Electrode pads are contained in an innovative Pad-Pak™ or Pediatric-Pak™ which are accessible by pulling the green tab. Pads are accessible with the unit in the storage case (supplied with each unit). The Adult (Gray) Pad-Pak™ is for patients >8 years & 55 lbs. The Pediatric-Pak™ (Pink) is for patients 1-8 years & <55 lbs. Either cartridge can be used with the new samaritan PAD (Model 300P). Note: Pediatric-Pak™ cannot be used on earlier models. When electrode pads are applied, the system automatically assesses the patient to determine if a shock is required. If not, the unit will prompt the rescuer to begin CPR Verbal and visual prompts guide the rescuer when to touch and when not to touch the patient. If it is determined that a shock is required, the Shock Button illuminates. A CPR tone and flashing icon coach the rescuer in delivering chest compressions according to AHA or ERC 2005 guidelines- 100 compressions per minute - for 2 minute intervals.
