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 and system for indicating a breathing pattern is disclosed. The system comprises a plurality of smart wearable devices, a plurality of mobile devices, an application server and a database. The plurality of smart wearable devices is either connected to the mobile devices or directly connected to the application server. The database is connected to the application server to store the data transmitted by the smart wearable device or the mobile device. The plurality of smart wearable devices is capable of monitoring the health index and identifying the variation in health conditions of the user, in real-time and activating a suitable breathing pattern to normalize such medical condition.

The present disclosure relates a method, device, electronic apparatus, and system of providing information for breathing training, and storage medium. The method of providing information for breathing training includes receiving first data input on a first display interface, the first data including breathing training time data; and presenting output data on a second display interface, the output data including breathing beat image prompting an exhaling action and an inhaling action by using alternate graphics.

The present disclosure relates to a respiratory system for exercising and analysing respiration of a subject comprising: a breathing unit comprising: a mouthpiece connected to: at least one inhalation air way, at least one exhalation air way, and an electronic sensor unit comprising at least one pressure gauge for measuring air pressure in the mouthpiece, and a processing unit for collecting/storing and/or transmitting air pressure data.

Aspects of the present disclosure provide methods, apparatuses, and systems for non-linear breathing entrainment. As described herein, “breathing entrainment” refers to guiding a user's breath or breathing. According to an aspect, an initial breathing period and a final breathing period are selected. Based on the initial and final breathing periods, a non-linear breath rate per minute sequence is determined. A guiding stimulus is output and aligned with the non-linear breath rate per minute sequence. The guiding stimulus is non-linearly altered with the non-linear breath rate per minute sequence to align with the final breathing period over an interval of time. The non-linear alterations of the guiding stimulus vary based on an amount of time the guiding stimulus has been output.

A system and method are configured to adjust the tidal volume of the breathing of a subject. The subject is self-ventilating (breathes under her own power). The adjustment of tidal volume accomplished through use of the system and/or method may reduce hypertension (e.g., lower blood pressure), reduce stress and/or anxiety (and related maladies), improve relaxation, decrease sleep latency, improve sleep quality, address other sleep disorders, and/or provide other health benefits. The system and method are effective in adjusting tidal volume while the subject is awake and/or asleep.

Various example embodiments relate to a respiration guidance device including: an outer casing configured to change shape; and a drive unit located within the outer casing and configured to change the shape of the outer casing according to a desired breathing pattern; and the outer casing has at least one slit dividing the outer casing into at least one portion displaceable with respect to a remaining portion of the outer casing; and the drive unit is configured to change the shape of the outer casing by displacing the at least one portion.

A device for facilitating or enhancing proprioceptive feedback during breathing and related exercises includes a user attachment component attachable to a user about the thorax. Two elongate tensile members are connected at proximal ends to the user attachment component at points essentially just below the armpits of a user. These two elongate tensile members are connectable at their distal ends to the feet of the user. Another two tensile members are connected at their proximal ends to a back portion or strap of the harness and at their distal ends to or about the user's hands.

Aspects of the present disclosure provide methods, apparatuses, and systems for dynamically adjusting a breathing entrainment based on whether a user is stressing or relaxing. According to an aspect, a first target breathing period is selected, and a guiding stimulus configured to alter a current breathing period of the user towards the first target breathing period over an interval of time is output. One or more relaxation biometrics are measured and analyzed to determine whether the user is stressing or relaxing. Based on whether the user is relaxing or stressing, at least one of the guided stimulus and the first target breathing period are adjusted, where the first target breathing period is adjusted to a second target breathing period different from the first target breathing period. By making adjustments based on whether a user is relaxing or stressing, the breathing entrainment is more effective and comfortable for users.

An oscillating positive expiratory pressure system including an oscillating positive expiratory pressure device, an adapter coupled to the device, and a control module coupled to the adapter. The control module provides real time information about the use of the device, and provides feedback and storage of the information to improve the use thereof.
