  • Patent number: 11154673
    Abstract: A ventilation system includes a breathing apparatus which provides a mechanical ventilation to a patient. The breathing apparatus is configured to perform an automated full recruitment manoeuvre, FRM, comprising a recruitment phase and a PEEP titration phase, wherein the PEEP titration phase is a phase of stepwise decrease in PEEP from a maximum PEEP level to a minimum PEEP level, via one or more intermediate PEEP levels. The breathing apparatus is configured to deliver a number of breaths at each PEEP level, and to monitor a parameter indicative of a potentially harmful level of ventilation during the PEEP titration. The breathing apparatus is further configured to automatically decrease PEEP to a lower PEEP level when the monitored parameter reaches a first threshold value.

  • Patent number: 8646448
    Abstract: A ventilator provides breathing support to a patient in an EMG controlled mode, and has an input that receives an EMG signal representative of breathing activity from the patient and a control unit for controlling the ventilation in dependence of said EMG signal. The ventilator has a registration unit that registers the actual breathing support provided from the ventilator to the patient, and the control unit determines if there is asynchrony between the EMG signal and the breathing activity and, in case of asynchrony, causes a switch from EMG controlled ventilation to a second ventilation mode not dependent on the EMG signal. If synchrony is detected the ventilator can return to EMG controlled ventilation.

  • Publication number: 20110000489
    Abstract: To set trigger conditions correctly in pneumatic mode, a ventilator is controlled to obtain a measurement value of a bioelectric signal representative of the patient's breathing function, determine, based on the bioelectric signal, at least one point in time at which the patient starts inhalation, obtain a measurement value to be used for triggering an inspiration phase in the ventilator during the at least one point in time, determine a trigger condition for the inspiration phase on the basis of the measurement value, and use the trigger condition for initiating inspiration when ventilating the patient in support mode.
