In the case of the inhalation device described in this publication, an insufflation catheter inserted into the trachea is insufflated using breathing gas pulses from a propellant breathing gas source. In this case, the pulse repetition rate can be increased by 20/min to 200/min, depending on physiological measurements, inter alia cardiac transfusion efficiency and blood gas composition. In this case, the minute ventilation remains unchanged and the respiratory gas volume is reduced in direct proportion to the rate of increase in the pulse repetition rate.

させるのが不十分であると思料される。 Other tests have shown that controlling the pulse repetition rate in the breathing gas pulse is not in all cases the optimal control of the inhalation device. The successive pulse trains and the rate of variation of their pulse repetition rate also vary widely as the measurement results of the gas analysis fluctuate, counteracting the desired overall device stabilization and further reducing this inhalation task to physiological breathing. It is considered that the adaptation to the cycle is insufficient.

容易に制御されることができる。 The task is such that the control device 7 causes the breathing gas supply to occur in the form of breathing gas pulse trains I i of different times and configurations at least 600 pulses/min, with pauses Im between the pulse trains I i ; During this pause, the control variable of the control device 7 is achieved by taking off the gas sample via the measuring line 4 which opens in the vicinity of the nozzle 3. Therefore, during one breathing stroke, one pulse packet containing one corresponding breathing pulse train is delivered, and the breathing pulse train and the pauses are determined by the optimal inhalation pattern that exists depending on the physiological or pathological lung condition at the breathing gas source. can be easily controlled to obtain

However, they also have different structures within one respiratory pulse train. In this case, the different structural concepts relate both to the quantities of the respective components, for example the oxygen concentration, and also to the amount of new components introduced, such as carbon dioxide or helium, for example.

する。 In order to clarify these relationships, it should be noted that "respiratory gas pulses" in this specification
The concept of atemgasimpuls relates to the minimum amount of gas that must be supplied by a breathing gas source.
A predetermined number of breathing gas pulses is a “breathing pulse train”
(Atemipulsreihe), i.e. pulse packets are formed, which are delivered throughout the inhalation cycle. In each pulse packet, the respiratory gas pulses specify the "microscopic" phenomena of the respiratory cycle by their amount and composition and their pulse repetition rate, while the respiratory pulse train (pulse packet) specifies the "macroscopic" phenomena of the inhalation with the pauses. and limit the “breath repetition rate” (Atemfrequenz).
