Disclosed herein are embodiments of an athletic coaching system that includes at least one inward-facing head-mounted thermal camera (CAM) and a computer. Each CAM from among the at least one CAM is configured to take thermal measurements of a region below the nostrils (denoted TH.sub.RBN) of a user. TH.sub.RBN are indicative of an exhale stream of the user (e.g., an exhale stream from a nostril and/or from the mouth). The computer is configured to: receive measurements of movements (M.sub.move) involving the user; generate, based on TH.sub.RBN and M.sub.move, a coaching indication; and present, via a user interface, the coaching indication to the user. In one example, the coaching indication is indicative of a change the user should make to one or more of the following: cadence of movements, stride length, breathing rate, breathing type (mouth or nasal), and duration of exhales.

A spirometry system includes an imaging device configured to capture upper body movement images of a subject during inhalation and exhalation of the subject. The system further includes at least one controller configured to receive the captured images from the imaging device and, based upon the received images, determine at least one of an image-based spirometry flow-volume curve for the subject or an image-based spirometry parameter for the subject.

A nasal cannula interface is provided for supplying a gases flow to a patient comprising: a nasal cannula defining at least a portion of a gases flow path and comprising a body having a base portion and at least one prong extending from the base portion, the at least one prong being configured to direct the gases flow to an orifice of the patient, and one or more sensors configured to measure a parameter. The one or more sensors may comprise a pulse oximeter. The one or more sensors may be mounted on the nasal cannula body, or headgear to which the body is connector. The one or more sensors may be configured to be in contact with the face of the patient, and may be configured to be mounted in and/or substantially flush with, a cheek contacting portion of the interface.

Methods and systems estimate cardio-respiratory parameter(s), such as from in-phase and quadrature channels. The channels may represent patient chest movement and may be generated with a sensor, such as a contactless sensor that may sense movement with radio-frequency signals. In the methods/systems, the in-phase and quadrature channels may be processed, such as in a processor(s), using relative demodulation to generate cardio-respiratory parameter estimate(s). Optionally, the processing produces a jerk signal that may be filtered for producing a heart rate estimate, such as from zero-crossings of the filtered signal. Optionally, the processing produces a chest velocity signal that may be filtered for producing a respiratory rate estimate, such as from zero-crossings of the filtered signal. Optionally, a respiratory volume, such as tidal volume, may be estimated from an intrapulmonary pressure signal generated by applying a function to a chest displacement signal where the function relates intrapulmonary pressure and chest displacement.

A medication delivery system including a holding chamber having an input and an output end, a backpiece coupled to the input end of the holding chamber and having an electrical circuit and an opening. An MDI includes an insert portion moveable between an engaged position wherein the insert portion is received in the opening and a disengaged position wherein the insert portion is removed from the opening, and at least one contact that completes the electrical circuit when the insert portion is in the engaged position.

A system for dynamic registration of autonomy using augmented reality can include an augmented reality system, an imaging system, a measuring system, and a computer system. The augmented reality system can be configured to display an augmented representation. The imaging system can be configured to image an anatomical feature of the patient and can generate anatomical imaging data. The measuring system can be configured to measure an anatomical movement of the patient and can generate an anatomical movement data. The computer system can be configured to receive the anatomical imaging and positional data and the anatomical movement data, generate the augmented representation based on the anatomical imaging data, associate the augmented representation with the anatomical movement data, render the augmented representation on the augmented reality system, and selectively update the augmented representation based on the anatomical movement data.

An airway adaptor includes: a nasal expiration collecting portion which is to be connected to a nostril of a living body, and which collects an expiration of the nasal cavity; a gas passage portion that forms a gas passage through which the expiration collected by the nasal expiration collecting portion passes; and a gas sensor attaching portion to which a gas sensor that is disposed in the gas passage portion, and that measures the concentration of a predetermined gas component contained in the expiration is attachable. The nasal expiration collecting portion shows a flowing state where a flow of the expiration is allowed, and an obstruction state where the flow of the expiration is blocked.

A breath analysis device into which a user exhales a breath sample is capable of venting an initial portion of the breath sample from the device, and routing a second portion of the breath sample into a disposable cartridge containing an interactant. The device may include a sensor, such as a pressure sensor, for detecting the initiation of exhalation, and may include a controller that switches a valve during the exhalation process to route a desired portion of the breath sample into the cartridge. After the exhalation process, an LED/photodiode arrangement, or another type of optical sensor, may be used to measure a color change produced by a chemical reaction in the cartridge, to thereby measure a concentration of a ketone or other analyte in the breath sample.

The present invention relates to a device (10, 10a, 10b), system (1, 2, 3) and method for detection of an asthma attack or asthma of a subject. For this purpose, the device comprises a light sensor input (11), e.g. a 2D camera, for obtaining light sensor data of the scene and a thermal sensor input (12), e.g. a thermal camera, for obtaining thermal sensor data of a scene including a subject while breathing. An analysis unit (13) obtains these data and derives respiratory effort information indicating respiratory efforts of the subject from the obtained light sensor data and/or the obtained thermal sensor data and derives airflow information indicating airflow during respiration of the subject from the obtained thermal sensor data. Further, the analysis unit (13) predicts or detects an asthma attack or asthma based on analysis of the respiratory effort information and the airflow information, said analysis evaluating deviations from predetermined or healthy correlations between respiratory efforts and airflow.

A spiroergometry apparatus for detecting parameters of a respiratory gas. The spiroergometry apparatus has a main body, a measuring device, a computing unit and an energy store. The measuring device includes a sensor, which is provided on the main body, whereby it becomes possible to detect parameters directly in the respiratory gas flow, so that an in-situ detection of the parameters of the respiratory gas is made possible.
