Abstract
A ventilation system provides patient-triggered support ventilation to a spontaneously breathing patient during ongoing high frequency ventilation (HFV), and has a pneumatic unit operated by a control computer for delivery of breathing gas in response to an effort to breathe by the patient, and an oscillator for superimposing high frequency oscillation onto the breathing gas. The system further includes a bioelectric sensor that measures a bioelectric signal indicative of the patient's efforts to breathe, and the control computer controls the delivery of breathing gas in response to the patient's effort to breathe, based on this bioelectric signal. The ventilation system is hence designed for neurally triggered support ventilation during ongoing HFV, which makes the trigger mechanism of the ventilation system more precise and robust compared to known trigger mechanisms of HFV ventilation systems.
