Save valuable time in an emergency with pads that can be used on adults, children and infants. SMART Pads II eliminate the expense of having to purchase different pads sets for different patient types. These pre-connected pads are packaged in a semi-rigid pads case for added protection, and are equipped with a HeartStart compatible plug for easy hand-off to Philips ALS defibrillators and to competitive defibrillators with adapters. For patients under 55 pounds (25 kg) or 0-8 years old, use the Infant/Child Key, if available.
