  • Patent number: 10286169
    Abstract: A method of controlling a ventilator to provide spontaneous breathing support includes determining a target CO2 value, determining a support pressure, detecting a patient-generated spontaneous breath, and delivering ventilation gas to the patient based on the support pressure. A patient CO2 is then measured, along with measuring at least one of a patient breath rate and a breath volume. The patient CO2 is compared to the target CO2 value. The patient's respiratory drive is determined based on at least one of the patient breath rate and the breath volume. If elevated respiratory drive is detected, then the support pressure is adjusted accordingly. If elevated respiratory drive is not detected, then the target CO2 value is adjusted based on the measured patient CO2.

    Abstract: A medical device system includes a first patient monitor having a proximity beacon that communicates compatibility information and a medical device associated with the same patient as the first patient monitor. The medical device includes a device proximity detector that detects a proximity beacon when the first patient monitor is within a predetermined proximity range of the medical device, and a device workflow module executable on a processor to receive compatibility information and determine whether the first patient monitor is a compatible device. If so, then a direct communication channel is established with the first patient monitor and a device workflow is identified that corresponds with a monitor workflow executable by the first patient monitor. The medical device then communicates with the first patient monitor via the direct communication channel to execute the identified device workflow until a termination condition is reached.

  • Patent number: 10291029
    Abstract: The technology is generally directed towards real-time power grid island detection and monitoring, including obtaining and outputting information about the cause and location of the islanding event, island size, island composition, phasor measurement units in each island, and the overall island frequency. The technology provides for suggested island resynchronization actions such as one or more circuit breakers that can be closed by the power grid system operators to resynchronize an island with the main island/system. An application program may output the information and also assist the operators during the resynchronization process by providing real time information about the voltage difference and frequency difference across each proposed circuit breaker in the suggested restoration point. Real-time tracking of the island resynchronization actions is also described.
