Final answer:
Proper hand placement for chest compressions during CPR is on the center of the sternum between the nipples, using the heel of one hand and the other on top of the first, compressing at least 5 cm deep with a rate of 100 compressions per minute.
Step-by-step explanation:
When performing chest compressions on an adult victim during CPR (cardiopulmonary resuscitation), it is crucial to position your hands correctly to ensure effectiveness and to minimize the risk of injury to the person receiving CPR. Place the heel of one hand on the center of the patient's chest, on the sternum, between the nipples. Put the heel of your other hand on top of the first hand, interlocking your fingers. You should then compress the chest at least 5 cm deep and at a rate of 100 compressions per minute, which correlates with the beat of the song 'Staying Alive' by the Bee Gees. Positioning your hands between the lines at T4 and T9 on the victim's sternum is essential to avoid damaging internal organs such as the liver.
It is critical to have proper training in CPR to perform the technique safely and effectively. Without appropriate training, the application of CPR can lead to serious injuries such as broken ribs or sternum. It is possible to practice the compression technique on a mannequin during CPR certification courses offered by various organizations.
