YMCA Basic Life Support Practice Test 2025 – Complete Exam Prep

The correct answer highlights that while the basic principles of Basic Life Support (BLS) apply to both children and adults, there are essential modifications in depth and force when performing CPR on children. In children, the amount of force used in chest compressions is less than that used for adults, as their bodies are smaller and more fragile. The compression depth is typically around one-third the depth of the child's chest, which is generally about 1.5 to 2 inches.

Additionally, ventilation methods are also adapted for children. For infants, a gentle puff of breath is necessary to avoid over-inflation, which can lead to risks such as barotrauma. Therefore, while the fundamental objective is the same—restoring circulation and breathing—the techniques employed must be adjusted to ensure the safety and effectiveness of the procedure. Understanding these differences is crucial for anyone providing BLS, as correctly applying these modifications can significantly impact the outcome in emergency situations involving children.
