Claim:
1. An external defibrillation device for assisting a rescuer in delivering defibrillation therapy to an adult or pediatric patient, the device comprising a user interface comprising a display or audio speakers, the user interface being configured to deliver prompts to a rescuer to assist the rescuer in delivering therapy to a patient; processing circuitry configured to provide prompts to the user interface and to perform an ECG analysis algorithm on ECG information detected from the patient; defibrillation electrodes for placement on the chest of the patient; one or more sensors located in and/or supported by one or both of the defibrillation electrodes, the sensors and processing circuitry being configured to use at least one output from one of the sensors to determine a distance between the electrodes after they are placed on the patient's chest; wherein the processing circuitry is configured to determine information pertaining to the size of the patient from the distance determined from the output of one or more sensors, and wherein the processing circuitry is configured to vary the prompts, or the ECG analysis algorithm, or the energy delivered to the patient based on the information pertaining to the size of the patient.
