摘要： A defibrillation system for patients of all ages may include an Automated External Defibrillator (AED) coupled to a set of universal electrodes. Universal electrodes may be reduced-size versions of adult electrodes, and may include an opening to lower effective impedance. The AED may include an adult/pediatric mode control or switch. Based upon the setting of the adult/pediatric switch, the AED may perform an adult defibrillation sequence or a pediatric defibrillation sequence. An adult defibrillation sequence may comprise delivery of one or more waveforms or shocks characterized by energies appropriate for adults, for example, 150 Joule biphasic waveforms. A pediatric defibrillation sequence may comprise delivery of one or more waveforms characterized by energies appropriate for children, for example, 50 Joule biphasic waveforms. Another pediatric defibrillation sequence may comprise delivery of an escalating low-energy shock sequence to a patient, such as a 25 to 50 Joule shock, followed by a 65 to 75 Joule shock as necessary, followed by one or more 100 Joule shocks as necessary.

摘要： A defibrillator capable of delivering a damped biphasic truncated (DBT) defibrillation pulse is provided. An energy storage circuit is coupled across a high voltage switch such as an H-bridge for delivering a defibrillation pulse to the patient through a pair of electrodes. A controller operates to control the entire defibrillation process and detects shockable rhythms from the patient via an ECG front end. The energy storage circuit consists of an energy storage capacitor, a series inductor, a shunt diode, and optionally a resistor in series with the inductor. The controller measures as the patient dependent parameter the time interval between the initial delivery of the defibrillation pulse and the occurrence of the peak current or voltage to determine the first and second phases of the defibrillation pulse to provide for compensation for patient impedance. Other types of patient dependent parameters, measured either before or during delivery of the DBT defibrillation pulse, could be alternatively employed to achieve the impedance compensation.

摘要： This invention provides an external defibrillator and defibrillation method that automatically compensates for patient-to-patient impedance differences in the delivery of electrotherapeutic pulses for defibrillation and cardioversion. In a preferred embodiment, the defibrillator has an energy source that may be discharged through electrodes on the patient to provide a biphasic voltage or current pulse. In one aspect of the invention, the first and second phase duration and initial first phase amplitude are predetermined values. In a second aspect of the invention, the duration of the first phase of the pulse may be extended if the amplitude of the first phase of the pulse fails to fall to a threshold value by the end of the predetermined first phase duration, as might occur with a high impedance patient. In a third aspect of the invention, the first phase ends when the first phase amplitude drops below a threshold value or when the first phase duration reaches a threshold time value, whichever comes first, as might occur with a low to average impedance patient. This method and apparatus of altering the delivered biphasic pulse thereby compensates for patient impedance differences by changing the nature of the delivered electrotherapeutic pulse, resulting in a smaller, more efficient and less expensive defibrillator.

摘要： The present invention is an apparatus and method for detecting differential mode signals in an environment where differential mode signals co-exist, and might be corrupted by, common mode signals. The most basic apparatus of the present invention essentially comprises first and second input leads through which both differential mode and common mode signals are input; a first amplifier block having a gain that is substantially one; and at least an inverting node and a non-inverting node connected to the first and second input leads. The output of the amplifier block is fed back to the input of the non-inverting node of the amplifier block in a manner to increase differential mode impedance while maintaining a low common mode impedance. Various embodiments of the basic presently claimed circuitry provides for additional methods of monitoring the level of common-mode signal introduced to the apparatus and other fault detection functions.

摘要： A defibrillator is described which executes a resuscitation protocol having a CPR pause period. The CPR pause period may be interrupted for the acquisition of ECG signal data which is not contaminated by chest compression artifacts. Following the acquisition of ECG signal data, the CPR period resumes and continues for its full period. The ECG signal data acquired during the interruption of the CPR period is analyzed and, if a shockable rhythm is identified, a shock sequence is initiated immediately upon conclusion of the CPR period.

摘要： A defibrillator having an energy storage capacitor network with multiple configurations selected according to patient impedance and desired energy level for delivery of an impedance-compensated defibrillation pulse is provided. The set of configurations may include series, parallel, and series/parallel combinations of energy storage capacitors within the energy storage capacitor network. The impedance-compensated defibrillation pulse may be delivered over an expanded range of energy levels while limiting the peak current to levels that are safe for the patient using configurations tailored for lower impedance patients and limiting the range of defibrillation pulse durations and providing adequate current levels for higher impedance patients. Configurations of the energy storage capacitor network may be readily added to extend the range of energy levels well above 200 joules.

摘要： An apparatus analyzes a composite input signal to determine whether the amount of common mode signal in the composite signal is unacceptably high; thus, precluding an accurate diagnosis of the differential mode signal of interest. Method steps include separating the composite signal input into intermediate signals that are known functions of the differential mode signals of interest and common mode signals (or a suitable combination thereof). In one embodiment, the intermediate signals are cross-correlated to produce a measure of correlation between the intermediate signals. This measure is then compared with a threshold value. If the comparison is favorable, then the data is presumed to be uncorrupted and analysis of the signal representing the differential mode signal continues. Otherwise, the data is presumed to be corrupted and analysis of the signal data is inhibited. In another embodiment, the intermediate signal representing the common mode signal is itself compared against a threshold value without first cross-correlating with the intermediate signal that represents the differential mode signal. If the comparison is favorable, then it may be concluded that the potential for corruption is small and analysis of the intermediate or composite signal is continued.
