Abstract: 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.

Abstract: The fuel system of a dual fuel turbine includes a flow control valve having a metering purge valve that in one state directly meters fuel to injectors of the turbine, in another state closes of fuel flow and passes purge air to the injectors and in another state positively closes of flow of both fuel and purge air. The metering purge valve is a pressure compensated spool valve that has a unique cross-ported interchange that passes fuel from the inlet through the spool to the metering edge. The direct metering of the valve to the injectors eliminates the need for additional shut off valves, and if used with a combining valve having an integral distributor section metering fuel to multiple injectors, the need for a separate flow divider is also eliminated. The valve can be actively cooled by dedicated coolant lines or lines shared with other flow control components such as additional metering valves for either the primary or secondary fuel.

Abstract: A system is disclosed wherein patient data, such as an electrocardiogram (“ECG”) signal or a chest impedance measurement signal, collected by a defibrillator device during a resuscitation event is analyzed and processed by a computing device to provide an assessment of CPR administered during the event. The CPR assessment results in one or more CPR figures of merit that relate to temporal characteristics of the CPR relative to the duration of the event. In one embodiment, the CPR figure of merit represents a percentage of the event period during which chest compressions were administered to the patient.

Abstract: A venting probe insertion chamber that is attached to a uniquely designed port which combines the attributes of a probe insertion chamber along with the ability to vent to atmosphere gasses that are present in piping system. This invention combines the functions of two existing products in an economically viable product. This inventive design performs all task required without the need for O-rings or sealing elements present on prior art products. Creating a simpler to manufacture and maintain device that allow for a user to obtain accurate readings of temperature and pressure while using a minimal amount of tooling. The user is able to remove the protective cap while using only a single tool to prevent dislodgement of the product from the associated port. Current state of the art can potentially place a user in harm as accidental dislodgement of their product can occur having only a single operator.

Abstract: 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.

Abstract: An external defibrillator is customized for at least one person, i.e., an anticipated patient, through creation of a profile for the anticipated patient that allows the defibrillator and users of the defibrillator to provide customized treatment to the patient. The profile may include treatment parameters for the anticipated patient, such as defibrillation therapy parameters selected for the patient. The profile may also include a baseline recording of a physiological parameter of the patient, and medical history and personal information regarding the patient. In some embodiments, the external defibrillator stores a profile for each of one or more anticipated patients within a memory. In other embodiments, a profile for an anticipated patient is stored within a medium associated with that anticipated patient. The medium may, for example, be a removable medium for external defibrillators.

Abstract: A device tests a circuit that is a source of alternating current by measuring at least one electrical parameter of the circuit to determine whether the circuit is able to provide adequate energy for defibrillation by an external defibrillator. The device may test the circuit by applying a load to the circuit, and measuring one or more electrical parameters when the load is applied to the circuit. The device may be the external defibrillator itself, or a separate testing device. In some embodiments in which an external defibrillator tests a circuit, the defibrillator modifies a value of at least one therapy delivery parameter for a subsequent delivery of one or more defibrillation pulses based on the measured electrical parameter value measured. By modifying a therapy delivery parameter, the defibrillator may deliver defibrillation pulses at an energy level that is supportable by the circuit.

The dielectric component may be proximate to the feed-through conductor and may be oriented such that a primary dimension of the dielectric component is substantially parallel to the feed-through conductor. Another embodiment may include a bus. The invention may also be embodied as methods for assembling electromagnetic filters.

Preferably, the emitter and receiver are positioned so that a controller's IR emitter aligns with the IR receiver of an identical controller when the controllers are positioned face to face. In some embodiments, the controller provides audible and visual feedback to users when operating in a learning mode.
