摘要： An electrotherapy apparatus includes a connecting mechanism coupled between an energy source and a pair of electrodes for contacting a patient. A controller coupled to the energy source configures the energy source to provide a selected one of a plurality of energy levels. The controller actuates the connecting mechanism to couple the energy source to the electrodes. A sensor coupled to the controller measures a parameter or parameters related to the energy delivered to the patient through the electrodes. The controller performs an operation using the output received from the sensor. Based upon the operation, the controller actuates the connecting mechanism to decouple the energy source from the electrodes. In an embodiment of the electrotherapy apparatus, the energy source includes a high voltage power supply for charging a capacitor to a selected one of a plurality of initial voltages. The sensor includes a voltage sensor to measure the voltage across the capacitor and a current sensor to measure the current supplied by the capacitor. The connecting mechanism includes electronic switches coupled between the capacitor and the electrodes to permit application of an electrotherapy waveform in either polarity. The controller performs the operation using the measured voltages and currents to control the electronic switches. The operation may include computing the patient impedance, determining a time constant of the voltage or current, determining a quantity of charge delivered to the patient, or determining the time required for the voltage or current to substantially equal a predetermined fraction of the voltage or current.

In these embodiments, the method also may include the step of performing the battery capacity test when the monitored temperature reaches the second temperature if there is no indication of device operational status corresponding to the second temperature stored in memory, the second temperature is lower than a temperature associated with an indication of a non-warning device operational status stored in memory, and the second temperature is higher than a temperature associated with an indication of a warning operational status; and indicating device operational status as a result of the battery capacity test. The method may also include the step of storing in memory an association between the second temperature and device operational status.

摘要： A method and apparatus for indicating a low battery condition and for dynamically controlling the load on a battery in order to optimize battery usage. A dynamic load controller for a battery includes detection circuitry for measuring at least one condition related to battery capacity, and power control circuitry for adjusting a power load on the battery based upon the condition. The dynamic load controller may be employed to control the power load on a battery that powers an electrotherapy device, such as a defibrillator. The battery condition may include the slope of a capacity curve, which may be the product of the battery voltage and the power delivered from the battery as a function of the delivered power. Based upon this condition, the power control circuitry adjusts the power load to optimize power delivery from the battery. The controller includes circuitry for indicating a low battery condition if battery voltage falls below a battery voltage threshold and the power load falls below a power threshold, or if the optimum power falls below a power threshold. The controller also includes circuitry for indicating a replace battery condition if battery voltage falls below a battery voltage threshold and the power load falls below a minimum power threshold, or if the optimum power falls below a minimum power threshold.

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.
摘要翻译：本发明提供一种外部除颤器和除颤方法，其自动补偿用于除颤和心脏复律的电疗脉冲递送中的患者对患者的阻抗差异。在优选实施例中，除颤器具有能够通过患者身上的电极排出的能量源，以提供双相电压或电流脉冲。在本发明的一个方面，第一和第二相位持续时间和初始第一相位振幅是预定值。在本发明的第二方面中，如果脉冲的第一相位的幅度在预定的第一相位持续时间结束时不能下降到阈值，则脉冲的第一相位的持续时间可能会延长与高阻抗患者。在本发明的第三方面中，当第一相位幅度下降到低于阈值时或当第一相位持续时间达到阈值时间值（以先到者为准）时，第一相位结束，如同低平均阻抗患者可能发生的那样。改变输送的双相脉冲的这种方法和装置由此通过改变递送的电疗脉冲的性质来补偿患者的阻抗差异，导致更小，更有效和更便宜的除颤器。
