摘要： The presence of a cardiac pulse in a patient is determined by evaluating physiological signals in the patient. In one embodiment, a medical device evaluates two or more different physiological signals, such as phonocardiogram (PCG) signals, electrocardiogram (ECG) signals, patient impedance signals, piezoelectric signals, and accelerometer signals for features indicative of the presence of a cardiac pulse. Using these features, the medical device determines whether a cardiac pulse is present in the patient. The medical device may also be configured to report whether the patient is in a VF, VT, asystole, or PEA condition, in addition to being in a pulseless condition, and prompt different therapies, such as chest compressions, rescue breathing, defibrillation, and PEA-specific electrotherapy, depending on the analysis of the physiological signals. Auto-capture of a cardiac pulse using pacing stimuli is further provided.

摘要： The presence of a cardiac pulse in a patient is determined by evaluating fluctuations in an electrical signal that represents a measurement of the patient's transthoracic impedance. Impedance signal data obtained from the patient is analyzed for a feature indicative of the presence of a cardiac pulse. Whether a cardiac pulse is present in the patient is determined based on the feature in the impedance signal data. Electrocardiogram (ECG) data may also be obtained in time coordination with the impedance signal data. Various applications for the pulse detection of the invention include detection of PEA and prompting PEA-specific therapy, prompting defibrillation therapy and/or CPR, and prompting rescue breathing depending on detection of respiration.

摘要： Signal data obtained from a piezoelectric sensor placed on a patient's body is used to detect the presence of a cardiac pulse. The piezoelectric sensor has a transducing element adapted to sense movement due to a cardiac pulse and produce piezoelectric signal data in response thereto. Processing circuitry analyzes the piezoelectric signal data for a feature indicative of a cardiac pulse and determines whether a cardiac pulse is present in the patient based on the feature. In one aspect, the feature may be a temporal feature such as a relative change in energy. In another aspect, the feature may be a spectral feature such as the energy or frequency of a peak in the energy spectrum of the signal. In yet another aspect, the feature may be obtained by comparing the piezoelectric signal data with a previously-identified pattern known to predict the presence of a cardiac pulse. Multiple features may also be obtained from the piezoelectric signal data and classified to determine the presence of a cardiac pulse.

摘要： An automated external defibrillator automatically determines the type of patient to which it is attached based on patient-specific information entered by the user. The defibrillator includes electrodes that are adapted for placement on a patient, a pulse generator connected to the electrodes, and processing circuitry that controls the defibrillation pulse delivery from the pulse generator. The automated external defibrillator causes a defibrillation pulse to be delivered to the patient in accordance with the determined patient type. A user interface having a user input connected to the processing circuitry enables the user of the defibrillator to enter patient-specific information. The user may enter the patient-specific information by interacting with the user input during a time period in relation to a prompt from the defibrillator. In another aspect, data pertaining to identification of the type of patient connected to the electrodes may be recorded with event data in a memory.

摘要： A medical device capable of analyzing a patient's ECG, such as an external defibrillator, may be operated according to a method including the steps of: (a) determining if the patient is undergoing motion; (b) if it is determined that the patient is undergoing motion, providing an indication of patient motion; (c) after providing the indication, determining if the patient is undergoing motion, and if the patient is undergoing motion, starting ECG analysis after an elapsed time T0. The elapsed time T0 may be measured from a point in time prior to the commencement of step (a). The method may further include the steps of collecting ECG data of the patient, and initiating analysis of the ECG data prior to step (b). The step (b) may further include the step of interrupting the prior initiated ECG analysis. The method may further include the step of starting a timer when the ECG analysis is commenced, to measure elapsed time.
