What is the recommended compression depth for a child's and an infant's chest in CPR?

The recommended compression depth for performing CPR on children is approximately one-third the depth of the chest. This is essential to ensure that enough pressure is generated to circulate blood effectively during cardiac arrest. For infants, the guideline also holds that compressions should be about one-third the depth of their chest, which equates to around 1.5 inches. The emphasis on this specific depth is grounded in research showing that effective compressions at this range significantly enhance the chances of survival and increase the likelihood of achieving a return of spontaneous circulation. By adhering to these guidelines, rescuers can provide optimal compressions that meet the physiological needs of a child’s or an infant’s smaller and less rigid chest structure during CPR.
