Abstract
The present invention provides a high-frequency oscillation (HFO) artificial respiration apparatus comprising an inhale gas introduction block for supplying an inhale gas to a patient X, a patient-side path for guiding the inhale gas to the patient X, an oscillating air pressure urging block for applying an oscillating air pressure to the inhale gas, an exhaust path for exhausting an exhale gas exhaled from the patient X, and a controller for controlling operation of the oscillating air pressure urging block . The oscillating air pressure urging block includes a blower and a rotary valve . The controller includes an input block for accepting a ventilation frequency and a ventilation amount at a time for the patient and an operation control block for controlling the rotary valve and the blower according to values entered. The operation control block has a ventilation amount maintaining function for controlling an amplitude defined by the blower so that the ventilation amount at a time for the patient is maintained at a constant value when the oscillation frequency is modified.
