Answer :
Final answer:
CPR should be used on an unresponsive and non-breathing person. It is critical to perform CPR correctly to avoid causing harm, and proper training is highly recommended to ensure effective administration.Hence option D is correct.
Explanation:
When to Use CPR
CPR (cardiopulmonary resuscitation) should only be used on an unresponsive person who is not breathing. In cases of drowning, it is vital to first remove the individual from the water as CPR is ineffective while in the water. Once the person is on stable ground, trained responders perform chest compressions and mouth-to-mouth breathing, while bystanders are encouraged to do compression-only CPR.
It's crucial to initiate CPR as soon as possible since brain damage and death of neurons can occur within minutes of the heart stopping. Moreover, CPR's efficacy is significantly higher if there is no water in the lungs, such as situations where the victim has an airway protected by a laryngeal spasm.
However, CPR must be performed correctly to avoid injuries like broken ribs or damage to the liver due to improper hand placement. This highlights the importance of proper training and certification for performing CPR. Emergency techniques like CPR are critical for maintaining blood flow, especially to the brain, and can be a lifesaver when performed correctly.
Overall, it's essential to remember that CPR should only be administered to individuals who have stopped breathing and have no pulse, and not in situations where it could cause more harm, such as when there is significant bleeding or for a person who is breathing adequately.
