摘要：The invention concerns a process for regulating a respiratory apparatus and therespiratory apparatus itself. The apparatus permits a succession of respiratory cyclesdepending on patient requirements, such as frequency FR (or respiratory rate RR). Thesuccession of respiratory cycles consists of an inspiration phase, during which the patientis supplied with a current tidal volume (VT) of respirable gaseous fluid, and an expirationphase. The patient has his/her own natural spontaneous respiration, and the pressure inthe patient's respiratory passages is defined as Paw. According to the the process, atheoretical respiration volume per minute value, called Vmn optical, is established as afunction of the patient's condition and natural spontaneous respiration. Other values arealso set or calculated. A minimum current tidal volume (VTmin) and a maximum allowableairway passage pressure, Paw max, are established. The total current tidal volume VTsupplied to the patient during each respiratory cycle is monitored, and the artificialrespiration is controlled to be within the set values VTmin and Paw max, and to satisfy therelation Vmn optimal=FR×VT in order to vary automatically the artificial respiration fromspontaneous breathing to controlled breathing, or vice versa, as a function of the
patient's natural spontaneous respiration.
