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 inflatable substance.

Aspects of the present disclosure provide methods, apparatuses, and systems for non-linear breathing entrainment. According to an aspect, a final breathing period is selected, and a current breathing period of a user is measured. A guiding stimulus configured to alter the current breathing period towards the final breathing period over an interval of time at a non-linear prescribed rate is output. A difference between the current breathing period and a target breathing period along the non-linear linear prescribed rate is determined. Based at least in part on the difference, the guiding stimulus and/or the non-linear prescribed rate are adjusted. The guiding stimulus and the non-linear prescribed rate may be stabilized, increased, or decreased to enable the user to reach the final breathing period.

A lung exercise measurement device and method that utilizes one or more lift timers, rest timers and/or set counters to accurately display valuable metrics and goals for tracking and improving respiratory development using a lung trainer breathing technique device, with particular advantages for instructive, competitive, self-learning, and group training environments.

A nasal breathing control apparatus has one or more axially extending cylinders having a first end, a second end, a mid-portion and an inner chamber having a first inner end and a second inner end and extending along a longitudinal axis together with a first opening in said first end connected to said inner chamber, a second opening in said second end, connected to said inner chamber and a float having a first end and a second end within the inner chamber and being movable between a first position in which it obturates said first opening and a second position in which it partially obturates the second opening; wherein each of the cylinders is tapered and wherein the cross-section of each of the cylinders comprises a width that decreases from said first end towards said second end of the cylinder.

A portable user device, method and computer program provide rhythmic athletic training assist by tracking an athletic proficiency level of a user. A respective sport control affordance for a plurality of sports are presented on a user interface of the portable user device. In response to a user selection of one sport control affordance associated with a selected sport, more than one drill control affordance for a type of athletic drill associated with the selected sport are presented on the user interface. In response to a user selection of a particular drill control affordance for a particular type of athletic drill, the type of athletic drill is associated with two or more available rhythmic speed settings. Based upon the tracked proficiency level of the user, one of the two or more rhythmic speed settings is selected. Video/audio guide is presented on the user interface at the selected rhythmic speed setting.

A musical instrument therapy device for providing strengthening therapy for sleep apnea treatment. Utilization of the device can help to strengthen the user's muscles of the throat and tongue, which can help the user to maintain an open airway during sleep (reduce airway collapse) and prevent airway blockages, thereby reducing the chance of obstructed breathing during sleep. The musical instrument therapy device comprises: a tubular body defining an air column; a mouthpiece located at a first end of the tubular body configured to receive a blow input; a mute located at a second end of the tubular body configured to mute the blow input; a plurality of sensors configured to obtain measurements associated with the blow input; a processing unit configured to make one or more determinations associated with blow input based on the obtained measurements; and an indicator configured to display an indication of the one or more determinations.

Aspects of the present disclosure provide methods, apparatuses, and systems for dynamic starting rates for guided breathing. According to an aspect, a user's initial breathing metric is determined. A multiplier is then determined, where the multiplier varies as a function of the initial breathing metric within a range. The level of intensity of the multiplier may vary, and may be a dynamic feature based on the determination of the user's initial breathing metric. Once the multiplier is determined, the multiplier is applied to the user's initial breathing metric to determine a starting breathing metric for guided breathing. The starting breathing metric is slower than or equal to the user's initial breathing metric.
