The correct answer is:d. When chest pressure is applied, the strength is pulled from the shoulder and back muscles without bending the arms.External heart massage, also known as chest compressions, is a technique used in cardiopulmonary resuscitation (CPR) to help maintain circulation in cases of cardiac arrest. Here are some key points to understand about the technique:1. **Location**: Chest compressions are applied to the center of the chest, specifically on the lower half of the sternum (breastbone). This ensures effective compression of the heart and subsequent circulation.2. **Positioning**: The rescuer should position themselves directly above the victim's chest. It is important to keep the arms straight and elbows locked to ensure effective compressions.3. **Depth and Rate**: The recommended depth for chest compressions in adults is about 2 inches (5 cm), and the rate should be at least 100-120 compressions per minute. The compressions should be deep enough to depress the thoracic cage but not so deep that they cause the chest to collapse.4. **Body Mechanics**: The rescuer should use their body weight to apply force, pulling the arms straight back and down to compress the chest. This technique engages the shoulder and back muscles, reducing the risk of arm fatigue and ensuring effective compressions.5. **Avoid Bending the Arms**: Bending the arms at the elbows can reduce the effectiveness of the compressions and increase the risk of injury to both the rescuer and the victim.6. **Hand Placement**: Typically, two hands are used for compressions in adults, but if a single hand is all that is available, it should be used to achieve the necessary depth and force.By following these guidelines, chest compressions can be performed effectively to help maintain circulation and support the victim's chances of survival.
