Step-by-step explanation:
The recommended depth of chest compressions for a child victim is at least 5 cm deep. This means that when performing CPR on a child, you should compress their chest to a depth of at least 5 centimeters. The compressions should be performed at a rate of 100 compressions per minute, which is equivalent to the beat in the song 'Staying Alive' by the Bee Gees.
