What is the first response for a child or infant during CPR?

The first response for a child or infant during CPR involves providing initial rescue breaths before administering chest compressions. The correct practice is to give 5 initial rescue breaths to establish an open airway and provide oxygen to the child or infant, who is at a higher risk of cardiac arrest due to respiratory issues. This focus on early rescue breaths helps to ensure that the critical factor of oxygenation is addressed before the heart's rhythmic function is assessed and supported through compressions. Following these breaths, chest compressions are then performed in a rhythm of 30 compressions followed by further rescue breaths. This sequence is particularly vital for children and infants, as they are more likely to need assistance due to respiratory problems rather than cardiac issues, making the initial breaths critical in these situations.
