Abstract:
An apparatus for assisting a rescuer in performing chest compressions during CPR on a victim, the apparatus comprising a pad or other structure configured to be applied to the chest near or at the location at which the rescuer applies force to produce the chest compressions, at least one sensor connected to the pad, the sensor being configured to sense movement of the chest or force applied to the chest, processing circuitry for processing the output of the sensor to determine whether the rescuer is substantially releasing the chest following chest compressions, and at least one prompting element connected to the processing circuitry for providing the rescuer with information as to whether the chest is being substantially released following chest compressions.
Abstract:
Systems and methods of providing life support are provided. A life support system includes a first life support device that has a control unit and is configured to apply a life support protocol to a subject. The first life support device also includes a memory unit that can store life support protocol information, and the control unit can provide the life support protocol information to a second life support device. The control unit can also receive operating instructions from the second life support device based on the life support protocol information, and can implement the operating instructions.
Abstract:
A method of analyzing a physiological (e.g., an ECG) signal during application of chest compressions. The method includes acquiring a physiological signal during application of chest compressions; acquiring the output of a sensor from which information on the velocity of chest compressions can be determined; and using the information on the velocity to reduce at least one signal artifact in the physiological signal resulting from the chest compressions.
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.
Abstract:
Electrodes and circuitry for monitoring and stimulating the exterior of the human body, comprising delivering stimulation pulses to stimulation electrodes applied to the exterior of the body, detecting an electrical potential at monitoring electrodes applied to the exterior of the body, positioning at least a first and second monitoring electrode at locations at which an electrical artifact caused by the electrical stimulation pulses is substantially cancelled in a signal formed from the electrical potentials detected at the first and second monitoring electrodes.
Abstract:
Systems and methods of processing raw electrocardiogram (ECG) waveform data of a patient into estimated real-time ECG waveform data. The method includes sensing at least one physical non-cardiac influence on the raw ECG waveform data, constructing a time domain computer model of the at least one physical, non-cardiac influence on the raw ECG waveform data, and adaptively filtering the raw ECG waveform data in the time domain using the constructed time domain computer model of the at least one physical non-cardiac influence on the raw ECG waveform data to form the estimated real-time ECG waveform data. The system can include an ECG device for collecting raw ECG waveform data, at least two ECG electrodes positioned on the patient and electrically coupled to the ECG device, and a processor coupled to the ECG device and configured to compute a time domain model of an artifact created by chest compressions.
Abstract:
A system and method for aiding in the proper placement of ECG electrodes and other resuscitation parameters. The system includes motion sensors disposed on the ECG electrodes, and a defibrillator control system operable to interpret motion signals from the motions sensors to determine that an electrode is in motion, and thus being handled by rescuer setting up the system for use, and, based on this determination, prompt the rescuer to place the electrode in its intended location on the body of the patient. The control system may also be operable to determine relative motion and/orientation of the motion sensors and control resuscitation based on the relative motion and/orientation of the motion sensors.
Abstract:
A system for monitoring performance of a resuscitation activity on a patient by an acute care provider is provided. The system includes: a first wearable sensor configured to sense movement of a first portion of an acute care provider's hand; a second wearable sensor configured to sense movement of a second portion of the acute care provider's hand; and a controller. The controller is configured to: receive and process signals representative of performance of a resuscitation activity from the first sensor and the second sensor; identify from the processed signals information indicative of at least one of a relative distance, a relative orientation, a change in relative distance and a change in relative orientation between the first sensor and the second sensor during performance of the resuscitation activity; and determine at least one resuscitation activity parameter based, at least in part, on the identified information.

Abstract:
Among other things, we describe a system that includes a first medical device for treating a patient at an emergency care scene, the first medical device including a processor and a memory configured to detect a request for a connection between the first medical device and a second medical device for treating the patient at the emergency care scene, the request for connection including an identifier of the second medical device, responsive to receiving the request for connection, enabling a wireless communication channel to be established between the first medical device and the second medical device based on the identifier of the second medical device and an identifier of the first medical device; and enabling transmission and/or exchange of patient data between the first medical device and the second medical device via the wireless communication channel. Such communications with more than two devices may also be possible.
