Abstract
A ventilator intended to be connected to a patient for breathing therapy has a control unit having an input for receiving EMG signals from an EMG detector and an output for an EMG based control signal and a pneumatic unit for generating breathing gas flows dependent on the EMG based control signal is described. The ventilator has a detector for determining a parameter related to breathing dynamics for the patient, this detector being connected to the control unit and control unit controlling the pneumatic unit dependent on the parameter related to breathing dynamics in the case of loss of EMG signals at the input.

21. A control unit for a ventilator configured for connection to a patient for breathing therapy, said control unit comprising:
-
a first control input that receives at least bioelectrical signal related to breathing by the patient; control circuitry that generates a control signal dependent on said at least one bioelectrical signal for controlling a pneumatic unit of the ventilator; a control output configured to output the control unit to the pneumatic unit; a second control input that receives, from a detector, a breathing parameter related to breathing dynamics of the patient; and said control circuitry determining whether said at least one bioelectrical signals is present at said first control input and generating said control signal to control said pneumatic unit dependent on said breathing parameter if no bioelectric signal is present at said first control input. - View Dependent Claims (22, 23, 24, 25, 26, 27)

32. A method for controlling a ventilator for providing breathing therapy to a patient, said ventilator comprising a pneumatic unit that generates breathing gas flows, comprising the steps of:
-
determining a presence of a bioelectrical signal related to breathing from the patient in a control unit; if said bioelectrical signal is present, generating a control signal that controls the pneumatic unit dependent on the bioelectrical signal; and if the bioelectrical signal is not present, generating a control signal that controls the pneumatic unit dependent on a breathing parameter obtained from at least one detector related to breathing dynamics of the patient. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39)

40. A computer readable medium encoded with programming instructions to control a pneumatic unit in a ventilator to provide breathing therapy to a patient, said programming instructions causing a control unit, that operates said pneumatic unit to:
-
determine a presence of a bioelectrical signal related to breathing from the patient in a control unit; if said bioelectrical signal is present, generate a control signal that controls the pneumatic unit dependent on the bioelectrical signal; and if the bioelectrical signal is not present, generate a control signal that controls the pneumatic unit dependent on a breathing parameter obtained from at least one detector related to breathing dynamics of the patient.
