. This is because the heart may have stopped or is not effectively pumping blood, leading to a lack of oxygen in the body.
4. Learn the steps to confirm unresponsiveness and abnormal breathing: Check if the person responds to verbal or physical stimuli (e.g., tapping their shoulder and asking loudly, 'Are you okay?'). Observe their chest for breathing movements and listen for breath sounds.
5. Understand the importance of immediate action: If the person is unresponsive and not breathing normally, begin CPR immediately to increase their chances of survival until professional medical help arrives.
