摘要： An external defibrillator with an output circuit having four legs arrayed in the form of an “H” (an “H-bridge”) is disclosed. The output circuit is designed to be able to conduct a range of defibrillation pulse energies, from below 50 joules to above 200 joules. Each leg of the output circuit contains a solid-state switch. By selectively switching on pairs of switches in the H-bridge, a biphasic defibrillation pulse may be applied to a patient. The switches in three of the legs of the H-bridge output circuit are preferably silicon controlled rectifiers (SCRs). Gate drive circuits are coupled to the SCRs to bias the SCRs with a voltage that allows the SCRs to remain turned-on even when conducting low current. The switch in the fourth leg is preferably a pair of insulated gate bipolar transistors (IGBTs) coupled in series. A gate drive circuit is coupled to the gate of the IGBTs to provide a slow turn-on and a fast turn-off of the IGBTs. The gate drive circuit also biases the IGBTs with a sufficient voltage to allow the IGBTs to withstand a shorted discharge of the external defibrillator through the output circuit. The circuit also includes a protective component that has both inductive and resistive properties. An internal energy dump may be performed by biasing on two legs on the same side of the H-bridge output circuit, thus eliminating the need for a separate energy dump circuit.

摘要： An external defibrillator (8) with an output circuit (14) having four legs arrayed in the form of an "H" (an "H-bridge") is disclosed. Each leg of the output circuit contains a solid-state switch (31, 32, 33, 34). By selectively switching on pairs of switches in the H-bridge, a biphasic defibrillation pulse may be applied to a patient. The switches in three of the legs of the H-bridge output circuit are preferably silicon controlled rectifiers (SCRs). Gate drive circuits (51, 53, 54) are coupled to the SCRs to bias the SCRs with a voltage that allows the SCRs to remain turned-on even when conducting low current. The switch in the fourth leg is preferably a pair of insulated gate bipolar transistors (IGBTs) coupled in series. A gate drive circuit (52) is coupled to the gate of the IGBTs to provide a slow turn-on and a fast turn-off of the IGBTs. The gate drive circuit (52) also biases the IGBTs with a sufficient voltage to allow the IGBTs to withstand a shorted discharge of the external defibrillator through the output circuit. The circuit also includes a protective component (27) that has both inductive and resistive properties. The protective component (27) serves to both limit current during a defibrillation pulse, and to absorb energy during an internal energy dump. An internal energy dump is performed by biasing on the switches in two legs on the same side of the H-bridge output circuit (14), eliminating the need for a separate energy dump circuit.

摘要： A medical device and/or a method are used by a rescuer who is caring for a patient. The depth of CPR chest compressions is determined, by detecting magnetic fields. An interference is sensed, which is not associated with the CPR chest compressions, but which is superimposed on the detected magnetic fields. Appropriate countermeasures may be taken, if the sensed interference is larger than a threshold.

摘要： In an embodiment, a medical device can be used with a power adapter system. In addition, it can receive a data set from the power adapter system, and examine the data set to determine whether the data set confirms or not an authentication of the power adapter for use with the medical device. If the authentication is not confirmed, the external medical device can operate differently than otherwise. For example, power can be drawn from the power adapter system only if an inside battery is not charged.

摘要： 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.

摘要： Techniques for initiating direct communication between an emergency medical device, such as an automated external defibrillator (AED) and a safety agency may include detecting an event and contacting the safety agency in response to the detected event and user authorization. For example, the AED may detect an event such as removal of the AED from a mount and alert an operator of the intent to send contact the safety agency. The AED determines whether an override command was received from the operator in a defined amount of time. When the operator does not input an override command, the AED interprets the absence of the override command as user authorization and contacts the safety agency via a communication unit. For instance, the AED may generate an advisory and send the advisory to the safety agency. The initiation of direct communication between the AED and the safety agency by the AED enables the operator to interact with a patient, e.g., perform CPR on the patient.
