  • Patent number: 9981097
    Abstract: Described are systems and methods for compensating long term sensitivity drift of catalytic type electrochemical gas sensors used in systems for delivering therapeutic nitric oxide (NO) gas to a patient by compensating for drift that may be specific to the sensors atypical use in systems for delivering therapeutic nitric oxide gas to a patient. The long term sensitivity drift of catalytic type electrochemical gas sensors may be addressed using calibration schedules, which can factor in the absolute change in set dose of NO being delivered to the patient that can drive one or more baseline calibrations. The calibration schedules can be used to reduce the amount of times the sensor goes offline.

  • Patent number: 9962509
    Abstract: A device and process generates an alarm during a machine-assisted ventilation of a patient. A minute volume is measured and a median of the minute volume and a lower critical limit value of the minute volume and a time delay are determined and are recorded in a control device. A reference signal is determined as a function of the lower critical limit value for the minute volume and the time delay based on the median of the minute volume. From the reference signal an alarm limit value located below the lower critical limit value as well as a value for a maximum tolerated duration of apnea of the patient are derivable. An alarm signal is generated both during an undershooting of the lower critical limit value over a period of time that is longer than the established time delay and during an undershooting of the alarm limit value.

  • Patent number: 9956361
    Abstract: A device outputs portioned medications (M) from individual chambers of a strip arranged one behind the other. The strip includes a base strip and a closure strip and the raised chambers of the strip can be opened by pressing a handle by sharp-edged deflection of the closure strip. In order to simplify the design and for safe operation, a chamber elevation directed toward the mouthpiece opening blocks the actuation of the handle using a blocking element, in which position a chamber arranged in front that has already been freed from the closure strip lies above a fall-through opening, which opening is closed using a flap that can be moved into the opening position by the suction air flow.

  • Patent number: 9956363
    Abstract: Various embodiments of the present disclosure provide systems, methods and devices for respiratory support. As one example, a method for respiratory support is described that includes providing a measured pressure, and calculating a net flow based on at least one measured inlet flow and measured outlet flow. A relationship between a first value related to the measured pressure, a second value related to the measured net flow and a third value related to patient effort is used to provide a prediction of patient effort. An interim value is updated based at least in part on the prediction of the patient effort, and used to help compute a patient effort. A ventilation cycle is initiated using the computed patient effort.
