  • Publication number: 20180214648
    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.

  • Publication number: 20180216487
    Abstract: In one example embodiment, a fluid induced instability detection system is provided that monitors various vibration characteristics of a turbomachine, collects vibration data in real-time, and uses the vibration data to detect and analyze changes in various operating parameters such as vibration, speed, and loading conditions, and to provide an indication of a vibration anomaly and/or potential operational risk in one or more components of the turbomachine. The vibration data can be particularly associated with certain components that are directly or indirectly impacted by a modification in process fluid flow characteristics or lubrication oil flow characteristics in the turbomachine due to various reasons such as process fluid flow disturbances, lubricating oil flow disturbances, and/or a change in turbomachine operational parameters. The fluid induced instability detection system detects abnormalities in the vibration data and provides an indication of one or more potential faults in the turbomachine.
