Abstract:
PROBLEM TO BE SOLVED: To provide a medical device for assisting a user to manually perform chest compression to a patient as part of resuscitation of heart.SOLUTION: A medical device includes: a feedback device configured to generate a feedback cue and to assist a user to set an opportunity for performing chest compression; and a processor, a memory, and a related circuit that are configured to determine a cue opportunity for allowing the feedback device to generate the feedback cue. The feedback cue includes two or more phases discriminable by the user. A first phase corresponds to an upstroke phase of rescuer's movement, and a second phase of the feedback cue corresponds to a downstroke of the rescuer's compression movement.
Abstract:
PROBLEM TO BE SOLVED: To provide a multi-path transthoracic defibrillator.SOLUTION: The defibrillator includes three or more electrodes applied to the thorax of a patient to establish at least two electrical paths passing the heart across the thoracic cavity of the patient. A defibrillation waveform across each of the at least two electrical paths is generated, the area of each of the electrodes through which the waveforms are generated may be less than 70% of the projected area of the heart, and the sum of the areas of the electrodes on the same side of the thoracic cavity may be greater than 80% of the projected area of the heart.
Abstract:
PROBLEM TO BE SOLVED: To provide an electrode assembly for an external cardiac pacing and an external cardiac monitoring, the assembly being capable of reducing effect of stimulation artifact on physiological monitoring.SOLUTION: First and second electrodes for external monitoring that are selected from three or more electrodes for monitoring so as to reduce effect of the electrical artifact on a differential signal are disposed so that the electrical artifact generated by pulse for pacing is offset in a signal made of a detected potential. The three or more electrodes for monitoring include two or more electrodes for monitoring located at a different distance from one of the electrodes for stimulation. The first electrode for monitoring is selected from the two electrodes located at the different distance.
Abstract:
PROBLEM TO BE SOLVED: To reduce a signal artifact in a physiological signal resulting from chest compressions.SOLUTION: An apparatus for analyzing a physiological signal during application of chest compressions includes: a mean for acquiring a physiological signal during application of chest compressions; a means for acquiring the output of a velocity sensor configured to detect the velocity of chest compressions; and a means for using the output of the velocity sensor to reduce at least one signal artifact in the physiological signal resulting from the chest compressions.
Abstract:
PROBLEM TO BE SOLVED: To provide a method of automatically determining which type of treatment is most appropriate for a patient. SOLUTION: The method includes steps of: transforming one or more time domain measurements from the patient into frequency domain data representative of the frequency content of the time domain measurements; processing the frequency domain data to form a plurality of spectral bands, the content of a spectral band representing the frequency content of the measurements within a frequency band; forming a weighted sum of the content of the spectral bands, with different weighting coefficients applied to at least some of the spectral bands; and determining the type of treatment based on the weighted sum.

Abstract:
An example of a context sensitive guidance (CSG) system for guiding caregivers providing medical care for a victim, for example a trauma victim, includes a CSG engine and contextual data sources communicatively coupled to the CSG engine. The contextual data sources include a medical device configured to collect physiologic data and provide the physiologic data to the CSG engine and an emergency environment data source configured to receive emergency environment data and provide the data to the CSG engine. The CSG engine includes hardware logic and/or software logic configured to receive the contextual data, evaluate protocols based on the contextual data, select at least one action item based on the protocols, generate at least one instruction based on the action item(s), the instruction(s) including a caregiver instruction and/or a medical device instruction, and provide the instruction to a caregiver interface device and/or the medical device.
Abstract:
A system for consolidating medical data from multiple devices involved in a patient encounter is provided. The system includes a mobile computing device that acquires, via a medical device interface, identifiers of each medical device, generates association information including the one or more identifiers, and transmits the association information to a server. The server receives and stores one or more medical device case files from the medical devices, receives the association information from the mobile computing device, associates the one or more medical device case files with one another, and produces an integrated data source encounter structure including case data from the one or more medical device case files for subsequent processing.
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) are described herein. A method for managing cardiopulmonary resuscitation (CPR) treatment to a person in need of emergency assistance includes monitoring, with an electronic medical device, a parameter that indicates a quality level of a CPR component being provided to the person by a user; determining, with the electronic medical device, that the parameter indicates that the quality level of CPR being provided is inadequate; and providing, to one or more rescuers of the person, an audible, visual, or tactile indication that a different person should perform the CPR component.
