The Philips HeartStart OnSite Adult SMART pads come in a cartridge that attach to the HeartStart OnSite AED. The cartridge can be easily snapped into the AED when replacing the pads. The Pull-handle alllows the rescuer to quickly and easily tear open the pads by just pulling down on marked cartridge handle.

Philips Healthcare recommends have a spare adult SMART pad cartridge stored with the Philips HeartStart OnSite AED.

Note: The pad cartridge has a 2-Year shelf life, and need to be replaced if ever used in a rescue.
