An oscillatory PEP therapy device (100) has valve (10) mounted at the end of a rocker arm (12) such that the valve is opened and closed during expiration through the device, thereby causing displacement of the rocker arm up and down. The housing (2) of the device (100) is transparent so that the camera (20) on a mobile phone (200) can be positioned to view displacement of the rocker arm (12) during use. The phone (200) is programmed to extract a signal indicative of the frequency of oscillation of the rocker arm (12) and this is displayed on the screen of the phone to provide feedback to the user.

An obstructive sleep apnea detection device including an optical engagement surface adapted to engage a user's skin; a light source adapted to emit light from the optical engagement surface; a photodetector adapted to detect light at the optical engagement surface and to generate a detected light signal; a position sensor adapted to determine patient sleeping position; a controller adapted to determine and record in memory blood oxygen saturation values computed from the detected light signal and user position information from the position sensor; and a housing supporting the optical engagement surface, the photodetector, the light source, the position sensor, and the controller.

Methods and systems are described to obtain and analyze one or more gas samples from the breath of a person, and organizing the samples in a sample registry for subsequent analysis. This technique solves the various problems that are associated with targeting an individual breath for analysis, and allows for additional versatility and options in the analysis process.

Camera-based respiratory triggered medical scanning is provided. A camara captures an image or images of a patient. A processor detects breathing from the camera image or images. Detected breathing is used to automatically trigger the medical scan. An extra breathing sensor is not needed. Manual monitoring is not relied upon.

Disclosed are biofeedback methods and devices suitable for providing biofeedback useful for helping a user control an own breathing, for example, to help in inducing deep breathing, and such biofeedback devices further comprising a dispenser for dispensing an inhalable substance.

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 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.

Described herein are various embodiments of an informative display that may be used in conjunction with non-contact patient monitoring systems and methods. The informative display may include one or more patient data images providing historical and real time data relating the patient being monitored by the non-contact patient monitoring system. The patient data images may be configured to display visualizations of various patient events, such as low flow, apnea, and/or patient movement.

A gas measurement adapter includes a flow tube portion configured to allow gas to pass through the flow tube portion and a window portion configured to allow measurement light for measuring a component of the gas passing through the flow tube portion to pass through the window portion. The adapter is prepared by using an adapter forming material containing a cycloolefin-based resin as a main component.

Detecting abnormalities in vital signs of subjects of videos is provided. Aspects of the present disclosure include methods, apparatuses, and systems to detect and measure vital sign information of one or more human subjects of a video and detect abnormalities in the vital sign information. In some examples, such abnormalities can be used to indicate video data is likely altered or fraudulent. In this regard, imaging photophlethysmography (IPPG) and advanced signal processing techniques, including adaptive color beamforming, can be used to extract the vital signs of the video subjects.
