What is the depth of compressions for children during CPR?

The depth of compressions for children during CPR is indeed 2 inches. This depth is crucial for providing effective blood circulation during cardiac arrest. The rationale behind targeting this specific depth is based on the physiological differences in a child's body compared to adults. Compressions of this depth ensure that sufficient pressure is applied to the chest, which is necessary to compress the heart and facilitate blood flow to vital organs.

In practice, achieving a depth of 2 inches allows the rescuer to utilize their body weight effectively, thereby maximizing the force applied during each compression. It's also important to note that compressions should be delivered at a rate of 100 to 120 compressions per minute, which further emphasizes the balance between depth and speed for optimal resuscitation outcomes.

The guideline of 2 inches is part of a broader set of recommendations that aim to standardize practices in CPR across different age groups, ensuring that rescues are effective and based on current evidence in emergency medical care.
