    摘要： An external defibrillator used to treat a patient wirelessly communicates with an implantable medical device (IMD) implanted in the patient. In some embodiments, a telemetry head may be removably coupled to the external defibrillator to facilitate communication with the IMD. The defibrillator may receive information, such as patient, device, physiological, and treatment information, from the IMD. The defibrillator may use some or all of this information during treatment of the patient. For example, the defibrillator may prompt a user, or modify programmed user prompts based on the information. The defibrillator may deliver therapy based on the information. The information may include real-time values of physiological parameters monitored by the IMD, which may be displayed by the external defibrillator. The external defibrillator may control delivery of therapy by the IMD. The defibrillator may collect medical event information during treatment of the patient, and store the medical event information in the IMD.

    摘要： When a defibrillator selects a dosage of energy or current to be delivered to a patient, the defibrillator selects an excitation current frequency and applies the excitation current at the selected frequency to the patient. The frequency of the excitation current is selected as a function of the dosage to be delivered. The patient's response to the excitation current at the selected frequency will accurately reflect the impedance that the defibrillator will “see” when delivering the selected dosage of energy or current.

    摘要： Methods and apparatus are provided for determining a defibrillation treatment protocol in an external defibrillator using a measurement of elapsed time. The present invention provides a defibrillator with a timer function. Upon activation of the defibrillator, an internal timer begins to run. By closely associating the activation of the defibrillator with the onset of the patient's attack, and by making allowances for inherent time differences between these events, the timer provides a measure of the elapsed time between the onset of the patient's emergency and the presentation of the defibrillator at the patient's side. Using this measure of elapsed time, the defibrillator determines an appropriate treatment therapy, such as CPR or defibrillation therapy.

    摘要： A system is disclosed wherein patient data, such as an electrocardiogram (“ECG”) signal or a chest impedance measurement signal, collected by a defibrillator device during a resuscitation event is analyzed and processed by a computing device to provide an assessment of CPR administered during the event. The CPR assessment results in one or more CPR figures of merit that relate to temporal characteristics of the CPR relative to the duration of the event. In one embodiment, the CPR figure of merit represents a percentage of the event period during which chest compressions were administered to the patient.

    摘要： An apparatus and method is provided for a defibrillator that specifies treatment protocols in terms of number of chest compressions instead of time intervals. The defibrillator includes a connection port that is configured to attach with a plurality of electrodes that are capable of delivery of a defibrillation shock and/or sensing one or more physical parameters. An energy storage device capable of storing a charge is attached to the plurality of electrodes. A controller is coupled to the plurality of electrodes and the energy storage device, the controller is configured to provide CPR chest compression instructions in terms of the numbers of CPR chest compressions.

    摘要： Embodiments of the invention include a system and methods for providing status information about resuscitation efforts of a person receiving chest compressions as part of Cardiopulmonary Resuscitation (CPR). A microphone generates a soundtrack by sampling sounds within or around the body of the person receiving CPR. The soundtrack is gated in one or more various ways to eliminate portions of the soundtrack, and analysis performed on the remaining portions. By evaluating the remaining portions of the soundtrack, the system can determine a cardiovascular effect of the compressions and provide status information to the rescuer about the determined cardiovascular effect.
