Abstract

A device for assisting a rescuer in delivering therapy to an adult or pediatric patient, the device including a user interface comprising a display and/or audio speakers, the user interface being configured to deliver prompts to a rescuer to assist the rescuer in delivering therapy to a patient; a processor configured to provide prompts to the user interface and to perform an ECG analysis algorithm on ECG information detected from the patient; at least one detection element configured to determine without rescuer input via the user interface that a pediatric patient is being treated; wherein, if a pediatric patient is detected, the processor modifies the ECG analysis algorithm or the prompts provided to the user interface to use an ECG analysis algorithm or prompts adapted for a pediatric patient rather than for an adult patient.

Claims

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;

a processor 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 one or both of the defibrillation electrodes, the sensors being configured to determine a distance between the electrodes after they are placed on the patient'"'"'s chest;

wherein the processor can determine information pertaining to the size of the patient from the distance determined from the one or more sensors, and

wherein the processor can 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.

2. The device of claim 1 wherein the processor estimates the circumferential girth of the patient from the information obtained from the sensors.

3. The device of claim 1 wherein the processor estimates the age of the patient from the information obtained from the sensors.
