Final answer:
During CPR compressions, place your hands on the sternum between T4 and T9. Ensure proper depth and rate of compressions, and seek proper training to avoid injury.
Step-by-step explanation:
The main answer to where you should put your hands during CPR compressions is on the sternum, specifically in the area between the thoracic vertebrae T4 and T9. Position your hands in the center of the chest, with the heel of one hand on the sternum and the other hand on top, interlocking your fingers. It is critical to avoid placing your hands too low as it can drive the xiphoid process into the liver, potentially causing fatal damage. CPR compressions should be at least 5 cm deep and at a rate of 100 compressions per minute, which correlates to the beat of the song "Staying Alive".
It should be noted that while CPR is a crucial life-saving technique, it can cause injuries such as broken ribs or sternum if performed incorrectly. Therefore, proper training and certification in CPR is strongly recommended for both medical personnel and the general public.
