Embodiments are directed to a medical device, such as a defibrillator, for use with an accessory capable of collecting a parameter of a patient. The medical device is capable of at least performing a basic functionality, an advanced functionality, and of defibrillating the patient. The medical device includes an energy storage module within a housing for storing an electrical charge that is to be delivered to the patient for the defibrillating. The medical device includes a processor structured to determine whether a data set received from the accessory confirms or not a preset authentication criterion about the accessory. Although when the accessory is coupled to the housing the medical device is capable of the defibrillating and the basic functionality, the medical device is capable of the advanced functionality only when the accessory is coupled to the housing and it is determined that the preset authentication criterion is confirmed. Embodiments also include methods of operation and a programmed solution.

In some embodiments, a wearable medical device system includes a processor configured to determine whether a patient requires electrical therapy to be provided via a plurality of therapy electrodes, the electrical therapy comprising discharging at least a portion of a stored electrical charge from an energy storage module, and if so, cause a fluid deploying mechanism to deploy a portion of the stored fluid to an interface between at least two therapy electrodes and the patient's skin prior to providing the electrical therapy, the deployed portion of fluid adapted to decrease the impedance measured by an impedance measurement circuit, and cause the fluid deploying mechanism to deploy an additional portion of fluid in response to the impedance measured by the impedance measurement circuit increasing above a threshold during the electrical therapy.

Wearable cardiac defibrillator (WCD) system controlling conductive fluid deployment

Patient electrodes, patient monitors, defibrillators, wearable defibrillators, software and methods may warn when an electrode stops being fully attached to the patient's skin. A patient electrode includes a pad for attaching to the skin of a patient, a lead coupled to the pad, and a contact detector that can change state, when the pad does not contact fully the skin of the patient. When the detector changes state, an output device may emit an alert, for notifying a rescuer or even the patient.

Alerting for loss of full skin contact of patient electrodes

A wearable cardiac defibrillator ('WCD') system may include a support structure that a patient can wear, an energy storage module that can store an electrical charge, and a discharge circuit that can discharge the electrical charge through the patient so as to shock him or her, while the patient is wearing the support structure. Embodiments may actively take into account bystanders, both to protect them from an inadvertent shock, and also to enlist their help. In some embodiments, the WCD system includes a speaker system and a memory. Prompts have been saved in advance in the patient's own voice, and stored in the memory. In case of an emergency, the prompts may be played by the speaker system in the patient's own voice, and heard by a bystander.

In embodiments, a wearable cardiac defibrillator system includes an energy storage module configured to store a charge. Two electrodes can be configured to be applied to respective locations of a patient. One or more reservoirs can store one or more conductive fluids. Respective fluid deploying mechanisms can be configured to cause the fluids to be released from one or more of the reservoirs, which decreases the impedance at the patient location, and decreases discomfort for the patient. In some embodiments an impedance is sensed between the two electrodes, and the stored charge is delivered when the sensed impedance meets a discharge condition. In some embodiments, different fluids are released for different patient treatments. In some embodiments, fluid release is controlled to be in at least two doses, with an intervening pause.

Techniques for routing event data from a field device, such as an external defibrillator, to a selected subset of a plurality of possible destinations are described. The event data may include physiological data of the patient, such as a 12-lead electrocardiogram (ECG). The destinations may be associated with one of a plurality of patient treatment centers, and may include, as examples, computing device, printers, displays, personal digital assistants, or web-accessible accounts. In some examples, a server maintains user-configurable information or rules for at least some of the destinations, and uses the information or rules for determining whether event data received from a field device is routed to the destination. In some examples, the server may also make the routing determination based on an analysis of event data, such as a determination as to whether the event data indicates that the patient is suspected to be experiencing an acute myocardial infarction.

Selectively routing patient data between field devices and treatment center destinations

A wearable cardiac defibrillator ('WCD') system may include a support structure that a patient can wear, an energy storage module that can store an electrical charge, and a discharge circuit that can discharge the electrical charge through the patient so as to shock him or her, while the patient is wearing the support structure. Embodiments may actively take into account bystanders, both to protect them from an inadvertent shock, and also to enlist their help. In some embodiments the WCD system includes a speaker system that transmits a sound designed to assist a bystander to perform CPR. Optionally CPR chest compressions received by the patient can be further detected, and feedback can be given. In embodiments, a WCD system may include a user interface that can be controlled to output CPR prompts tailored to a skill level of the bystander.

Integrated devices for performing external chest compression (ECC) and defibrillation on a person and methods using the devices. Integrated devices can include a backboard, at least one chest compression member operably coupled to the backboard, and a defibrillator module operably coupled to the backboard. The integrated devices can include physiological sensors, electrodes, wheels, controllers, human interface devices, cooling modules, ventilators, cameras, and voice output devices. Methods can include defibrillating, pacing, ventilating, cooling, and performing ECC in an integrated, coordinated, and/or synchronous manner using the full capabilities of the device. Some devices include controllers executing methods for automatically performing the coordinated activities utilizing the device capabilities.

Integrated external chest compression and defibrillation devices and methods of operation

A method for operating a defibrillator including an aural output device includes causing the output device to deliver a first verbal instruction which includes a prompt to call an emergency response system; determining if the user elects to have the defibrillator continue on to a second instruction; and if it is determined that the user elects to have the defibrillator continue on to the next instruction, causing the defibrillator to deliver the second verbal instruction. In an exemplary embodiment, the step of determining if the user elects to continue on to the second instruction includes the step of determining if the user has performed an action upon the defibrillator.

Visual and aural user interface for an automated external defibrillator

Time after time studies find that often, even when administered by trained professionals, cardiopulmonary resuscitation (CPR) compression rates and depth are inadequate. Too week, shallow or too forceful compressions may contribute to suboptimal patient outcome. Several parameters are crucial for optimal and properly-administered CPR. Crucial parameters include proper hand positioning on the patient's chest, depth of compression of 4-5 cm, and compression rate of 100 compressions per minute. The crucial parameters are often affected by patient parameters, and relative to the patient, rescuer parameters, such as patient thoracic volume; weight; age; gender; and rescuer's, relative to the patient's, parameters, such as weight, height; physical form, etc. Proposed is an automated CPR feedback device with user programmable settings for assisting with real-time feedback and subsequently correcting rescuers patient customized CPR technique.

Programmable cardiopulmonary resuscitation (CPR) detection device

A medical device and/or a method are used by a rescuer who is caring for a patient. The depth of CPR chest compressions is determined, by detecting magnetic fields. An interference is sensed, which is not associated with the CPR chest compressions, but which is superimposed on the detected magnetic fields. Appropriate countermeasures may be taken, if the sensed interference is larger than a threshold.

Alerting users of CPR feedback device of detected magnetic interference

Methods and apparatus are provided for determining a defibrillation treatment protocol in an external defibrillator whereby a user may override a CPR-first default protocol. The method includes following steps configured in a defibrillator controller of issuing an inquiry; waiting for a response to the inquiry for a set time; ordering a CPR treatment protocol if no response is received within the set time; analyzing a response; ordering a CPR treatment protocol upon receiving a non-affirmative response to the inquiry; and ordering a shock treatment protocol upon receiving an affirmative response to the inquiry. Upon selecting a shock treatment protocol, the defibrillator performs a shock analysis under the shock treatment protocol, and either orders a CPR treatment protocol if shock treatment is not indicated by the shock analysis or provides a defibrillation shock if shock treatment is indicated by the shock analysis. Queries may be presented to a user in visual, audible, or both visual and audible format.

Detecting loss of full skin contact in patient electrodes

A wearable medical device includes a garment and a medical device. The medical device has a functionality that can transition between an operative state and an inoperative state. When the functionality is in the inoperative state, a protrusion extends so as to poke the patient, as an indication that steps need to be taken to make the device ready for use.

Wearable cardiac defibrillator (WCD) poking the patient when not ready for use

A wearable cardiac defibrillator ('WCD') system may include a support structure that a patient can wear, an energy storage module that can store an electrical charge, and a discharge circuit that can discharge the electrical charge through the patient so as to shock him or her, while the patient is wearing the support structure. Embodiments may actively take into account bystanders, both to protect them from an inadvertent shock, and also to enlist their help. In some embodiments, the WCD system includes a speaker system, a memory and a proximity detector. Prompts have been stored in the memory. In case of an emergency, upon inferring that no bystander is nearby, the speaker system may transmit a sound at a higher intensity than otherwise, hoping to attract attention.
