    摘要： In one embodiment, a method is characterized by measuring a patient parameter associated with a human body; in response to the patient parameter, retrieving a maximum expected device parameter; and setting a limit on an energy source such that during defibrillation of the patient a defibrillation parameter associated with the maximum expected device parameter is within a defined tolerance. In another embodiment, a method is characterized by specifying at least one device parameter limit of a defibrillation unit; and in response to the at least one specified device parameter, determining a prediction confidence level at which the device parameter limit is exceeded for one or more values of a patient parameter. In another embodiment, a method is characterized by specifying a prediction confidence level to which a defibrillation unit device parameter is correlated with one or more values of a patient parameter; and in response to the specified prediction confidence level, determining a defibrillation unit device parameter from one or more values of a patient parameter. In other embodiments, circuitry is used to at least partially effect the foregoing-described methods; the circuitry can include and/or utilize virtually any combination of hardware, software, and/or firmware configured to effect the foregoing-described method, depending upon the design choices of the system designer. In other embodiments, signal bearing media at least partially bear the foregoing-described methods.

    摘要： A portable electronic unit, such as a defibrillator, includes an autotest system for automatically self-testing various electrical components within the unit during quiescent periods. The autotest system includes an autotest routine that performs an extensive array of rigorous yet time-consuming tests that are impractical to perform during normal modes of operation of the unit. A real-time clock can be set to initiate the autotest routine at a time when the unit is unlikely to be used for its normal mode of operation. The autotest system provides a strip chart printout of the results of the various self-tests performed on the unit, and provides messages on a visual display of any error conditions. If the autotest system detects a needs service malfunction, the operator must acknowledge the error with an input to the unit before the unit will enter into its normal mode of operation. If the autotest system detects a service mandatory malfunction, the unit will discontinue any normal mode of operation until the malfunction is corrected. The autorest system immediately discontinues the autorest routine upon power-up of the unit by an operator for use of the unit in its normal mode of operation.

    摘要： A medical information system. Data from electrodes are digitized and received by a microprocessor which causes them to be stored in a memory in accordance with a predetermined priority scheme. The data stored in the memory means can be read out to a monitor, a printer, or another computer for further processing.

    摘要： A detector system for sensing the presence, or absence, of electrically-conductive liquid in contact with two probe members. The system includes switchable voltage sources to selectively establish a potential across capacitors connected to the probe members, and detection systems for sensing the magnitudes of charges on the capacitors. The magnitudes of the sampled charge at given intervals is indicative of the presence, or absence, of ionic liquid in contact with the probe members.
