Philips HeartStart FR3 Pediatric Key 989803150031
The Philips HeartStart FR3 Pediatric Key changes a compatible FR3 AED from adult mode to infant/child mode. Once a trained responder inserts the key, the FR3 lowers its therapy level and provides pediatric CPR instructions. Therefore, responders can use the FR3 with children who weigh under 55 lb (25 kg) or are under 8 years old.
Philips part number 989803150031 works only with the HeartStart FR3 AED. This sale includes one FR3 Infant/Child Key unless the product photos show additional items.
Activates FR3 Infant/Child Mode
First, the responder inserts the Pediatric Key into the port on the front of the FR3. Next, the AED announces “Infant/Child Mode.” The FR3 then adjusts its therapy and CPR prompts for an infant or child.
In addition, the screen shows pediatric pad placement. The responder can then follow the FR3 voice and screen instructions throughout the rescue.
For Children Under 55 Pounds or 8 Years Old
Philips directs responders to use the FR3 Infant/Child Key for a suspected cardiac-arrest victim who weighs under 55 lb (25 kg) or is under 8 years old. However, the key should not remain in place when treating an adult.
If the responder does not know the patient’s age or weight, Philips directs the user to operate the FR3 without the Infant/Child Key. Therefore, trained responders should always follow the FR3 instructions, their training, and local rescue protocols.
No Separate Pediatric Pads Required
The FR3 Pediatric Key works with Philips HeartStart SMART Pads III. As a result, responders do not need a separate set of pediatric defibrillation pads for the FR3.
Instead, the same compatible SMART Pads III can serve adult and pediatric patients. However, responders must change pad placement for an infant or child by placing one pad on the chest and one on the back.
This listing does not include SMART Pads III unless the product photos or Simon Medical specifically show them.

Important Use and Storage Information
Do not leave the Pediatric Key inside the FR3 while the AED remains in storage. If the key stays inserted, the FR3 may deliver pediatric therapy during an adult rescue. In addition, the AED may produce alert chirps during a later self-test.
Instead, store the key in the Infant/Child Key area of a compatible FR3 carrying case. Before each use, inspect the key for damage and confirm that the FR3 recognizes it.
Furthermore, trained users should follow the Philips FR3 instructions and local medical protocols. The Pediatric Key should never replace proper AED and infant/child CPR training.

Moreover, Simon Medical includes its standard 90-day warranty with the purchase. After delivery, the receiving facility should test the key with its FR3 AED and confirm proper infant/child mode operation.
