摘要：
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.
