A medical device control unit is provided. The control unit may include a communications interface, a memory, and at least one processing device. The processing device may be configured to cause application of a control signal to a primary antenna associated with a unit external to a subject's body. The processing device may further be configured to monitor a feedback signal indicative of the subject's breathing and store, in the memory, information associated with the feedback signal. The processing device may also cause transmission of the stored information, via the communications interface, to a location remote from the control unit. The processing device may further be configured to receive an update signal, from the location remote from the control unit, and cause application of an updated control signal to the primary antenna based on the update signal.

Aspects relate to systems, methods, and apparatuses relating to a portable device that may be used to identify a critical intensity and an anaerobic work capacity of an individual. The device may utilize muscle oxygen sensor data, speed data, or power data. The device may utilize data from multiple exercise sessions, or may utilize data from a single exercise session. The device may additionally estimate a critical intensity from a previous race time input from a user.

A chest-worn sensor device, such as a device for daily at-home monitoring of cardiopulmonary health conditions, includes an audio and/or visual interface that provides cues to assist a user in performing a measurement sequence. The sensor device may detect whether there are any body posture issues or device contact issues. In response to detecting an issue, the sensor device provides and audio and/or visual cue to the user indicating the issue. The sensor device may provide additional cues throughout the measurement sequence, such as a cue that a measurement is being taken, a cue for the user to change body posture, and a cue for the user to remove the sensor device.

A wearable cardioverter defibrillator (WCD) (10) and method (60) comprise a set of electrodes (12) for placement on a subject (14), a mechanism for electrically engaging (16) the set of electrodes to the subject's skin, and at least one non-invasive physiologic sensor (18, 20) configured for placement on the subject. A controller (24) monitors an output of the non-invasive physiologic sensor (18, 20) for detecting a change in a health parameter of the subject being indicative of one or more of a change in subject condition that may be a precursor to potential cardiac arrhythmia or a simultaneously occurring cardiac arrhythmia. Responsive to detecting the change, the controller (24) activates an alarm (26) for requesting a response from the subject (14) within a predetermined time. Responsive to receiving the subject's response within the predetermined time, the controller (24) inhibits the mechanism (16) from electrically engaging the set of electrodes (12) to the subject's skin. Responsive to not receiving the subject's response, the controller (24) initiates the mechanism (16) for electrically engaging the set of electrodes (12) to the subject's skin.

A device for the treatment of snoring is provided. The device may include a flexible substrate configured for removable attachment to a subject's skin, a primary antenna disposed on the flexible substrate, an interface configured to receive a feedback signal that varies based upon a breathing pattern of the subject; and at least one processing device. The processing device may be configured to analyze the feedback signal and determine whether the subject is snoring based on the analysis of the feedback signal, and if snoring is detected, cause a hypoglossal nerve modulation control signal to be applied to the primary antenna in order to wirelessly transmit the hypoglossal nerve modulation control signal to a secondary antenna associated with an implant unit configured for location in a body of the subject.

A non-invasive method of estimating intra-cranial pressure (ICP). The method including the steps of: a. non-invasively measuring pressure pulses in an upper body artery; b. determining central aortic pressure (CAP) pulses that correspond to these measured pressure pulses; c. identifying features of the ICP wave which denote cardiac ejection and wave reflection from the cranium, including Ejection Duration (ED) and Augmentation Index of Pressure (PAIx); d. non-invasively measuring flow pulses in a central artery which supplies blood to the brain within the cranium; e. identifying features of the measured cerebral flow waves which denote cardiac ejection and wave reflection from the cranium as Flow Augmentation Index (FAIx); f. calculating an ICP flow augmentation index from the measured central flow pulses; g. comparing the calculated ICP pressure augmentation index (PAIx) and flow augmentation index (FAIx) to measure (gender-specific) pressure and flow augmentation data indicative of a measured ICP to thereby estimate actual ICP; and h. noting any disparity between ED measured for pressure waves and ED measured for flow.

A method for measuring sound from vortices in the carotid artery comprising: first and second quality control provisions, wherein the quality control compares detected sounds to predetermined sounds, and upon confirmation of the quality control procedures, detecting sounds generated by the heart and sounds from vortices in the carotid artery for at least 30 seconds.

Systems and computer-implemented methods of automated physiological monitoring and prognosis of a plurality of subjects. A system includes a plurality of monitoring devices, each having a portion configured for deployment on a surface either opposite a concha or over a mastoid region of a subject, where real-time physiological parameter monitoring is performed. Each monitoring device also includes processor-executable program code configured to periodically generate respective values indicative of real-time physiological signs for the respective subject, and a transmitter configured to periodically and wirelessly transmit these periodically generated respective values to a mobile communication and display device. The mobile communication and display device is configured to use these periodically received respective values for the plurality of subjects from the plurality of monitoring devices to periodically generate a respective prognosis score for each subject, and to periodically generate an alert for at least two of the subjects.
