Verified step by step guidance

Step 1: Understand the purpose of chest compressions during CPR. Chest compressions are performed to manually pump blood through the heart to maintain circulation to vital organs when the heart has stopped beating effectively.

Step 2: Recognize the anatomical differences between adults and small children. Adults have larger and more rigid chest structures, while small children have smaller and more flexible chest walls. This affects the depth of compressions required.

Step 3: Learn the recommended depth of compressions for adults versus small children. For adults, compressions should be about 2 inches (5 cm) deep, while for small children, the depth is reduced to about 1.5 inches (4 cm) to avoid injury to their smaller and more delicate chest structures.

Step 4: Understand the technique used for compressions. For adults, compressions are typically performed using two hands placed on the center of the chest (lower half of the sternum). For small children, compressions may be performed using one hand, depending on the size of the child and the rescuer's strength.

Step 5: Note that the rate of compressions is the same for adults and small children, typically 100-120 compressions per minute. The location of compressions (center of the chest) is also consistent across age groups, but the depth and technique differ based on the individual's size and anatomy.
