  • This flow generator is associated a controlled expiration device, without a member for regulation of the supplemental principal flow.
  • the detection of an increasing slope of pressure can be translated by a level of acceleration of the turbine 2 a and the detection of the transition between the inspiration phase and the expiration phase can be translated by a deceleration of the turbine 2 a.

  • a limiting parameter for the time of insufflation is the minimum threshold corresponding to the slope of pressure measured; another parameter is a maximum threshold of safety for the insufflation time which corresponds to the last inspiration time carried out or at most to three seconds.
  • Other safety parameters can be taken into account such as a safety frequency.
  • the objective of the insufflation phase is the establishment of a pressure level Pi with a variable time of increase and a holding time depending on the behavior of the associated flow rate.
  • the objective of the expiration phase is to maintain a pressure level Pe up to the beginning of the following inspiration phase, but also sufficiently to rinse the circuit so as to evacuate the residual expired gases.
  • the phases of pressure increase with increased slopes of pressure are carried out by an acceleration of the turbine 2 a.
  • the pressure is controlled in the inspiration pressure sensor 6 .
  • the computation means control the expiration valve 14 , which is part of the third circuit 11 connected to the mask 4 or to the intubation device, via the proportional electro-valve 15 and the second circuit 16 , according to pressure.

  • the non-return clapet system 12 and the spontaneous respiration clapet 13 permit balancing the rinsing pressure which is maintained sufficiently low to limit the phenomenon of expiration braking without being canceled to avoid all heating of the turbine 2 a.
  • the objective of the insufflation phase is the distribution of a current volume Vt with a suitable flow rate shape and during a time fixed by the frequency levels and the ratio of cycling regulated by the interface 25 .
  • the operator enters by the interface means a target volume standard into the computation means 9 which, as a function of this parameter and other parameters entered by the interface such as the frequency of minimum cycle and/or safety, cycling ratio, high pressure threshold, will permanently adjust the insufflation pressure between a low pressure threshold and a maximum pressure threshold so as to maintain the current volume inhaled by the patient as nearly as possible to a predefined target volume, namely for example between target volume Vt and target volume Vt+20%.
  • the target volume mode it is particularly necessary to be able at the same time to adjust precisely the pressure by pressure steps between the cycles.
  • the steps between cycles are defined between 0.5 millibar and 2 millibars so as to react immediately to the detection of an unbalance without having a strong reaction that would be uncomfortable to the patient.
  • This pressure adjustment is made according to the invention without a regulator device such as the generator but by controlling the speed of the turbine 2 a of the generator 2 as a function of the pressure measurements of the sensor 6 of the pressure of the patient and by causing to operate the expiration circuit comprising the expiration valve 14 following through the proportional electro-valve 15 in which, in this configuration, the flow generator is connected to the second circuit, the non-return flap 12 of the first circuit 3 permitting preserving a pressure slightly greater in the second circuit relative to the first circuit.
