A system for respiration monitoring includes a garment, which is configured to be fitted snugly around a body of a human subject, and which includes, on at least a portion of the garment that fits around a thorax of the subject, a pattern of light and dark pigments having a high contrast at a near infrared wavelength. A camera head is configured to be mounted in proximity to a bed in which the subject is to be placed, and includes an image sensor and an infrared illumination source, which is configured to illuminate the bed with radiation at the near infrared wavelength, and is configured to transmit a video stream of images of the subject in the bed captured by the image sensor to a processor, which analyzes movement of the pattern in the images in order to detect a respiratory motion of the thorax.

The present invention provides, among other things, apparatus and methods of use for treating a subject in need of assistance with breathing. In some embodiments the subject suffers from airflow obstruction. In some embodiments, the subject suffers from chronic obstructive pulmonary disease.

There is provided a respiratory monitoring device (100) comprising one or more respiratory-related sensors (110) and a first circuit board comprising a controller. The one or more respiratory-related sensors are separated from and in communication the first circuit board. There is also provided a respiratory monitoring device comprising a controller, one or more respiratory-related sensor and an input means (114). The input means is arranged to trigger the controller to suspend sensing by at least one of the one or more respiratory-related sensors for one or more predetermined time periods. There is also provided a respiratory monitoring device having a housing comprising a front surface (102) at which one or more respiratory-related sensors are arranged, and a back surface (120), wherein the front surface is arranged to indicate an intended orientation to a user of the respiratory monitoring device.

Implementations illustrated herein discloses a method of controlling drug titration to a patient, the method including receiving, using a processor, a sequence of depth images, each depth image including depth information for at least a portion of the patient, determining, using the processor, a sequence of physiological signals for the patient based on the sequence of depth images, analyzing, using the processor, the sequence of physiological signals for the patient to determine a change in a condition of the patient, and generating a signal to a drug infusion pump in response to determining the change in the condition of the patient.

Apnea events may be detected based on a primary biomarker, e.g., respiration, in the one or more physiological signals. The apnea events may be characterized as one of an obstructive sleep apnea (OSA) event, a central sleep apnea (CSA) event, or a combination OSA/CSA event based on a secondary biomarker, e.g., a frequency spectrum or a morphology of the respirations in the one or more physiological signals. A first electrical stimulation may be provided to treat OSA in response to a first one or more of the apnea events being characterized as OSA events. A second electrical stimulation may be provided to treat CSA in response to a second one or more of apnea events being characterized as CSA events. A third electrical stimulation may be provided to treat combination OSA/CSA in response to a third one or more of the apnea events being characterized as combination OSA/CSA events.

The present invention relates to the field of medical monitoring, and, in particular, to non-contact detecting and monitoring of patient breathing. Systems, methods, and computer readable media are described for calculating a change in depth of a region of interest (ROI) on a patient and assigning one or more visual indicators to at least a portion of a graphic based on the calculated changes in depth and/or based on a tidal volume signal generated for the patient. In some embodiments, the systems, methods, and/or computer readable media can display the visual indicators overlaid onto at least the portion in real-time and/or can display the tidal volume signal in real-time. The systems, methods, and/or computer readable media can trigger an alert and/or an alarm when a breathing abnormality is detected.

The invention relates to a piece of sleeping or reclining furniture, comprising a support element (2) for applying a padding or a mattress and at least one sensor (12) for detecting vibrations, movement, and/or sound. The piece of sleeping or reclining furniture is characterized in that the at least one sensor (12) is arranged at a section (120) of the support element (2) that is decoupled from further sections of the support element (2) and/or of the sleeping or reclining furniture.

This disclosure relates generally to breathing analysis of a subject. Breathing analysis on a regular basis allows early detection for the onset of diseases, thus saving resources and cost in treatments. The existing state of art techniques require specialized devices to collect-infer the breathing and are mostly limited to analyzing breathing rate. The disclosure enables breathing analysis using a personal digital assistant (PDA). The breathing analysis includes (a) estimating exhale period-inhale period, (b) estimating the breathing rate and (c) determining the type of breathing. A PDA such as a smartphone is used receive accelerometer data from a subject. The received data is pre-processed in several steps including estimating a plurality of parameters, identifying a plurality of breathing cycles. The breathing cycles of the subject are further analyzed at real time based on the plurality of parameters to provide the breathing analysis of a subject.

A breathing sensing device that detects breathing of a subject, the breathing sensing device including a film-shaped sensor configured to adhere to a body surface of the subject from a region corresponding to a xiphoid process of a sternum of the subject to a region corresponding to an epigastrium of the subject. The sensor is configured to detect the breathing of the subject by detecting relative positional changes between the region corresponding to the xiphoid process and the region corresponding to the epigastrium.
