Abstract: A training apparatus (500) for use with an external defibrillator is provided, the external defibrillator being responsive to a first electrode and a second electrode, including: a transparent layer having a first electrode attachment region defining an opening sized to receive the first electrode; a signal conductor disposed proximate the first electrode attachment region, the signal conductor having a transfer path, the transfer path operable to provide communication between the first electrode and the second electrode, when the first electrode and the second electrode are disposed on the training apparatus; and a two-dimensional representation of an anterior portion of a defibribation subject, identificable through the transparent layer, having the first electrode attachment region arranged thereon in a manner that defines a preferred plancement area of the first electrode on the defibrillation subject.

Abstract: A wearable compact, lightweight, noninvasive, wearable “unified” device or system (10), that does not compromise a user's motion and flexibility, detects, processes, analyzes and reports predetermined physical states of a human body. The system includes at least one pair of sense electrodes (14) and one reference electrode (16), each configured to be adhesively attached to a surface of the body (30). An electronics module (12) is in electrical communication with each of the electrodes, includes a power source, and processes and analyzes signals provided by the electrodes. The plurality of electrodes and the electronics module are covered by a single adhesive membrane (20) that enables the wearable device to adhere to the surface of the body.

Abstract: A method and apparatus for training a user to operate an external defibrillator, usable in a therapy or training mode, which includes an energy source; an electrode interface responsive to an electrode arrangeable on a release liner and configured for placement on a subject; and an energy delivery system operable to selectively deliver electrical energy from the energy source to the electrode via the electrode interface. The method includes: when the electrode is coupled to the electrode interface, receiving an input signal from the electrode, prior to placement of the electrode on the subject; based on the input signal, identifying a degree of electrical connectivity along an electrical path including the electrode; based on the determined degree of electrical conductivity, advancing the external defibrillator from a first training state to a second training state; and issuing a training state notification indicating advancement from the first training state to the second training state.

Abstract: A system in which one or more alarm sources (10), can wirelessly communicate with a receiver (30), to activate an alarm and does not contain any identification that indicates the communication's source (10). The system may include “repeaters” (40), whose function is to relay the communication from one station to another over distances longer than can be reached by a single transmitter (10), Apparatuses for transmitting (10), repeating (40), and receiving (30), are also disclosed, as well as a communication system comprised of various elements of these.

Abstract: An ambulatory physiological monitor (10) is provided. The monitor includes at least one sensor for detecting at least one physiological parameter of a patient and a housing (42) adapted to be secured to the patient. A circuit (50) is located in the housing for receiving and processing a signal representative of the physiological parameter from the sensor to generate recordable physiological data and for determining if the data exceeds a preestablished alarm limit. An event indicator (12) is coupled to the housing for notifying the patient when the alarm limit has been exceeded. A wireless transmitter (28), operationally coupled to the circuit, is located in the housing for transmitting an emergency notification when the alarm limit has been exceeded. A patient-operable actuator (22) is coupled to the housing for preventing transmission of the emergency notification by the wireless transmitter upon activation by the patient within a predetermined time after the alarm limit has been exceeded.

Abstract: A defibrillation circuit generates a defibrillation pulse and includes a patient-parameter compensator that causes the pulse to have a predetermined characteristic regardless of the value of a patient parameter. For example, the circuit can generate defibrillation pulses that have a desired shape, decay rate, voltage level, current level, and/or energy level regardless of the patient impedance. Consequently, a defibrillator that includes the circuit is likely to be more effective than prior defibrillators in restoring normal heart rhythms to patients having an atypical value for a parameter such as impedance.
