    摘要: An energy reduction unit is removably connectable to an external defibrillator to reduce the defibrillation energy delivered by the defibrillator to a patient. Use of the energy reduction unit is particularly suited to defibrillating pediatric patients (infants and children under 8) with an automatic or semi-automatic external defibrillator (AED). In one embodiment, the energy reduction unit includes an attenuator which partially dissipates energy produced by the AED. The attenuator is advantageously designed to present an impedance to the AED which, when connected to the patient, is approximately equal to the patient's impedance. The energy reduction unit may include a presence-detect function which enables the defibrillator to modify analysis of ECG signals to account for differences heart rhythms of pediatric and adult patients. In a second embodiment, the energy reduction unit includes an energy control modifier circuit which affects the charging operations performed internal to the AED. Other than being attached to the defibrillation equipment, the energy reduction unit does not otherwise change how an operator uses the equipment.

    摘要: An electrotherapy apparatus, such as a defibrillator, includes a connecting mechanism coupled between an energy source and electrodes. The connecting mechanism allows selective coupling of the energy source to the electrodes. The energy source includes a capacitor and a high voltage power supply for charging the capacitor. The electrotherapy apparatus further includes a waveform measuring device for measuring a patient ECG waveform. The electrotherapy apparatus also includes a controller coupled to the connecting mechanism, the energy source, and the waveform measuring device. The controller actuates the connecting mechanism to deliver a bi-phasic waveform to the patient. In addition, the controller analyzes the ECG waveform to detect when the patient is experiencing either course arrhythmia or fine arrhythmia. The detection of course arrhythmia or fine arrhythmia can be done by comparing the amplitude of the ECG waveform to a predetermined amplitude value, by comparing the power spectrum of the ECG waveform to a predetermined frequency value, by measuring the duration of the arrhythmia, or by measuring some combination of these ECG waveform characteristics. Based upon whether the patient is experiencing course arrhythmia or fine arrhythmia, the controller adjusts the amplitude and/or duration of the bi-phasic waveform applied to the patient to optimize the likelihood of defibrillation.

    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: Electromagnetic signal delivery for tissue affected by neuronal dysfunction, degradation, damage, and/or necrosis, and associated systems and methods are disclosed. A method in accordance with one embodiment of the invention includes identifying an affected region, with the affected region including neuronal tissue that, at least during a pre-dysfunctional period, was in neural communication with neuronal tissue in a dysfunctional region. The affected tissue can be functionally adversely affected by neuronal dysfunction in the dysfunctional region. The method can further include applying electromagnetic signals to the neuronal tissue in the affected region. For example, the electromagnetic signals can be applied to a hypo-active neural region that is not physically damaged, and has been identified as likely to recover at least in part as a result of electromagnetic signals. Signals can be applied at sub-threshold levels to cortical and/or subcortical regions.

    摘要: The following disclosure describes several methods and apparatus for intracranial electrical stimulation to treat or otherwise effectuate a change in neural-functions of a patient. Several embodiments of methods in accordance with the invention are directed toward enhancing or otherwise inducing a lasting change in neural activity to effectuate a particular neural-function. Such lasting change in neural activity is defined as “neuroplasticity.” The methods in accordance with the invention can be used to treat brain damage (e.g., stroke, trauma, etc.), brain disease (e.g., Alzheimer's, Pick's, Parkinson's, etc.), and/or brain disorders (e.g., epilepsy, depression, etc.). The methods in accordance with the invention can also be used to enhance neural-function of normal, healthy brains (e.g., learning, memory, etc.), or to control sensory functions (e.g., pain). Certain embodiments of methods in accordance with the invention electrically stimulate the brain at a stimulation site where neuroplasticity is occurring. The stimulation site may be different than the region in the brain where neural activity is typically present to perform the particular neural function according to the functional organization of the brain. In one embodiment in which neuroplasticity related to the neural-function occurs in the brain, the method can include identifying the location where such neuroplasticity is present. In an alternative embodiment in which neuroplasticity is not occurring in the brain, an alternative aspect is to induce neuroplasticity at a stimulation site where it is expected to occur. Several embodiments of these methods that are expected to produce a lasting effect on the intended neural activity at the stimulation site use electrical pulses that increase the resting membrane potential of neurons at the stimulation site to a subthreshold level.

    摘要: An electrotherapy apparatus performs a low level impedance measurement upon the patient to determine the initial charge level on the capacitor used to deliver an electrotherapy waveform to the patient. In addition, the waveform applied to the patient is dynamically controlled to compensate for patient impedance variability. Determining the initial charge level in this manner prevents unnecessarily high peak currents from flowing in low impedance patients while maintaining peak current in high impedance patients at therapeutically beneficial levels. The electrotherapy apparatus includes a measuring device used for measuring a parameter related to the impedance of the patient. The parameter is used for determining low level patient impedance. The measuring device provides a voltage output used by a controller for determining the initial charge level of the capacitor. A first embodiment of a first electrotherapy apparatus includes four electronic switches to deliver a bi-phasic waveform to the patient. The first embodiment of the first electrotherapy apparatus further includes a comparator coupled to a timer to monitor the voltage across the capacitor and control the termination or extension of the waveform applied to the patient. A first embodiment of a second electrotherapy apparatus measures the charge delivered to the patient and sets the time of the first phase of the bi-phasic pulse based upon the time required to deliver a predetermined amount of charge to the patient.
