Laerdal Heartstart FRX Child/Infant Key, Each

The Laerdal Heartstart FRx Child/Infant Key is designed for use with the Heartstart FRx Defibrilator when treating an infant or child who is under 25kg or 8 years old. Once the key is inserted, the defibrilator reduces the defibrilation energy to an appropriate level for children. Graphics on the key show the proper pad placement for infants or children.
