A method of monitoring respiration with an acoustic measurement device, the acoustic measurement device having a sound transducer, the sound transducer configured to measure sound associated with airflow through a mammalian trachea, the method includes correlating the measured sound into a measurement of tidal volume and generating at least one from the group consisting of an alert and an alarm if the measured tidal volume falls outside of a predetermined range.

The present invention relates to the field of medical monitoring, and in particular non-contact video monitoring to measure tidal volume of a patient. Systems, methods, and computer readable media are described for determining a region of interest of a patient and monitoring that region of interest to determine tidal volume of the patient. This may be accomplished using a depth sensing camera to monitor a patient and determine how their chest and/or other body parts are moving as the patient breathes. This sensing of movement can be used to determine the tidal volume measurement.

The present disclosure discloses a method, device, apparatus, and storage medium for sleep monitoring. The method includes: monitoring physical sign information of a user in response to receiving a monitoring command; determining sleep quality information of the user according to the physical sign information of the user, wherein the physical sign information comprises at least breathing information.

A system for visualizing movement of structures within a patient's chest is described herein. The system includes an electromagnetic tracking system, a computing device and a display. The computing device includes a processor configured generate a 3D model of an interior of the patient, obtain positions of EM sensors for the 3D model, determine positions of the EM sensors at intervals during the respiratory cycle, determine positions of the EM sensors at maximum tidal volume and minimum tidal volume, determine differences between the positions of the EM sensors at maximum tidal volume and for the 3D model, generate a 3D model at maximum tidal volume based on the differences between the positions of the EM sensors at maximum tidal volume and for the 3D model, and store in memory the 3D model at maximum tidal volume.

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.

A detector (210) for indicating bodily functions of a person in the surroundings of the detector (210) is proposed. The detector (210) comprises a support structure and a Continuous-Wave (CW) radar module (214) supported by the support structure. The radar module (214) is configured to emit microwaves and receive microwaves that have been reflected in the surroundings of the detector (210), wherein the radar module (214) is configured to determine data indicating bodily functions from microwaves reflected on a person. The detector (210) further comprises a collimator (216) supported by the support structure and configured for collimating the emitted microwaves in one spatial direction, or towards a plane.
