Abstract:
A resuscitation system for use in resuscitation of cardiac arrest victims includes an ECG monitor programmed to monitor an organized, non-shockable rhythm of an electrocardiogram (ECG) signal from a patient undergoing lifesaving cardiac care; a processor programmed to identify a time during an electrocardiographic cycle of the ECG signal during which a vulnerable period for risk of fibrillation induction of the ECG will occur; and control circuitry for generating signals to cause a parameter descriptive of chest compressions to be modified so as to minimize risk of induction of fibrillation during the vulnerable period.
Abstract:
A medical ventilation monitoring system includes a patient ventilation unit defining an airflow path, the unit arranged so that when the unit is applied to a patient, the airflow path is in fluid communication with the patient's airway; an airflow sensor in the air flow path positioned to sense the presence of ventilation airflow to or from the patient; and a wireless transceiver arranged to receive data that is generated by a portable medical device, and to use the data to provide feedback to a rescuer regarding proper administration of ventilation.
Abstract:
Systems and methods related to the field of cardiac resuscitation, and in particular to devices for assisting rescuers in performing cardio-pulmonary resuscitation (CPR).
Abstract:
A resuscitation system for use by a rescuer for resuscitating a patient having a ventricular arrhythmia, comprising circuitry and processing configured for detection of chest compression/phase timing information indicative of the start of the decompression phase, circuitry and processing configured for delivery of eletromagnetic therapy for the termination of ventricular arrhythmias, wherein the circuitry and processing for the delivery of electromagnetic therapy utilizes the chest compression phase timing information to initiate delivery of the electromagnetic therapy within 300 milliseconds of the start of the decompression phase.
Abstract:
A medical device of the type used for assisting a user in manually delivering repetitive therapy to a patient (e.g., chest compressions or ventilations in cardiac resuscitation), the device comprising a feedback device configured to generate feedback cues to assist the user in timing the delivery of the repetitive therapy, at least one sensor or circuit element configured to detect actual delivery times, at which the user actually delivers the repetitive therapy, and a processor, memory, and associated circuitry configured to compare the actual delivery times to information representative of desired delivery times to determine cue times at which the feedback cues are generated by the feedback device.

Abstract:
A computer-implemented method of recording the times of events related to the medical care delivered to patient (11), and for integrating those times to provide a patient history, including recording a first time of occurrence of a first event, recording first clock information characterizing a first time source from which the first time of occurrence was obtained, recording a second time of occurrence of a second event, recording second clock information characterizing a second time source from which the second time of occurrence was obtained, wherein the first time source and the second time source are independent of one another and not synchronized with one another, transferring recorded data so that the first time of occurrence, first clock information, second time of occurrence, and second clock information are accessible at a computer (4); and producing a patient history using at least the first and second times of occurrence.
Abstract:
A portable electronic device for recording medical data, including a display, electronics for displaying a user interface on the display and for responding to user inputs entered on the device, and electronics for determining the environment in which the device is being used, wherein the user interface is varied in, accordance with the determined environment.
Abstract:
A color display device comprising at least two substrates (12, 14) spaced from each other, the substrates each having an internal and an external surface, the internal surfaces of the two substrates facing each other, at least one of the substrates being transparent; electrodes positioned to establish a field in the space between the two substrates; an optically active material (22) occupying at least a portion of the space between the two substrates and having optical properties influenced by the field; a color filter layer (32) comprising color filter elements that alter the color of light traveling through the color filter layer, the color filter elements being positioned outside of the space between the two substrates; and a three-dimensional black mask (26, 28, 30) comprising mask elements aligned with the boundaries between adjoining color filter elements. The three-dimensional black mask structure allows the color filter to be placed on the exterior of the display while still maintaining good color performance under off-axis viewing conditions.
Abstract:
The invention provides a thin, lightweight, durable electro-optic display assembly (1) that is significantly more flexible than known plastic electro-optic display element that contains an electro-optic material (2), disposed between two substrates (3) that are bonded together, such as by a gasket (4). The enhanced flexibility of the plastic display assemblies according to the invention is achieved by employing laminate display structures in which there is little, if any, bonding between adjacent layers of the laminate assembly.
