The electrode section and the CPR administration section are positioned in the defibrillation electrode pad relative to each other such that the CPR administration section is located above a sternum of an adult subject and the electrode section is located in a position appropriate for the administration of a defibrillation shock to the adult subject when the defibrillation electrode pad is oriented in a first orientation and such that the CPR administration section is located above a sternum of a pediatric subject and the electrode section is located in a position appropriate for the administration of a defibrillation shock to the pediatric subject when the defibrillation electrode pad is oriented in a second orientation different from the first orientation.

A chest compression device for cardiopulmonary resuscitation comprises a support structure 2 for placement about a patient's chest and for holding a chest compressor 6 above a patient's sternum; a chest compressor 6 mounted on the support structure 2; and lateral chest supports 14 attached to the support structure 2 at points laterally either side of the chest when the device is in use, such that the lateral chest supports 14 will apply lateral pressure to the sides of the chest synchronized with a chest compression by the chest compressor 6.

An automated chest compression (CC) system is described that includes a chest compressor configured to administer chest compressions to a patient, at least one tilt adjuster configured to tilt at least the head of the patient to a tilt angle during the administration of chest compressions to the patient, a patient support structure configured to couple to the chest compressor and to the at least one tilt adjuster, one or more tilt sensors, and a CC device controller configured to control the chest compressor to administer the chest compressions at a resuscitative rate, receive one or more signals, from the one or more tilt sensors, indicative of the tilt angle, determine tilt angle information from the one or more signals indicative of the tilt angle, and provide the tilt angle information to a user interface, wherein the patient support structure is adapted to support the back of the patient.

A resuscitation system that includes at least two defibrillation electrodes configured to be applied to the exterior of the chest of a patient for delivering a defibrillation shock, a source of one or more ECG signals from the patient, a defibrillation circuit for delivering a defibrillation shock to the defibrillation electrodes, a control box that receives and processes the ECG signals to determine whether a defibrillation shock should be delivered or whether CPR should be performed, and that issues instructions to the user either to deliver a defibrillation shock or to perform CPR, wherein the determination of whether CPR should be performed and the instructions to perform CPR can occur at substantially any point during a rescue.

Methods and devices for chest compression depth measurement for CPR.

An electrode assembly includes a first surface to be placed adjacent a person's skin and a second surface including a plurality of reservoirs of conductive gel. The plurality of reservoirs of conductive gel are disposed on sections of the electrode assembly that are at least partially physically separated and may move at least partially independently of one another to conform to contours of a body of a patient. The electrode assembly is configured to dispense an amount of the electrically conductive gel onto the first surface in response to an activation signal and to provide for a defibrillating shock to be applied to the patient through the amount of the electrically conductive gel.

Chest compression machine systems and methods adjust the administration of patient treatment based on received physiological parameter measurements, such as a CO.sub.2 measurement. Adjustment of the administered chest compressions can include adjusting one or more chest compression parameters, such as the depth of the administered compressions, the administration of active decompressions, adjusting the height of active decompression, adjusting the rate of compressions and/or active decompressions and/or other changes to one or more properties, or characteristics, of the administered chest compressions and/or active decompressions.

A system for assisting a rescuer in providing resuscitative treatment to a victim is described. The system includes a motion sensor configured to generate motion sensor signals that are indicative of motion of the chest of the victim during chest compressions, an input device configured to receive user input indicative of a type of chest compressions, an output device, and a processor, a memory, and associated circuitry, the processor communicatively coupled to the motion sensor, the input device, and the output device and is configured to receive the motion sensor signals and the user input indicative of the type of chest compressions, determine chest compression feedback for the rescuer based on the motion sensor signals, and control the output device to selectively provide the chest compression feedback for the rescuer based at least in part on the type of chest compressions indicated by the user input.

A device for assisting a caregiver in delivering cardiac resuscitation to a patient, the device comprising a user interface configured to deliver prompts to a caregiver to assist the caregiver in delivering cardiac resuscitation to a patient; at least one sensor configured to detect the caregiver's progress in delivering the cardiac resuscitation, wherein the sensor is configured to provide a signal containing information indicative of ventilation; a memory in which a plurality of different prompts are stored, including at least one ventilation progress prompt to guide the rescuer's performance of ventilation; a processor configured to process the output of the sensor to determine a parameter descriptive of ventilation progress and to determine whether the ventilation progress prompt should be selected for delivery. Possible parameters descriptive of ventilation progress include ventilation rate, delivered tidal volume, and flow rate.
