The invention provides a respiration monitoring device, a respiration monitoring system, a medical treating system, a respiration monitoring method, and a respiration monitoring program. The respiration monitoring device comprises an image acquiring section for so acquiring an image that an imaging object region including a body portion of a subject reciprocally moving as the subject respires is inclined at a predetermined angle to the direction in which the body portion reciprocally moves at each predetermined timing, a variation computing section for computing the variation of the position of the imaging object region from a first time which is a given timing to a second time which is a timing coming after a predetermined number of timings from the first time according to the difference between the luminance of the pixels of the image acquired at the first time and that at the second time, and a position judging section for judging, as the position of the imaging object region at the second time, the position determined by adding the variation of the position of the imaging object region between the first and second times to the position of the imaging object region at the first time.

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.

An impedance variation respiration monitor determines the variation in human body impedance between two electrodes coupled to the surface of the body. One of the two electrodes is attached to the thorax below the armpit and the other of the two electrodes is attached to the leg extending from the opposing side of the thorax. The variation in impedance between these two electrodes measured by the monitor is closely correlated to the respiration rate of the subject and is particularly responsive to and indicates combined abdominal and thoracic breathing.

Ultra wideband radar motion sensors strategically placed in an area of interest communicate with a wireless ad hoc network to provide remote area surveillance. Swept range impulse radar and a heart and respiration monitor combined with the motion sensor further improves discrimination.

A monitoring device having a capnography capability employs a ventilation monitoring controller including a capnography monitor (20) and a respiration monitor (21) for determining between a non- hyperventilating ventilation being applied to a patient and a hyperventilating ventilation being applied to the patient. In operation, the capnography monitor (20) analyzes a capnography waveform of the patient. The respiration monitor (21) determines the non- hyperventilating ventilation being applied to the patient based on an indication by an end-tidal carbon dioxide expired by the patient and / or arespiratory rate of the patient derived, partially or entirely, from the analysis of the capnography waveform by the capnography monitor (20), and determines the hyperventilating ventilation being applied to the patient based on a collective indication by both the end-tidal carbon dioxide expired by the patient and the respiratory rate of the patient derived, partially or entirely, from the analysis of the capnography waveform by the capnography monitor (20).

A capacitive pressure sensor includes first and second of mutually displaceable elastic members (100, 150) each having a respective electrically conductive surface separated by a thin elastic dielectric. Variations in area of pressure-induced contact between the first and second members are used to vary capacitance of the sensor that allows determination of differential pressure between the two elastic members. Both of the elastic members have respective projections, the projections of the first elastic member being disposed in interlocking relationship with the projections of the second elastic member and configured so that as the elastic members are pressed toward each other their respective projections progressively engage and create increasing areas of contact.
