Appl. No.:

7/999495

International Classification:

G01N 3348
A61B 500

US Classification:

25022723

Abstract:

A method and system for controlling the intervals during which light signals are sampled in a fiber-optic sensing system compensates for signal artifacts that are caused by movement of the fiber-optic waveguide during the sampling. The method and system sample the light signals at intervals that are shorter than the intervals during which displacement of the optical waveguide occurs in normal use. The short-sampling intervals result in the individual sampling of different wavelengths of light being exposed to the same changes in transmission characteristics of the optical waveguide which causes signal artifacts. Accordingly, when subsequent processing of the collected signals occurs, the effects of the signal artifacts are compensated for.

International Classification:

G16H 50/30

Abstract:

Systems, devices, and methods provide up-to-date defibrillation shock recommendations. In an example method, multiple segments of an electrocardiogram (ECG) of an individual are detected from an individual receiving chest compressions. The multiple segments are evaluated to determine whether the individual is exhibiting a shockable heart rhythm. A medical device outputs a recommendation indicating whether a defibrillation shock is advised based on the most recent determination of the individual's heart rhythm. For example, the medical device outputs an up-to-date recommendation on-demand in response to an input signal from a user. In some examples, the medical device updates the recommendation based on ongoing analysis of the ECG.

International Classification:

A61N 1/39

Abstract:

Defibrillators with enhanced functionality during cardiopulmonary resuscitation (CPR) periods are described. The enhancements include predicting a length of a charging period of a capacitor of the medical device so that capacitor is shock charged at the end of the CPR period. The enhancements also include re-assessing an electrocardiogram (ECG) signal for continued presence of a shockable rhythm during the CPR period and before administration of a defibrillation shock. Together the enhancements can improve the timing and recommended administration of defibrillation therapy.

International Classification:

A61N 1/39
G16H 20/30
G16H 40/63

Abstract:

Systems, devices, and methods for detecting and addressing irregular motion to improve defibrillation shock recommendations are described. In an example method performed by a medical device, an electrocardiogram (ECG) of an individual receiving chest compressions is detected. In addition, irregular motion of the individual is detected. If a magnitude of the irregular motion is greater than or equal to a threshold, a remedial action is performed. In some examples, the medical device refrains from generating a recommendation indicating whether the ECG includes a shockable rhythm and/or whether a defibrillation shock is recommended. In some instances, the medical device outputs the recommendation with a certainty of the recommendation. In some cases, the medical device outputs a warning and generates the recommendation in response to receiving an input signal indicating a manual override.

International Classification:

G16H 40/40
G06F 8/654
G06F 21/57

Abstract:

Systems and techniques to ensure reliable operation of devices, such as medical devices, that are configured to execute installed software are described. A secure software update process for the device utilizes multiple integrity checks in order to prove that software integrity has not been compromised before the device is allowed to be put into service with the software installed thereon. Also described is a computer architecture for an external defibrillator that isolates the execution of installed software applications by separately compiling the code for those applications and by executing the separately-compiled applications on different processors of the defibrillator. Among other things, this allows the defibrillator to be “brought online” faster, such as to deliver a shock to a patient.

Abstract:

An event-driven medical treatment data notification system is disclosed. Embodiments are directed to a system for transmitting medical treatment data, such as AED device events, waveforms, and device location information, to recipients that have registered to receive the data. In specific embodiments, the data is recorded by medical devices in the course of treatment during a medical incident. In specific embodiments, recipients register to receive treatment data in response to certain events. The treatment data is transmitted to any registered recipients in response to the occurrence of certain events.
