A61B 5/0265

US Classification:

600380

Abstract:

A medical device including a probe configured to be orally inserted into a lumen extending into the thorax of the subject, a plurality of electrodes, and a control circuit. The probe includes a first electrode. The plurality of electrodes includes at least one second electrode and at least one third electrode configured to be disposed externally on the thorax of the subject on a first side of a sternum of the subject and a second side of the sternum of the subject, respectively, the second side opposite the first side. The control circuit is electrically coupled to the first electrode and the at least one second and third electrodes and configured to measure an impedance between the first electrode and each of the at least one second and third electrodes and determine a ratio of arterial blood volume relative to venous blood volume based upon the measured impedance.

Inventors:

Christopher Luke Kaufman - Somerville MA, US

Assignee:

ZOLL Medical Corporation - Chelmsford MA

International Classification:

A61H 31/00

US Classification:

601 41

Abstract:

A method for providing emergency care to a patient of an adverse cardiac event is disclosed that includes causing multiple chest compressions to be provided to the patient, and causing multiple inducements of ventilation to be provided to the patient. Particular ones of the multiple chest compressions can overlap time-wise with corresponding ones of the multiple inducements of ventilation, and can be substantially out of phase with the corresponding ones of the multiple inducements of ventilation.

Abstract:

A computer-implemented method for providing summary information for lifesaving activities is disclosed. The method involves sensing one or more activities that are repeatedly and cyclically performed on a victim by a rescuer; identifying a cyclical timing interval over which performance is to be analyzed for a integer number of cycles of the one or more activities, and gathering data from the sensing of the one or more activities during the time interval; generating, from analysis of the one or more activities, summary data that condenses data sensed for the one or more activities into a summary of the one or more activities; and providing, for display to a user, a visual summary of the performance of the one or more activities over the identified time interval.

Kent Volosin - Mars PA, US

International Classification:

A61N 1/39
A61N 1/04

Abstract:

A medical device that includes a power source, a therapy delivery interface, therapy electrodes, electrocardiogram (ECG) sensing electrodes to sense ECG signal of a heart of a patient, a sensor interface to receive and digitize the ECG signal, and a processor. The processor is configured to analyze the ECG signal to determine a cardiac rhythm and a transform value representing a magnitude of a frequency component of the cardiac rhythm, analyze the cardiac rhythm and the transform value to detect a shockable cardiac arrhythmia by classifying the cardiac rhythm as a noise rhythm or a shockable cardiac arrhythmia rhythm based on the transform value, and causing the processor to detect the cardiac arrhythmia if classifying the cardiac rhythm as a shockable cardiac arrhythmia rhythm, initiate a treatment alarm sequence, adjust the shock delivery parameter for a defibrillation shock, and provide the defibrillation shock via the therapy electrodes.

International Classification:

A61H 31/00
A61N 1/39

Abstract:

An example of a system for providing emergency care to a patient includes an automated chest compression device configured to engage the patient at the patient's sternum to provide multiple chest compression cycles to the patient's sternum, an automated mechanical ventilation device to induce negative pressure ventilation, and a controller operably coupled to the automated chest compression device and the automated mechanical ventilation device and including one or more processors configured to control the automated chest compression device to cyclically perform chest compressions, and control the automated mechanical ventilation device to cyclically induce the negative pressure ventilation out-of-phase with the chest compressions such that the automated mechanical ventilation device cyclically induces the negative pressure ventilation prior to each compression of the patient's sternum.
