Final answer:
When performing CPR, stop to check for signs of life if you notice obvious signs or can't physically continue. Continue until help arrives or the person recovers. Proper technique and training are critical for effective CPR.
Step-by-step explanation:
When you begin CPR on victims of all ages, you should only stop to check for signs of life if you notice obvious signs of life, when an AED becomes available, or when you are physically unable to continue due to exhaustion, or if the scene becomes unsafe. Rescuers should perform CPR until the person regains spontaneous contractions or is declared dead by an experienced healthcare professional. Remember, timely and effective delivery of CPR can make a critical difference in survival and recovery.
It is vital to administer CPR promptly and effectively after ensuring the victim is on a stable surface, out of water if drowning, and the airway is clear. CPR, especially if commenced within minutes of cardiac arrest, can maintain blood flow to vital organs, particularly the brain. High-quality CPR compressions are essential, with proper hand placement on the sternum advised between T4 and T9 vertebrae to avoid injuries like broken ribs or damage to internal organs.
Proper CPR training is crucial for rescuers to prevent additional harm to the patient and to provide the best chance of recovery. Such training includes practicing the compression technique on a mannequin and is offered by various organizations, including the American Red Cross.
