Wearable devices configured for facilitating diagnosis and/or assessment of pulmonary diseases, and corresponding methods

Exemplary implementations may provide objective, continuous, and clinically useful assessment of asthma control in subjects including young children using a device that is compact, non-intrusive, and simple. The device may include a water-resistant, flexible patch that can be comfortably worn for two weeks or more. In some implementations, the patch may resemble a Band-Aid that is placed on the supra-sternal notch. The device may record respiratory sounds that can be analyzed to identify coughing and wheezing episodes. The device may operate in different modes including ones for assessment of nocturnal symptoms, exercise-induced asthma, and overall asthma control. The device may be useful for objectively assessing asthma control to aid clinical therapy, and for an improved way to diagnose exercise-induced asthma.

Processing apparatus and processing method for determining a respiratory signal of a subject

A processing apparatus (6) for determining a respiration signal (34) of a subject (100) is presented. The processing apparatus (6) is configured to perform the steps of obtaining a movement signal (22) descriptive of a respiratory movement, determining a first quantity (24) descriptive of a rotation axis and/or rotation angle based on the obtained movement signal (22), and estimating a rotation axis (25) and/or rotation angle (26) based on the first quantity (24) and a rotation model, wherein the rotation model models the respiratory movement as a rotation around a single rotation axis. This model of the rotation can be further used as a feature for an instantaneous classifier descriptive of a movement artifact descriptive of a non-respiratory movement. Furthermore, a processing method, a respiration monitor (1, 91), a computer-readable non-transitory storage medium and a computer program are presented.
