AN EMG CONTROLLED VENTILATOR AND A METHOD FOR AN EMG CONTROLLED VENTILATOR

摘要

A ventilator (3) arranged to provide breathing support to a patient (1) in EMG controlled mode, comprises input means (7) for receiving an EMG signal representative of breathing activity from the patient and a control unit (9) for controlling the ventilation in dependence of said EMG signal. The ventilator is characterized in that it comprises registration means (11) for registering the actual breathing support provided from the ventilator to the patient and a control unit (7) arranged to determine if there is asynchrony between the EMG signal and the breathing activity and, in case of asynchrony, 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.
