Defibs can be used on infants from the age of 1 years old. Ensure that 1 pad goes on their front and one on their back, which is a different placement to those required for patients over 8 years old. Please check your defib and user manual for the exact pad placement, as some models of defibs use different pads for adults and children while others have a key or toggle switch to reduce the amount of energy (joules) to make them suitable to use on children.
