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.

17. A computer-readable medium encoded with programming instructions, said medium being loaded into a computerized control unit of a ventilator that provides breathing support in a support mode to a patient, said programming instructions causing said computerized control unit to:
-
obtain a measurement value of a bioelectric signal representative of the breathing function of the patient; 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 said at least one point in time; determine a trigger condition for the inspiration phase based on said measurement value; and use said trigger condition to initiate inspiration when ventilating the patient in said support mode. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A control unit for a ventilator operated by a computer-readable medium comprising programming instructions, said programming instructions configuring said control unit to:
-
obtain a measurement value of a bioelectric signal representative of the breathing function of the patient; 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 said at least one point in time; determine a trigger condition for the inspiration phase based on said measurement value; and use said trigger condition to initiate inspiration when ventilating the patient in said support mode.

25. A ventilator comprising:
-
a breathing circuit adapted for connection to a patient, said breathing circuit being operable in a support mode to assist breathing by the patient; a control unit that operates said breathing circuit, said control unit being configured to obtain a measurement value of a bioelectric signal representative of the breathing function of the patient, 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 said at least one point in time, determine a trigger condition for the inspiration phase based on said measurement value, and use said trigger condition to initiate inspiration when ventilating the patient in said support mode.

26. A method for operating a computerized control unit of a ventilator that provides breathing support in a support mode to a patient, said method comprising the steps of:
-
obtaining a measurement value of a bioelectric signal representative of the breathing function of the patient; in a processor, determining, based on the bioelectric signal, at least one point in time at which the patient starts inhalation; obtaining a measurement value to be used for triggering an inspiration phase in the ventilator during said at least one point in time; in said processor, determining a trigger condition for the inspiration phase based on said measurement value; and from said processor, using said trigger condition to initiate inspiration when ventilating the patient in said support mode. - View Dependent Claims (27, 28, 29, 30, 31, 32)
