Problems solved by technology

If the position of the center point of the three-axis accelerometer changes due to whole-body movement (such as walking), however, this produces an additional inertial acceleration component in addition to the acceleration due to gravity

Embodiment Construction

[0051] figure 1 An embodiment of a respiration monitor 1 for measuring a respiration signal of a subject 100 is shown. The respiration monitor 1 is applied at a suitable location on the body of the subject 100 for measuring the respiration movement. Suitable locations include, but are not limited to, the chest and thoracic region, such as figure 1 depicted in . However, any part of the subject 100 that is affected by the breathing movement can be envisioned, in particular the upper body.

[0052] A respiration monitor 1 according to an aspect of the invention enables non-invasive measurements of respiration signals. Such as figure 1 As can be seen in , the respiration monitor 1 can be implemented as a small device that can be simply applied to the body of the subject 100 . Conventional respiratory monitoring equipment, such as nasal cannula, is inconvenient for the patient. Alternative conventional respiratory monitoring devices, such as for respiratory induction plethys...

Abstract

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.

Description

technical field [0001] The invention relates to a processing device and a processing method for determining a breathing signal of a subject. Background technique [0002] Respiratory rate has been shown to be a good indicator of the deterioration of the patient's condition. In combination with other vital signs, respiratory rate plays an important role in the early warning system. Therefore, there is a need for continuous and reliable monitoring of the respiratory signal, from which the respiratory rate is extracted, in an intensive care unit of a hospital. Similar needs exist in the general ward environment of a hospital as well as in home health care applications, such as in telemedicine and chronic disease management. [0003] Although continuous monitoring of respiratory signals is available at the bedside for intensive care patients, a variety of portable sensor systems are being developed to allow monitoring of respiratory signals in general wards and home healthcare...
