Systems, devices, and methods for determining a user's lung capacity may employ a sound-producing breathing device and a recording device such as a microphone included in a user electronic device (e.g., smart phone or tablet computer). A user may inhale or exhale through the sound-producing breathing device, thereby producing a sound that is received by the microphone and communicated to a processor. The processor may analyze the received sound recording to determine one or more sound intensity values over, for example, the duration of the received sound and/or points in time within the sound recording. The sound intensity values may then be used to determine the user's lung capacity.

A wearable device and system has been developed to help users learn the practices of diaphragmatic breathing and breathing patterns to improve running and walking performance. The wearable has a breathing sensor (breathe in-breathe out) and a movement sensor used to identify foot strikes. A processor computes the number of foot strikes occurring while inhaling and the number of foot strikes occurring while exhaling to report breathing patterns as a function of time. The algorithms may be modified to teach breathing patterns to athletes in other sports and deep breathing for numerous movement and minimal movement applications.

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.

A method of and device for acquiring in-vivo images or quantitative/qualitative data (perfusion, blood flow, vascularization, contrast enhancement, selective blood supply management) of interior parts of the human body (20) is described, using an imaging system (21) and including the steps of positioning the body (20) relatively to the imaging system (21), applying a respiratory resistance device (10) to the respiratory system of the body (20), and performing an image acquisition step during or concomitantly an inhalation/inspiration/suction or exhalation/Valsalva/expiration phase, during which the body provides suction or exhalation against a resistance as provided by the respiratory resistance device (10).

An exercise with oxygen therapy (EWOT) apparatus for rejuvenating oxygen-depleted cell tissue and simulating high altitude oxygen conditions. The EWOT apparatus includes a first cylindrical bladder for providing oxygen-enriched air and a second bladder for providing lower-purity hypoxic air. The first bladder is retained within an open, lightweight rectangular-shaped frame having vertical frame members. An air supply source provides the oxygen-enriched and hypoxic air to the first and second bladders, respectively. A control switch, which can be manually and/or programmed to automatically operate, selectively delivers the oxygen-enriched and/or hypoxic air to a breathing mask worn by a user while exercising on exercise equipment. The first bladder includes a plurality of weights which provide a positive pressure to the air therein. The cylindrical first bladder is attached to the vertical frame members with slidable rings and expands and collapses in a vertical direction when being filled or during use, respectively.

A respiratory training device providing both inspiratory and expiratory functional evaluation and training, as well as independent regulation of both the inspiratory and expiratory airway resistance levels used during training. The respiratory training device also includes data acquisition, recording, storage, retrieval and display functions for airway pressure monitoring data to provide functional evaluation, physiological monitoring, and diagnostic features. The respiratory training device allows the user to easily develop and follow precise and advanced training protocols, and utilize the respiratory device in both the clinical and home setting.

A training mask for the training of the respiratory muscles and/or snorkeling mask with improved air routing of the inhaled and/or exhaled air includes a half mask (8) sealingly closing the mouth and nose area, wherein an air-conducting channel connector (15, 40) with hollow profile is arranged in front of the half mask (8), via which connector at least the inhaled air can be introduced frontally in the half mask (8) via an approximately central inflow opening (22).

Systems and methods directed to handheld respiratory diagnostics, trainings, and therapy are disclosed. More specifically, a device that collects data associated with a user's breathing using sensors, analyzes that data to determine time series readings of one or more health-related vitals, and generates trainings and therapies to assist the user in real time is described.
