A CPR machine () is configured to perform, on a patient's () chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (), and a driver system () configured to drive the compression mechanism. A force sensing system () may sense a compression force, and the driving can be adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (). An optional chest-lifting device () may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected.

CPR chest compression machine adjusting motion-time profile in view of detected force

In embodiments, a CPR chest compression system includes a retention structure that can retain the patient's body, and a compression mechanism that can perform automatically CPR compressions and releases to the patient's chest. The compression mechanism can pause the performing of the CPR compressions for a short time, so that an attendant can check the patient. The CPR system also includes a user interface that can output a human-perceptible check patient prompt, to alert an attendant to check the patient during the pause. An advantage can be when the attendant checks in situations where the condition of the patient might have changed, and an adjustment is needed. Or in situations where the patient may have improved enough to where the compressions are no longer needed.

CPR chest compression system periodically reminding attendant to check patient

A person living with an increased risk of a potentially life threatening condition that could at any moment render the person incapacitated, may find it stressful to be left alone for any length of time even if wearing a monitoring and/or treatment device. Wearers of monitoring and/or treatment systems may find it reassuring that should they become incapacitated when the monitored event occurs, the monitoring system can obtain information during the 'blind' time, that is the time between the event onset and rescue arrival. An event assistant device, responsive to a wearable monitoring device's detection of an event, can navigate to the wearable monitoring device and capture visual and/or audio information for handoff to a designated rescuer.

Autonomous event assistant device

In one embodiment, a method to track cardiac health of a patient is described. The method includes communicating, via a mobile device, to a cardiac device worn by the patient, wherein the cardiac device includes at least one sensor. The method also includes receiving cardiac device data from the cardiac device and filtering the cardiac device data based at least in part on patient logic rules. The method includes pushing the cardiac device data to one or more personnel based at least in part on the patient logic rules.

Wearable device network system

Augmented, virtual, and/or mixed reality applications in optimizing a fitting process and a fit of wearables, including wearable cardioverter defibrillators, to a wearer's body.

Assistant for garment and wearable device fitting

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.

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.

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.

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.

A CPR machine () is configured to perform compressions on a patient's () chest that alternate with releases. The CPR machine includes a compression mechanism (), and a driver system () configured to drive the compression mechanism. A compression force may be sensed, and the driving is adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (). An optional chest-lifting device () may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected. An advantage is that a changing condition in the patient or in the retention of the patient within the CPR machine may be detected and responded to.
