摘要：
This invention concerns a breathing assistance apparatus capable of operatingin alternating inhalation and expiratory phases wherein a) the control meansof the apparatus comprise selection means (152) capable of selecting apressure parameter or a flow rate parameter to define b) the said referencevalue for the gas source, the said selection means are controlled by anautomatic control unit (51), the said control unit being: I) connected topressure and flow rate sensors situated on the inhalation duct to form adirect closed regulation loop for selecting a reference value parameter, II)associated to a programme allowing the selection to be made in real time froma pressure or flow rate signal, so that the association of a direct closedregulation circuit for the selection of a reference value parameter with avalve permitting proportional operation, allows real time control ofbarometric and volumetric operating modes of the apparatus, between theinhalation and expiratory phases and during these phases. The invention alsoconcerns associated operating processes.
