  • Publication number: 20230200679
    Abstract: 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.

  • Publication number: 20230196797
    Abstract: System and methods for non-contact monitoring in vehicles are described. The systems and methods may use depth sensing cameras as part of the non-contact monitoring system. In some embodiments, depth data from at least one depth sensing device that has a field of view of at least part of the interior of the vehicle is received, wherein the depth data represents depth information as a function of position across the field of view. The depth data is then processed to obtain further information related to the occupant within the vehicle.

  • Publication number: 20230111386
    Abstract: The present invention relates to the field of medical monitoring, and in particular non-contact monitoring of one or more physiological parameters in a region of a patient during surgery. Systems, methods, and computer readable media are described for generating a pulsation field and/or a pulsation strength field of a region of interest (ROI) in a patient across a field of view of an image capture device, such as a video camera. The pulsation field and/or the pulsation strength field can be generated from changes in light intensities and/or colors of pixels in a video sequence captured by the image capture device. The pulsation field and/or the pulsation strength field can be combined with indocyanine green (ICG) information regarding ICG dye injected into the patient to identify sites where blood flow has decreased and/or ceased and that are at risk of hypoxia.

  • Publication number: 20230094301
    Abstract: An example device for determining one or more transient decelerations includes a memory configured to store a sensed pulse rate signal indicative of one or more sensed pulse rates and processing circuitry. The processing circuitry is configured to determine that an amplitude threshold is crossed by a sensed pulse rate signal indicative of one or more sensed pulse rates. The processing circuitry also is configured to, from a time the amplitude threshold is crossed, determine that a pulse rate returns to within a range of a baseline pulse rate within a number of samples or a time period. The processing circuitry is also configured to, based on the pulse rate returning to within the range of the baseline pulse rate, from the time the amplitude threshold is crossed, within the number of samples or the time period, determine a transient deceleration.

  • Publication number: 20230095345
    Abstract: System and methods for video-based neonatal patient monitoring are described. Methods for neonatal patient monitoring can generally include use of a non-contact detector, such as a depth-sensing camera, to obtain data pertaining to the neonate that can then be used to calculate or otherwise determine a neonate patient breathing parameter, such as respiratory volume. The method further includes monitoring the breathing parameter to identify the occurrence of a neonate breathing event, such as apnea, and initiating a neonate stimulation event when a breathing event is identified. The stimulation event can include, e.g., vibration, auditory signals, visual signals, and/or other types of tactile signals. The systems and methods can use additional monitoring apparatus to monitor additional neonate health parameters, and incorporate this additional information into the decision of when a stimulation event should be initiated.
