Devices, systems, and methods for non-invasively detecting and monitoring medical conditions using multiple modalities of sensing include at least two electrodes configured to be positioned on a subject, an acoustic sensor configured to be positioned on a subject, a thoracic impedance measurement module connected to the electrodes, for measuring a first impedance between the electrodes, and a heart acoustic measurement module connected to the acoustic sensor, for detecting and measuring a heart sound from the acoustic sensor.

A sleep apnea and obesity comorbidity treatment system includes a transceiver and a control module. The control module is configured to: receive sensor data, where the sensor data is indicative of a glucose level of a patient and a ketones level of the patient, transmit the sensor data to a remote feedback device, receive feedback information from the remote feedback device based on the sensor data, and where the feedback information provides indications to the patient to maintain or alter a behavior of the patient based on the glucose level and the ketones level, and based on the feedback information, performing an operation to maintain or alter at least one of a diet or physical activity of the patient.

The present invention relates to a sleep apnea monitoring system for monitoring the sleeping state of a user by means of impedance tomographic image information about the properties of biological tissue and biological signals of the user's body parts to be monitored. The present invention can be manufactured into a very simple portable device and thus enables monitoring during natural sleep at home. Therefore, the present invention enables utilization of obtained information during a sleeping state for diagnosis of and therapeutic plans for sleep apnea.

Systems and methods for novel ventilation that allows the ventilator to detect a patient intention to cycle exhalation are provided. Further, systems and methods for cycling exhalation based on a muscle pressure are provided.

The present disclosure describes an ultrasound imaging system configured to identify a target placement of an ultrasound probe for viewing a lung pleural line. In some examples, the system may include an ultrasound probe configured to receive ultrasound echoes from a subject to image a region of the subject and a data processor in communication with the ultrasound probe. The data processor may be configured to identify one or more candidate pleural lines and one or more A-lines corresponding to the candidate pleural lines, compute an A-line intensity of at least one of the A-lines, and apply the computed A-line intensity to indicate a target placement of the ultrasound probe for imaging the region for pleural line identification. The system may also include a user interface in communication with the data processor. The user interface may be configured to alert the user of the target placement of the ultrasound probe.

Epidermal electronics are non-invasive and non-obstructive skin mounted sensors with mechanical properties matching human epidermis. Their manufacturing process includes photolithography and dry and wet etching within cleanroom facilities. The high cost of manpower, materials, photo masks, and facilities greatly hinders the commercialization potential of disposable epidermal electronics. In contrast, an embodiment of the invention includes a low cost, high throughput, bench top “cut-and-paste” method to complete the freeform manufacture of epidermal sensor system (ESS) in minutes. This versatile method works for many types of thin metal and polymeric sheets and is compatible with many tattoo adhesives or medical tapes. The resultant ESS is highly multimaterial and multifunctional and may measure ECG, EMG, skin temperature, skin hydration, as well as respiratory rate. Also, a stretchable planar coil made of serpentine ribbons can be used as a wireless strain gauge and/or a near field communication (NFC) antenna. Other embodiments are described herein.

A method and apparatus for the treatment of Sleep Apnea events and Hypopnea episodes wherein one embodiment comprises a wearable, belt like apparatus containing a microphone and a plethysmograph. The microphone and plethysmograph generate signals that are representative of physiological aspects of respiration, and the signals are transferred to an imbedded computer. The embedded computer extracts the sound of breathing and the sound of the heart beat by Digital Signal Processing techniques. The embedded computer has elements for determining when respiration parameters falls out of defined boundaries for said respiration parameters. This exemplary method provides real-time detection of the onset of a Sleep Apnea event or Hypopnea episode and supplies stimulation signals upon the determination of a Sleep Apnea event or Hypopnea episode to initiate an inhalation. In one embodiment, the stimulus is applied to the patient by a cutaneous rumble effects actuator and/or audio effects broadcasting.
