摘要:
External pacemaker systems and methods deliver pacing waveforms that minimize hydrolysis of the electrode gel. Compensating pulses are interleaved with the pacing pulses, with a polarity and duration that balance the net charge at the electrode locations. The compensating pulses are preferably rectangular for continuous pacing, and decay individually for on-demand pacing.

摘要:
Medical devices, software and methods are provided, for making a decision as to whether to administer electric shock therapy to a patient. The decision is made with respect to ECG data that is discounted at least partially, and sometimes even completely, if it occurs during a transition between chest compression group and a pause for ventilation.
摘要:
In general, the invention is directed to techniques for determining appropriate first aid and applying first aid that is appropriate. A first aid system receives patient status information from an input device or a sensor, and presents first aid information as a function of the received patient status information. The first aid system may be incorporated with an external defibrillator. The first aid system may acquire patient status information through an interaction with an operator, in which the first aid system asks the operator to supply patient status information. In one embodiment of the invention, the operator may supply patient status information by touching a diagram representing at least a portion of a human body.

摘要:
An apparatus and method for delivering an external shock pulse receive pacing pulses generated by a first device and a shock pulse generated by a second device. An output of the apparatus is coupled to patient electrodes and the apparatus controls delivery of the received pacing pulses to the output and delivery of the received shock pulse to the output. A control module, pacing control and shock control included in the apparatus cooperatively control delivery of the received shock pulse to the output at a predetermined delay after one of the received pacing pulses.

Integrated devices for performing external chest compression (ECC) and defibrillation on a person and methods using the devices. Integrated devices can include a backboard, at least one chest compression member operably coupled to the backboard, and a defibrillator module operably coupled to the backboard. The integrated devices can include physiological sensors, electrodes, wheels, controllers, human interface devices, cooling modules, ventilators, cameras, and voice output devices. Methods can include defibrillating, pacing, ventilating, cooling, and performing ECC in an integrated, coordinated, and/or synchronous manner using the full capabilities of the device. Some devices include controllers executing methods for automatically performing the coordinated activities utilizing the device capabilities.
摘要:
An external defibrillator for applying a multiphasic defibrillation pulse to a patient uses a single semiconductor switching element in combination with a relay switching element. The semiconductor switching element is used to stop the flow of current from the energy storage device to the patient in between the phases of the multiphasic defibrillation pulse. The relay element is used to switch the leads of the energy storage device so as to create the different phases of the multiphasic defibrillation pulse. In various examples, the relay element is shown to be in the form of: a double-pole, double-throw relay; two single-pole, double-throw relays; or four reed relays. The timing between the activation of the semiconductor switching element and the relay switches may be delayed, so as to give the relatively slower relay switches time to respond. In the embodiment utilizing the two single-pole, double-throw relays, in the resting positions the relays may be coupled to the same terminal of the energy storage device, and a pair of diodes may be used so as to prevent short circuiting of a defibrillation pulse from a second defibrillator.
