  • Patent number: 10226200
    Abstract: A method for configuring a presentation of physiological data for a patient includes identifying one or more physiological sensor modules that are connected in a physiological parameter monitoring device. After the physiological sensor modules are identified, the physiological parameter monitoring device is configured so that display areas are allocated on a display screen of the physiological parameter monitoring device for displaying physiological data for the patient. A separate display area is allocated for each identified physiological module. After one or more physiological sensor modules are detected as being connected, the physiological parameter monitoring device is automatically configured to include one or more additional display areas on the display screen for displaying physiological data for the patient. A separate additional display area is allocated for each of the additional physiological sensor modules that is connected.

  • Publication number: 20190015048
    Abstract: A system for detecting one or more physical assessment parameters of a subject includes a sensing patch and a processor. The sensing patch is configured to sense signals from the subject corresponding to one or more physical assessment parameters, reduce sensed parameter data corresponding to the sensed signals, and transmit the sensed parameter data. The sensing patch also includes at least one adjustable sensing patch parameter. The processor is separate from the sensing patch and configured to receive the sensed parameter data from the sensing patch and transmit a command to the sensing patch. The sensing patch is configured to perform different amounts of data reduction on the sensed parameter data before transmitting the sensed parameter data to the processor. These different amounts of data reduction are determined at least in part by one or more system parameters.

  • Patent number: 10165984
    Abstract: A method of determining a value indicative of a hemodynamic parameter of a patient includes performing a plurality of value determinations. Performing the plurality of value determinations includes determining a first value indicative of the hemodynamic parameter, determining, with a controller, a difference between the first value and a baseline associated with the first value, and replacing the baseline with the first value, in a memory of the controller, if the difference is outside of a predetermined range. The method also includes determining an estimate of the hemodynamic parameter based on acceptable values determined during the plurality of value determinations.
