  • Patent number: 10998095
    Abstract: Disclosed herein are approaches for monitoring a patient in real-time for ARDS development and providing a biomarker-driven ventilation therapy recommendation tool based on the correlation of various therapy patterns and an ARDS biomarker score. When the ARDS biomarker indicates that a patient has a high ARDS risk, the recommendation tool suggests possible therapy routes based on clinical practice. In response to a high score output by the ARDS detection model, the tool outputs a recommendation to initiate a lung protective ventilation strategy (Low Tidal Volume, high Positive End-Expiratory Pressure (PEEP)). A high ARDS score is recognized to be predictive of the appropriateness of such therapy up to several hours before such intervention is typically initiated under current clinical practices.

  • Patent number: 10983945
    Abstract: Methods, devices, and computer programs are presented for consolidating overlapping data provided by multiple sources. One method includes operations for associating a plurality of devices to a user, each device operable to capture data associated with the user, and for receiving, from the plurality of devices, captured data about a first activity associated with a first period of time. Additionally, the method includes operations for detecting that the received captured data from two or more devices provide overlapping information about the first activity, and for evaluating one or more rules for consolidating the overlapping information to produce consolidated data. The consolidated data provides a unified view of the first activity during the first period of time. The consolidated data is stored in permanent storage and made available for presentation to the user.

  • Patent number: 10957335
    Abstract: An acoustic sensor is positioned in an environment and configured to generate a data stream responsive to acoustic energy in the environment. A controller is configured to receive the data stream. The controller is further configured to analyze the data stream to determine ambient acoustic signals. The controller is further configured to generate an ambient acoustic template based on the determined ambient acoustic signals. The controller is further configured to apply the ambient acoustic template to the data stream so that the ambient acoustic signals are suppressed in the data stream. The controller is further configured to analyze the data stream after the ambient acoustic signals are suppressed in order to determine if the acoustic energy in the environment includes acoustic energy of human snoring. The controller is further configured to issue a control signal to a second controller in order to engage a home automation device.

  • Patent number: 10925514
    Abstract: A CO2 monitoring system provides oxygen (O2) to a subject's mask with known characteristics. The CO2 monitoring system receives, from the mask, gas samples including exhaled CO2 diluted by O2. The CO2 monitoring system uses an adaptive noise canceller to cancel the diluting O2 by using the known characteristics of the O2 provided to the mask, the result of which process is restoration of the original concentration level of the CO2 as exhaled by the subject into the mask.

  • Patent number: 10918309
    Abstract: For COPD assessment in medical imaging, imaging data is used to model airways and to extract values for features representative of COPD. The airway model provides values for anatomy of the airways and/or airflow. The values of anatomy, airflow, and/or extracted image features in combination indicate COPD information A machine-learned model may be used to relate the anatomy, airflow, and/or extracted image features to the COPD information. Additional information may be used, such as spirometry results and/or questionnaire answers. The combination of information, including airway modeling, as input to a COPD model may provide a more comprehensive understanding of COPD for assistance in therapy and/or diagnosis of a particular patient.

  • Patent number: 10874358
    Abstract: A method for detecting the need for providing assistance to an individual suspected of overdosing on an opiate is provided. The method includes using a wearable device for continuous or intermittent monitoring of one or more physiological parameters of the individual. If the level of one of the one or more physiological parameters exceeds a threshold level specific to that parameter, an alarm is triggered. If the alarm is not aborted, an alert is transmitted to one or more emergency contacts conveying that the individual has overdosed. The method optionally provides for injection of an opioid receptor antagonist into the individual to reverse the effects of the overdose. Also provided is a device for implementing these methods.

    Abstract: Automated devices provide methodologies for determining sleep conditions, which may be in conjunction with treatment of sleep disordered breathing by a pressure treatment apparatus such as a continuous positive airway pressure device. Based on a measure of respiratory airflow, respiratory characteristics are extracted to detect arousal conditions, sleep stability, sleep states and/or perform sleep quality assessments. The methodologies may be implemented for data analysis by a specific purpose computer, a monitoring device that measures a respiratory airflow and/or a respiratory treatment apparatus that provides a respiratory treatment regime based on the detected conditions.
