System and methods for delivering defibrillator incident information to a PSAP in real-time during emergency use of an AED are described. Such information is utilized by a telecommunicator at a PSAP to provide better guidance to volunteer caregivers during potential cardiac arrest incidents. In another aspect the AED's current instruction state and optionally the time in that state is provided to the PSAP.

The present invention relates to a device, and software and methodology associated with a portable Automated External Defibrillator (“AED”). The portable AED works with a mobile device and software, and includes two or more cardiac pads, a battery pack, and specialized capacitor. When connected to a patient in cardiac arrest, the AED contacts Emergency Medical Services, and records patient information to be transmitted for evaluation by medical providers. The AED is able to analyze cardiac rhythms, suggests administering one or more shocks to the patient in appropriate cardiac arrhythmia, and guides a user on proper CPR technique, if enabled. The AED software can alert other personnel via a mobile device app.

An in-vehicle automated external defibrillator system and a method of controlling the same, for detecting a state of a driver and applying an electric shock to his or her heart in the event of emergency, are disclosed. The method of controlling the in-vehicle automated external defibrillator system includes determining, by a driver state recognition device, a state of a driver through a state determination device, upon determining that the driver is in a cardiac arrest state, determining, by a heart impulse position controller, two current pads among a plurality of current pads disposed in a seat belt, determining, by a heart impulse intensity controller, current to be applied through the two determined current pads, and applying, by the heart impulse intensity controller, the determined current through the two determined current pads.

In embodiments, a wearable cardiac defibrillation (WCD) system includes one or more flexible ECG electrodes. The WCD system may have a support structure that is dimensioned to be worn so as to press the electrodes towards the body of the patient. The electrodes may be made from appropriate material so as to flex in order to match a contour of the body of the patient. An advantage over the prior art is that the flexible electrode may make better electrical contact with the patient's skin, and therefore provide a better ECG signal for the WCD system to perform its diagnosis.

A system and method for reducing and preventing head injuries using a combination of hardware and software. Elevated neck stiffness can be learned through the system, device, and the method described in the present invention by delivering and pairing a certain appropriate sensory cue (SnC) with a certain appropriate significance cue (SgC). the system, device, and method are used to generally facilitate and validate an increase in neck stiffness to prevent or reduce the likelihood of concussion upon impact. The system employs a combination of hardware and software, such as using modified virtual reality (VR) headsets (in both hardware and software), to deliver visual, auditory, and other cues (somatosensory, vestibular, etc.) as SnC. The system also employs a combination of hardware and software, such as using modified virtual reality (VR) headsets (in both hardware and software), to deliver somatosensory, vestibular, visual, auditory, and other cues as SgC.

A medical device includes a sensor interface for measuring one or more physiological signals of the patient; at least one motion detector for detecting movement of the device; a processor coupled to the sensor interface and the at least one motion detector; and a memory communicatively coupled to the processor and comprising instructions that cause the processor to receive movement information comprising at least acceleration information and heading information from the at least one motion detector; detect movement of the medical device from the movement information, wherein the movement of the medical device comprises a distance traveled by the medical device and a direction traveled by the medical device; and estimate a current location of the medical device relative to a previous location of the medical device using dead reckoning based at least in part on the distance and direction traveled by the medical device.

Embodiments of a wearable cardioverter defibrillator (WCD) system are configured to monitor a patient's ECG for shockable arrhythmias and deliver a shock to the patient in response to such a detection. To monitor the patient's ECG with reduced signal noise to improve the system's performance, the system includes a cable assembly having: a signal line; an inner shield and an outer shield; an ECG electrode electrically connected to the signal line of the cable assembly; and an amplifier having first and second input nodes respectively connected to the signal line and the outer shield of the cable assembly. The amplifier's output node is electrically connected to the inner shield of the cable assembly to reduce the reactive load seen by the patient's heart in driving the ECG sensing circuitry, which reduces the noise on the ECG signal outputted by the amplifier.

Embodiments of this disclosure are directed to a wearable cardioverter defibrillator (“WCD”) system design in which a WCD implements an alert prioritization scheme to provide the patient with feedback in an order that is less likely to cause confusion. Different conditions (e.g., device status, equipment condition, or physiologic condition) are prioritized based on an analysis of severity of the condition and timeliness of user action needed. The prioritization scheme defines what alert, if any, is presented to the user by the WCD system as a result of various conditions. Generally stated, an alert for the highest priority condition currently detected is presented to the user and maintained until that condition either changes or becomes surpassed in the prioritization scheme.

A wearable arrhythmia monitoring and treatment device for improving confidence in determined arrhythmias prior to treatment includes a plurality of sensing electrodes, one or more therapy electrodes, and an electrode signal acquisition circuit having a plurality of inputs. The electrode signal acquisition circuit is configured to sense a respective signal provided by each of a plurality of different pairings of the plurality of sensing electrodes. The wearable arrhythmia monitoring and treatment device includes a monitoring and detection circuit including at least one processor configured to analyze the respective signals provided by each of the plurality of different pairings of the plurality of sensing electrodes, change a confidence level in a determined arrhythmia condition based on the respective signals provided by the plurality of different pairings of the plurality of sensing electrodes, and initiate a therapy to the patient via the one or more therapy electrodes based on the confidence level.

A method may include initializing one or more cameras on an external electrode assembly including a pair of electrodes. The method may further include capturing image information via the one or more cameras, the image information comprising a series of images acquired by the one or more cameras. The method may further include, based at least in part on the image information, providing feedback, comprising at least one of visual feedback and audio feedback, on at least one output device to guide the rescuer in the treatment of the patient.
