  • Patent number: 9238114
    Abstract: A process for automatic control of a respirator changes between two phases of respiration by checking a detected respiratory breathing activity signal for a threshold criterion. If the threshold criterion is met, a changeover is made.

  • Patent number: 9211384
    Abstract: A respirator or anesthesia system for respirating a patient (20) includes a gas delivery device (3); at least one gas line (4) for forming a breathing air line system, especially a breathing air circulation system; at least one EMG sensor for detecting the electromyographic muscle activity of the respiratory muscles of a patient (20) being respirated; and a control (9) for controlling and/or regulating the output of the gas delivery device (3) as a function of the detected muscle activity of the respiratory muscles. An adaptation of the part of respiration to the performance capacity of the respiratory muscles of the patient (20) being respirated is made possible without invasive measurement of the electromyographic activity of the respiratory muscles by the at least one EMG sensor being an sEMG sensor (6).

  • Patent number: 8939148
    Abstract: A process is provided for the automatic control of a respirator for changing over (triggering) between consecutive phases of respiration (inspiration and expiration phases), wherein a pneumatic breathing activity signal upneu(t) and a non-pneumatic breathing activity signal unon-pneu(t) of a patient are picked up. The intervals ?pneu(t) and ?non-pneu(t) to the associated threshold variables are respectively determined starting from a preset reference point in time since the beginning of the present phase of respiration. The intervals are standardized to one another at ?pneu(t) and ?non-pneu(t), such that the intervals have equal interval values at a preset reference point in time. The standardized intervals ?pneu(t) and ?non-pneu(t) are averaged to a mean interval indicator and a changeover is made into the next phase of respiration when the combined interval indicator is 0.

  • Patent number: 8707951
    Abstract: A process for controlling a respirator with reduced gas excess, wherein a load situation (37) of an expiration valve is polled in a continuous sequence and a flow value (36) is reduced step by step from a preset starting flow value (41) and wherein the flow value (36) is again increased when a predetermined value (44) is exceeded.

  • Patent number: 8695597
    Abstract: A process for operating a respirator and/or anesthesia device in the APRV mode with the % PEF criterion which includes a detection of a spontaneous expiratory effort by the patient and initiation of a pressure release phase when the detected spontaneous expiratory effort by the patient falls within a predetermined trigger window (Tfreg). A device is provided that is operated correspondingly.

  • Publication number: 20120152251
    Abstract: A process for automatic control of a respirator changes between two phases of respiration by checking a detected respiratory breathing activity signal for a threshold criterion. If the threshold criterion is met, a changeover is made. A dynamic threshold curve, used for changing over into an inspiration phase, is held, after the beginning of the present expiration phase, at high values until the end of a selected inspiratory refractory period, and is then lowered monotonically, dropping to an inspiratory threshold target value at the expected point in time of the phase duration maximum of the present expiration phase.

  • Publication number: 20120152249
    Abstract: A process for the automatic control of a respirator with a changeover between phases of respiration (inspiration and expiration), by a control unit checking a breathing activity signal for a threshold criterion. If the threshold criterion is met, a changeover is made and the control unit controls the fan of the respirator such that a pneumatic respiration variable (airway pressure, flow) is brought from an actual value to a preset target value for the new phase of respiration. The control unit further divides the change in the respiration variable, from the actual value to the target value, into a plurality of partial steps and checks the current breathing activity signal for the threshold criterion after each partial step. If this threshold criterion is no longer met, the state of operation of the respirator returns to the state before the last changeover, and otherwise, continues with the next partial step.
